+The Linux Kernel Driver Model is a unification of all the disparate driver
+models that were previously used in the kernel. It is intended to augment the
 bus-specific drivers for bridges and devices by consolidating a set of data
 and operations into globally accessible data structures.
 
-Current driver models implement some sort of tree-like structure (sometimes
-just a list) for the devices they control. But, there is no linkage between
-the different bus types.
+Traditional driver models implemented some sort of tree-like structure
+(sometimes just a list) for the devices they control. There wasn't any
+uniformity across the different bus types.
 
-A common data structure can provide this linkage with little overhead: when a
-bus driver discovers a particular device, it can insert it into the global
-tree as well as its local tree. In fact, the local tree becomes just a subset
-of the global tree.
-
-Common data fields can also be moved out of the local bus models into the
-global model. Some of the manipulations of these fields can also be
-consolidated. Most likely, manipulation functions will become a set
-of helper functions, which the bus drivers wrap around to include any
-bus-specific items.
-
-The common device and bridge interface currently reflects the goals of the
-modern PC: namely the ability to do seamless Plug and Play, power management,
-and hot plug. (The model dictated by Intel and Microsoft (read: ACPI) ensures
-us that any device in the system may fit any of these criteria.)
-
-In reality, not every bus will be able to support such operations. But, most
-buses will support a majority of those operations, and all future buses will.
-In other words, a bus that doesn't support an operation is the exception,
-instead of the other way around.
+The current driver model provides a comon, uniform data model for describing
+a bus and the devices that can appear under the bus. The unified bus
+model includes a set of common attributes which all busses carry, and a set
+of common callbacks, such as device discovery during bus probing, bus
+shutdown, bus power management, etc.
 
+The common device and bridge interface reflects the goals of the modern
+computer: namely the ability to do seamless device "plug and play", power
+management, and hot plug. In particular, the model dictated by Intel and
+Microsoft (namely ACPI) ensures that almost every device on almost any bus
+on an x86-compatible system can work within this paradigm.  Of course,
+not every bus is able to support all such operations, although most
+buses support a most of those operations.

+				 =================================
+				 INTERNAL KERNEL ABI FOR FR-V ARCH
+				 =================================
+
+The internal FRV kernel ABI is not quite the same as the userspace ABI. A number of the registers
+are used for special purposed, and the ABI is not consistent between modules vs core, and MMU vs
+no-MMU.
+
+This partly stems from the fact that FRV CPUs do not have a separate supervisor stack pointer, and
+most of them do not have any scratch registers, thus requiring at least one general purpose
+register to be clobbered in such an event. Also, within the kernel core, it is possible to simply
+jump or call directly between functions using a relative offset. This cannot be extended to modules
+for the displacement is likely to be too far. Thus in modules the address of a function to call
+must be calculated in a register and then used, requiring two extra instructions.
+
+This document has the following sections:
+
+ (*) System call register ABI
+ (*) CPU operating modes
+ (*) Internal kernel-mode register ABI
+ (*) Internal debug-mode register ABI
+ (*) Virtual interrupt handling
+
+
+========================
+SYSTEM CALL REGISTER ABI
+========================
+
+When a system call is made, the following registers are effective:
+
+	REGISTERS	CALL			RETURN
+	===============	=======================	=======================
+	GR7		System call number	Preserved
+	GR8		Syscall arg #1		Return value
+	GR9-GR13	Syscall arg #2-6	Preserved
+
+
+===================
+CPU OPERATING MODES
+===================
+
+The FR-V CPU has three basic operating modes. In order of increasing capability:
+
+  (1) User mode.
+
+      Basic userspace running mode.
+
+  (2) Kernel mode.
+
+      Normal kernel mode. There are many additional control registers available that may be
+      accessed in this mode, in addition to all the stuff available to user mode. This has two
+      submodes:
+
+      (a) Exceptions enabled (PSR.T == 1).
+
+      	  Exceptions will invoke the appropriate normal kernel mode handler. On entry to the
+      	  handler, the PSR.T bit will be cleared.
+
+      (b) Exceptions disabled (PSR.T == 0).
+
+      	  No exceptions or interrupts may happen. Any mandatory exceptions will cause the CPU to
+      	  halt unless the CPU is told to jump into debug mode instead.
+
+  (3) Debug mode.
+
+      No exceptions may happen in this mode. Memory protection and management exceptions will be
+      flagged for later consideration, but the exception handler won't be invoked. Debugging traps
+      such as hardware breakpoints and watchpoints will be ignored. This mode is entered only by
+      debugging events obtained from the other two modes.
+
+      All kernel mode registers may be accessed, plus a few extra debugging specific registers.
+
+
+=================================
+INTERNAL KERNEL-MODE REGISTER ABI
+=================================
+
+There are a number of permanent register assignments that are set up by entry.S in the exception
+prologue. Note that there is a complete set of exception prologues for each of user->kernel
+transition and kernel->kernel transition. There are also user->debug and kernel->debug mode
+transition prologues.
+
+
+	REGISTER	FLAVOUR	USE
+	===============	=======	====================================================
+	GR1			Supervisor stack pointer
+	GR15			Current thread info pointer
+	GR16			GP-Rel base register for small data
+	GR28			Current exception frame pointer (__frame)
+	GR29			Current task pointer (current)
+	GR30			Destroyed by kernel mode entry
+	GR31		NOMMU	Destroyed by debug mode entry
+	GR31		MMU	Destroyed by TLB miss kernel mode entry
+	CCR.ICC2		Virtual interrupt disablement tracking
+	CCCR.CC3		Cleared by exception prologue (atomic op emulation)
+	SCR0		MMU	See mmu-layout.txt.
+	SCR1		MMU	See mmu-layout.txt.
+	SCR2		MMU	Save for EAR0 (destroyed by icache insns in debug mode)
+	SCR3		MMU	Save for GR31 during debug exceptions
+	DAMR/IAMR	NOMMU	Fixed memory protection layout.
+	DAMR/IAMR	MMU	See mmu-layout.txt.
+
+
+Certain registers are also used or modified across function calls:
+
+	REGISTER	CALL				RETURN
+	===============	===============================	===============================
+	GR0		Fixed Zero			-
+	GR2		Function call frame pointer
+	GR3		Special				Preserved
+	GR3-GR7		-				Clobbered
+	GR8		Function call arg #1		Return value (or clobbered)
+	GR9		Function call arg #2		Return value MSW (or clobbered)
+	GR10-GR13	Function call arg #3-#6		Clobbered
+	GR14		-				Clobbered
+	GR15-GR16	Special				Preserved
+	GR17-GR27	-				Preserved
+	GR28-GR31	Special				Only accessed explicitly
+	LR		Return address after CALL	Clobbered
+	CCR/CCCR	-				Mostly Clobbered
+
+
+================================
+INTERNAL DEBUG-MODE REGISTER ABI
+================================
+
+This is the same as the kernel-mode register ABI for functions calls. The difference is that in
+debug-mode there's a different stack and a different exception frame. Almost all the global
+registers from kernel-mode (including the stack pointer) may be changed.
+
+	REGISTER	FLAVOUR	USE
+	===============	=======	====================================================
+	GR1			Debug stack pointer
+	GR16			GP-Rel base register for small data
+	GR31			Current debug exception frame pointer (__debug_frame)
+	SCR3		MMU	Saved value of GR31
+
+
+Note that debug mode is able to interfere with the kernel's emulated atomic ops, so it must be
+exceedingly careful not to do any that would interact with the main kernel in this regard. Hence
+the debug mode code (gdbstub) is almost completely self-contained. The only external code used is
+the sprintf family of functions.
+
+Futhermore, break.S is so complicated because single-step mode does not switch off on entry to an
+exception. That means unless manually disabled, single-stepping will blithely go on stepping into
+things like interrupts. See gdbstub.txt for more information.
+
+
+==========================
+VIRTUAL INTERRUPT HANDLING
+==========================
+
+Because accesses to the PSR is so slow, and to disable interrupts we have to access it twice (once
+to read and once to write), we don't actually disable interrupts at all if we don't have to. What
+we do instead is use the ICC2 condition code flags to note virtual disablement, such that if we
+then do take an interrupt, we note the flag, really disable interrupts, set another flag and resume
+execution at the point the interrupt happened. Setting condition flags as a side effect of an
+arithmetic or logical instruction is really fast. This use of the ICC2 only occurs within the
+kernel - it does not affect userspace.
+
+The flags we use are:
+
+ (*) CCR.ICC2.Z [Zero flag]
+
+     Set to virtually disable interrupts, clear when interrupts are virtually enabled. Can be
+     modified by logical instructions without affecting the Carry flag.
+
+ (*) CCR.ICC2.C [Carry flag]
+
+     Clear to indicate hardware interrupts are really disabled, set otherwise.
+
+
+What happens is this:
+
+ (1) Normal kernel-mode operation.
+
+	ICC2.Z is 0, ICC2.C is 1.
+
+ (2) An interrupt occurs. The exception prologue examines ICC2.Z and determines that nothing needs
+     doing. This is done simply with an unlikely BEQ instruction.
+
+ (3) The interrupts are disabled (local_irq_disable)
+
+	ICC2.Z is set to 1.
+
+ (4) If interrupts were then re-enabled (local_irq_enable):
+
+	ICC2.Z would be set to 0.
+
+     A TIHI #2 instruction (trap #2 if condition HI - Z==0 && C==0) would be used to trap if
+     interrupts were now virtually enabled, but physically disabled - which they're not, so the
+     trap isn't taken. The kernel would then be back to state (1).
+
+ (5) An interrupt occurs. The exception prologue examines ICC2.Z and determines that the interrupt
+     shouldn't actually have happened. It jumps aside, and there disabled interrupts by setting
+     PSR.PIL to 14 and then it clears ICC2.C.
+
+ (6) If interrupts were then saved and disabled again (local_irq_save):
+
+	ICC2.Z would be shifted into the save variable and masked off (giving a 1).
+
+	ICC2.Z would then be set to 1 (thus unchanged), and ICC2.C would be unaffected (ie: 0).
+
+ (7) If interrupts were then restored from state (6) (local_irq_restore):
+
+	ICC2.Z would be set to indicate the result of XOR'ing the saved value (ie: 1) with 1, which
+	gives a result of 0 - thus leaving ICC2.Z set.
+
+	ICC2.C would remain unaffected (ie: 0).
+
+     A TIHI #2 instruction would be used to again assay the current state, but this would do
+     nothing as Z==1.
+
+ (8) If interrupts were then enabled (local_irq_enable):
+
+	ICC2.Z would be cleared. ICC2.C would be left unaffected. Both flags would now be 0.
+
+     A TIHI #2 instruction again issued to assay the current state would then trap as both Z==0
+     [interrupts virtually enabled] and C==0 [interrupts really disabled] would then be true.
+
+ (9) The trap #2 handler would simply enable hardware interrupts (set PSR.PIL to 0), set ICC2.C to
+     1 and return.
+
+(10) Immediately upon returning, the pending interrupt would be taken.
+
+(11) The interrupt handler would take the path of actually processing the interrupt (ICC2.Z is
+     clear, BEQ fails as per step (2)).
+
+(12) The interrupt handler would then set ICC2.C to 1 since hardware interrupts are definitely
+     enabled - or else the kernel wouldn't be here.
+
+(13) On return from the interrupt handler, things would be back to state (1).
+
+This trap (#2) is only available in kernel mode. In user mode it will result in SIGILL.

+
+Thanks to Chris Lin from Jetway for providing wiring schematics and

+
+
+Description
+-----------
+
+The Fintek F71805F/FG Super I/O chip includes complete hardware monitoring
+capabilities. It can monitor up to 9 voltages (counting its own power
+source), 3 fans and 3 temperature sensors.
+
+This chip also has fan controlling features, using either DC or PWM, in
+three different modes (one manual, two automatic). The driver doesn't
+support these features yet.
+
+The driver assumes that no more than one chip is present, which seems
+reasonable.
+
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled by an 8-bit ADC with a LSB of 8 mV. The supported
+range is thus from 0 to 2.040 V. Voltage values outside of this range
+need external resistors. An exception is in0, which is used to monitor
+the chip's own power source (+3.3V), and is divided internally by a
+factor 2.
+
+The two LSB of the voltage limit registers are not used (always 0), so
+you can only set the limits in steps of 32 mV (before scaling).
+
+The wirings and resistor values suggested by Fintek are as follow:
+
+        pin                                           expected
+        name    use           R1      R2     divider  raw val.

+in4     VIN4    VCC5V       200K     47K        5.25    0.95 V
+in5     VIN5    +12V        200K     20K       11.00    1.05 V
+in6     VIN6    VCC1.5V      10K       -        1.00    1.50 V
+in7     VIN7    VCORE        10K       -        1.00   ~1.40 V (1)
+in8     VIN8    VSB5V       200K     47K        1.00    0.95 V
+
+(1) Depends on your hardware setup.
+(2) Obviously not correct, swapping R1 and R2 would make more sense.
+
+These values can be used as hints at best, as motherboard manufacturers
+are free to use a completely different setup. As a matter of fact, the
+Jetway K8M8MS uses a significantly different setup. You will have to
+find out documentation about your own motherboard, and edit sensors.conf
+accordingly.
+
+Each voltage measured has associated low and high limits, each of which
+triggers an alarm when crossed.
+
+
+Fan Monitoring
+--------------
+
+Fan rotation speeds are reported as 12-bit values from a gated clock
+signal. Speeds down to 366 RPM can be measured. There is no theoretical
+high limit, but values over 6000 RPM seem to cause problem. The effective
+resolution is much lower than you would expect, the step between different
+register values being 10 rather than 1.
+
+The chip assumes 2 pulse-per-revolution fans.
+
+An alarm is triggered if the rotation speed drops below a programmable
+limit or is too low to be measured.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in degrees Celsius. Each temperature measured
+has a high limit, those crossing triggers an alarm. There is an associated
+hysteresis value, below which the temperature has to drop before the
+alarm is cleared.
+
+All temperature channels are external, there is no embedded temperature
+sensor. Each channel can be used for connecting either a thermal diode
+or a thermistor. The driver reports the currently selected mode, but
+doesn't allow changing it. In theory, the BIOS should have configured
+everything properly.

+Many PCI bus controllers are able to detect a variety of hardware
+PCI errors on the bus, such as parity errors on the data and address
+busses, as well as SERR and PERR errors.  Some of the more advanced
+chipsets are able to deal with these errors; these include PCI-E chipsets,
+and the PCI-host bridges found on IBM Power4 and Power5-based pSeries
+boxes. A typical action taken is to disconnect the affected device,
+halting all I/O to it.  The goal of a disconnection is to avoid system
+corruption; for example, to halt system memory corruption due to DMA's
+to "wild" addresses. Typically, a reconnection mechanism is also
+offered, so that the affected PCI device(s) are reset and put back
+into working condition. The reset phase requires coordination
+between the affected device drivers and the PCI controller chip.
+This document describes a generic API for notifying device drivers
+of a bus disconnection, and then performing error recovery.
+This API is currently implemented in the 2.6.16 and later kernels.
+
+Reporting and recovery is performed in several steps. First, when
+a PCI hardware error has resulted in a bus disconnect, that event
+is reported as soon as possible to all affected device drivers,
+including multiple instances of a device driver on multi-function
+cards. This allows device drivers to avoid deadlocking in spinloops,
+waiting for some i/o-space register to change, when it never will.
+It also gives the drivers a chance to defer incoming I/O as
+needed.
+
+Next, recovery is performed in several stages. Most of the complexity
+is forced by the need to handle multi-function devices, that is,
+devices that have multiple device drivers associated with them.
+In the first stage, each driver is allowed to indicate what type
+of reset it desires, the choices being a simple re-enabling of I/O
+or requesting a hard reset (a full electrical #RST of the PCI card).
+If any driver requests a full reset, that is what will be done.
+
+After a full reset and/or a re-enabling of I/O, all drivers are
+again notified, so that they may then perform any device setup/config
+that may be required.  After these have all completed, a final
+"resume normal operations" event is sent out.
+
+The biggest reason for choosing a kernel-based implementation rather
+than a user-space implementation was the need to deal with bus
+disconnects of PCI devices attached to storage media, and, in particular,
+disconnects from devices holding the root file system.  If the root
+file system is disconnected, a user-space mechanism would have to go
+through a large number of contortions to complete recovery. Almost all
+of the current Linux file systems are not tolerant of disconnection
+from/reconnection to their underlying block device. By contrast,
+bus errors are easy to manage in the device driver. Indeed, most
+device drivers already handle very similar recovery procedures;
+for example, the SCSI-generic layer already provides significant
+mechanisms for dealing with SCSI bus errors and SCSI bus resets.
+
+
+Detailed Design
+---------------
+Design and implementation details below, based on a chain of
+public email discussions with Ben Herrenschmidt, circa 5 April 2005.
 
 The error recovery API support is exposed to the driver in the form of
 a structure of function pointers pointed to by a new field in struct
-pci_driver. The absence of this pointer in pci_driver denotes an
-"non-aware" driver, behaviour on these is platform dependant.
-Platforms like ppc64 can try to simulate pci hotplug remove/add.
-
-The definition of "pci_error_token" is not covered here. It is based on
-Seto's work on the synchronous error detection. We still need to define
-functions for extracting infos out of an opaque error token. This is
-separate from this API.
+pci_driver. A driver that fails to provide the structure is "non-aware",
+and the actual recovery steps taken are platform dependent.  The
+arch/powerpc implementation will simulate a PCI hotplug remove/add.
 
 This structure has the form:
-
 struct pci_error_handlers
 {
-	int (*error_detected)(struct pci_dev *dev, pci_error_token error);
+	int (*error_detected)(struct pci_dev *dev, enum pci_channel_state);
 	int (*mmio_enabled)(struct pci_dev *dev);
-	int (*resume)(struct pci_dev *dev);
 	int (*link_reset)(struct pci_dev *dev);
 	int (*slot_reset)(struct pci_dev *dev);
+	void (*resume)(struct pci_dev *dev);
 };
 
-A driver doesn't have to implement all of these callbacks. The
-only mandatory one is error_detected(). If a callback is not
-implemented, the corresponding feature is considered unsupported.
-For example, if mmio_enabled() and resume() aren't there, then the
-driver is assumed as not doing any direct recovery and requires
+The possible channel states are:
+enum pci_channel_state {
+	pci_channel_io_normal,  /* I/O channel is in normal state */
+	pci_channel_io_frozen,  /* I/O to channel is blocked */
+	pci_channel_io_perm_failure, /* PCI card is dead */
+};
+
+Possible return values are:
+enum pci_ers_result {
+	PCI_ERS_RESULT_NONE,        /* no result/none/not supported in device driver */
+	PCI_ERS_RESULT_CAN_RECOVER, /* Device driver can recover without slot reset */
+	PCI_ERS_RESULT_NEED_RESET,  /* Device driver wants slot to be reset. */
+	PCI_ERS_RESULT_DISCONNECT,  /* Device has completely failed, is unrecoverable */
+	PCI_ERS_RESULT_RECOVERED,   /* Device driver is fully recovered and operational */
+};
+
+A driver does not have to implement all of these callbacks; however,
+if it implements any, it must implement error_detected(). If a callback
+is not implemented, the corresponding feature is considered unsupported.
+For example, if mmio_enabled() and resume() aren't there, then it
+is assumed that the driver is not doing any direct recovery and requires
 a reset. If link_reset() is not implemented, the card is assumed as
-not caring about link resets, in which case, if recover is supported,
-the core can try recover (but not slot_reset() unless it really did
-reset the slot). If slot_reset() is not supported, link_reset() can
-be called instead on a slot reset.
-
-At first, the call will always be :
-
-	1) error_detected()
-
-	Error detected. This is sent once after an error has been detected. At
-this point, the device might not be accessible anymore depending on the
-platform (the slot will be isolated on ppc64). The driver may already
-have "noticed" the error because of a failing IO, but this is the proper
-"synchronisation point", that is, it gives a chance to the driver to
-cleanup, waiting for pending stuff (timers, whatever, etc...) to
-complete; it can take semaphores, schedule, etc... everything but touch
-the device. Within this function and after it returns, the driver
+not care about link resets. Typically a driver will want to know about
+a slot_reset().
+
+The actual steps taken by a platform to recover from a PCI error
+event will be platform-dependent, but will follow the general
+sequence described below.
+
+STEP 0: Error Event
+-------------------
+PCI bus error is detect by the PCI hardware.  On powerpc, the slot
+is isolated, in that all I/O is blocked: all reads return 0xffffffff,
+all writes are ignored.
+
+
+STEP 1: Notification
+--------------------
+Platform calls the error_detected() callback on every instance of
+every driver affected by the error.
+
+At this point, the device might not be accessible anymore, depending on
+the platform (the slot will be isolated on powerpc). The driver may
+already have "noticed" the error because of a failing I/O, but this
+is the proper "synchronization point", that is, it gives the driver
+a chance to cleanup, waiting for pending stuff (timers, whatever, etc...)
+to complete; it can take semaphores, schedule, etc... everything but
+touch the device. Within this function and after it returns, the driver
 shouldn't do any new IOs. Called in task context. This is sort of a
 "quiesce" point. See note about interrupts at the end of this doc.
 
-	Result codes:
-		- PCIERR_RESULT_CAN_RECOVER:

+All drivers participating in this system must implement this call.
+The driver must return one of the following result codes:
+		- PCI_ERS_RESULT_CAN_RECOVER:
+		  Driver returns this if it thinks it might be able to recover
 		  the HW by just banging IOs or if it wants to be given

-		- PCIERR_RESULT_DISCONNECT:
-		  Return this if driver thinks it won't recover at all,
-		  (this will detach the driver ? or just leave it
-		  dangling ? to be decided)
-
-So at this point, we have called error_detected() for all drivers
-on the segment that had the error. On ppc64, the slot is isolated. What
-happens now typically depends on the result from the drivers. If all
-drivers on the segment/slot return PCIERR_RESULT_CAN_RECOVER, we would
-re-enable IOs on the slot (or do nothing special if the platform doesn't
-isolate slots) and call 2). If not and we can reset slots, we go to 4),
-if neither, we have a dead slot. If it's an hotplug slot, we might
-"simulate" reset by triggering HW unplug/replug though.

+STEP 3: Link Reset
+------------------
+The platform resets the link, and then calls the link_reset() callback
+on all affected device drivers.  This is a PCI-Express specific state
+and is done whenever a non-fatal error has been detected that can be
+"solved" by resetting the link. This call informs the driver of the
+reset and the driver should check to see if the device appears to be
+in working condition.
+
+The driver is not supposed to restart normal driver I/O operations
+at this point.  It should limit itself to "probing" the device to

+will call resume() once all drivers have ack'd link_reset().
 
 	Result codes:

+		(identical to STEP 3 (MMIO Enabled)
+
+The platform then proceeds to either STEP 4 (Slot Reset) or STEP 5
+(Resume Operations).
+
+>>> The current powerpc implementation does not implement this callback.
+
+
+STEP 4: Slot Reset
+------------------
+The platform performs a soft or hard reset of the device, and then
+calls the slot_reset() callback.
+
+A soft reset consists of asserting the adapter #RST line and then
+restoring the PCI BAR's and PCI configuration header to a state
+that is equivalent to what it would be after a fresh system
+power-on followed by power-on BIOS/system firmware initialization.
+If the platform supports PCI hotplug, then the reset might be
+performed by toggling the slot electrical power off/on.
 
->>> The current ppc64 implementation does not implement this callback.
+It is important for the platform to restore the PCI config space
+to the "fresh poweron" state, rather than the "last state". After
+a slot reset, the device driver will almost always use its standard
+device initialization routines, and an unusual config space setup
+may result in hung devices, kernel panics, or silent data corruption.
 
-	4) slot_reset()
+This call gives drivers the chance to re-initialize the hardware
+(re-download firmware, etc.).  At this point, the driver may assume
+that he card is in a fresh state and is fully functional. In
+particular, interrupt generation should work normally.
 
-	This is called after the slot has been soft or hard reset by the
-platform.  A soft reset consists of asserting the adapter #RST line
-and then restoring the PCI BARs and PCI configuration header. If the
-platform supports PCI hotplug, then it might instead perform a hard
-reset by toggling power on the slot off/on. This call gives drivers
-the chance to re-initialize the hardware (re-download firmware, etc.),
-but drivers shouldn't restart normal I/O processing operations at
-this point.  (See note about interrupts; interrupts aren't guaranteed
-to be delivered until the resume() callback has been called). If all
-device drivers report success on this callback, the patform will call
-resume() to complete the error handling and let the driver restart
-normal I/O processing.
+Drivers should not yet restart normal I/O processing operations
+at this point.  If all device drivers report success on this
+callback, the platform will call resume() to complete the sequence,
+and let the driver restart normal I/O processing.
 
 A driver can still return a critical failure for this function if
 it can't get the device operational after reset.  If the platform
-previously tried a soft reset, it migh now try a hard reset (power
+previously tried a soft reset, it might now try a hard reset (power
 cycle) and then call slot_reset() again.  It the device still can't
 be recovered, there is nothing more that can be done;  the platform
 will typically report a "permanent failure" in such a case.  The
 device will be considered "dead" in this case.
 
-	Result codes:
-		- PCIERR_RESULT_DISCONNECT
-		Same as above.
+Drivers for multi-function cards will need to coordinate among
+themselves as to which driver instance will perform any "one-shot"
+or global device initialization. For example, the Symbios sym53cxx2
+driver performs device init only from PCI function 0:

->>> if the driver returned PCIERR_RESULT_DISCONNECT. However, it should.
++       if (PCI_FUNC(pdev->devfn) == 0)
++               sym_reset_scsi_bus(np, 0);
 
-	5) resume()
-
-	This is called if all drivers on the segment have returned
-PCIERR_RESULT_RECOVERED from one of the 3 prevous callbacks.

+Failure).
+
+>>> The current powerpc implementation does not currently try a
+>>> power-cycle reset if the driver returned PCI_ERS_RESULT_DISCONNECT.
+>>> However, it probably should.
+
+
+STEP 5: Resume Operations
+-------------------------
+The platform will call the resume() callback on all affected device
+drivers if all drivers on the segment have returned
+PCI_ERS_RESULT_RECOVERED from one of the 3 previous callbacks.
+The goal of this callback is to tell the driver to restart activity,
+that everything is back and running. This callback does not return
+a result code.
+
+At this point, if a new error happens, the platform will restart
+a new error recovery sequence.
+
+STEP 6: Permanent Failure
+-------------------------
+A "permanent failure" has occurred, and the platform cannot recover
+the device.  The platform will call error_detected() with a
+pci_channel_state value of pci_channel_io_perm_failure.
+
+The device driver should, at this point, assume the worst. It should
+cancel all pending I/O, refuse all new I/O, returning -EIO to
+higher layers. The device driver should then clean up all of its
+memory and remove itself from kernel operations, much as it would
+during system shutdown.
+
+The platform will typically notify the system operator of the
+permanent failure in some way.  If the device is hotplug-capable,
+the operator will probably want to remove and replace the device.
+Note, however, not all failures are truly "permanent". Some are
+caused by over-heating, some by a poorly seated card. Many
+PCI error events are caused by software bugs, e.g. DMA's to
+wild addresses or bogus split transactions due to programming
+errors. See the discussion in powerpc/eeh-pci-error-recovery.txt
+for additional detail on real-life experience of the causes of
+software errors.
+
+
+Conclusion; General Remarks
+---------------------------
+The way those callbacks are called is platform policy. A platform with
+no slot reset capability may want to just "ignore" drivers that can't
 recover (disconnect them) and try to let other cards on the same segment
 recover. Keep in mind that in most real life cases, though, there will
 be only one driver per segment.

+
+I - Introduction
+================
+
+During the recent development of the Linux/ppc64 kernel, and more
+specifically, the addition of new platform types outside of the old
+IBM pSeries/iSeries pair, it was decided to enforce some strict rules
+regarding the kernel entry and bootloader <-> kernel interfaces, in
+order to avoid the degeneration that had become the ppc32 kernel entry
+point and the way a new platform should be added to the kernel. The
+legacy iSeries platform breaks those rules as it predates this scheme,
+but no new board support will be accepted in the main tree that
+doesn't follows them properly.  In addition, since the advent of the
+arch/powerpc merged architecture for ppc32 and ppc64, new 32-bit
+platforms and 32-bit platforms which move into arch/powerpc will be
+required to use these rules as well.
+
+The main requirement that will be defined in more detail below is
+the presence of a device-tree whose format is defined after Open
+Firmware specification. However, in order to make life easier
+to embedded board vendors, the kernel doesn't require the device-tree
+to represent every device in the system and only requires some nodes
+and properties to be present. This will be described in detail in
+section III, but, for example, the kernel does not require you to
+create a node for every PCI device in the system. It is a requirement
+to have a node for PCI host bridges in order to provide interrupt
+routing informations and memory/IO ranges, among others. It is also
+recommended to define nodes for on chip devices and other busses that
+don't specifically fit in an existing OF specification. This creates a
+great flexibility in the way the kernel can then probe those and match
+drivers to device, without having to hard code all sorts of tables. It
+also makes it more flexible for board vendors to do minor hardware
+upgrades without significantly impacting the kernel code or cluttering
+it with special cases.
+
+
+1) Entry point for arch/powerpc
+-------------------------------
+
+   There is one and one single entry point to the kernel, at the start
+   of the kernel image. That entry point supports two calling
+   conventions:
+
+        a) Boot from Open Firmware. If your firmware is compatible
+        with Open Firmware (IEEE 1275) or provides an OF compatible
+        client interface API (support for "interpret" callback of
+        forth words isn't required), you can enter the kernel with:
+
+              r5 : OF callback pointer as defined by IEEE 1275
+              bindings to powerpc. Only the 32 bit client interface
+              is currently supported
+
+              r3, r4 : address & length of an initrd if any or 0
+
+              The MMU is either on or off; the kernel will run the
+              trampoline located in arch/powerpc/kernel/prom_init.c to
+              extract the device-tree and other information from open
+              firmware and build a flattened device-tree as described
+              in b). prom_init() will then re-enter the kernel using
+              the second method. This trampoline code runs in the
+              context of the firmware, which is supposed to handle all
+              exceptions during that time.
+
+        b) Direct entry with a flattened device-tree block. This entry
+        point is called by a) after the OF trampoline and can also be
+        called directly by a bootloader that does not support the Open
+        Firmware client interface. It is also used by "kexec" to
+        implement "hot" booting of a new kernel from a previous
+        running one. This method is what I will describe in more
+        details in this document, as method a) is simply standard Open
+        Firmware, and thus should be implemented according to the
+        various standard documents defining it and its binding to the
+        PowerPC platform. The entry point definition then becomes:
+
+                r3 : physical pointer to the device-tree block
+                (defined in chapter II) in RAM
+
+                r4 : physical pointer to the kernel itself. This is
+                used by the assembly code to properly disable the MMU
+                in case you are entering the kernel with MMU enabled
+                and a non-1:1 mapping.
+
+                r5 : NULL (as to differenciate with method a)
+
+        Note about SMP entry: Either your firmware puts your other
+        CPUs in some sleep loop or spin loop in ROM where you can get
+        them out via a soft reset or some other means, in which case
+        you don't need to care, or you'll have to enter the kernel
+        with all CPUs. The way to do that with method b) will be
+        described in a later revision of this document.
+
+
+2) Board support
+----------------
+
+64-bit kernels:
+
+   Board supports (platforms) are not exclusive config options. An
+   arbitrary set of board supports can be built in a single kernel
+   image. The kernel will "know" what set of functions to use for a
+   given platform based on the content of the device-tree. Thus, you
+   should:
+
+        a) add your platform support as a _boolean_ option in
+        arch/powerpc/Kconfig, following the example of PPC_PSERIES,
+        PPC_PMAC and PPC_MAPLE. The later is probably a good
+        example of a board support to start from.
+
+        b) create your main platform file as
+        "arch/powerpc/platforms/myplatform/myboard_setup.c" and add it
+        to the Makefile under the condition of your CONFIG_
+        option. This file will define a structure of type "ppc_md"
+        containing the various callbacks that the generic code will
+        use to get to your platform specific code
+
+        c) Add a reference to your "ppc_md" structure in the
+        "machines" table in arch/powerpc/kernel/setup_64.c if you are
+        a 64-bit platform.
+
+        d) request and get assigned a platform number (see PLATFORM_*
+        constants in include/asm-powerpc/processor.h
+
+32-bit embedded kernels:
+
+  Currently, board support is essentially an exclusive config option.
+  The kernel is configured for a single platform.  Part of the reason
+  for this is to keep kernels on embedded systems small and efficient;
+  part of this is due to the fact the code is already that way. In the
+  future, a kernel may support multiple platforms, but only if the
+  platforms feature the same core architectire.  A single kernel build
+  cannot support both configurations with Book E and configurations
+  with classic Powerpc architectures.
+
+  32-bit embedded platforms that are moved into arch/powerpc using a
+  flattened device tree should adopt the merged tree practice of
+  setting ppc_md up dynamically, even though the kernel is currently
+  built with support for only a single platform at a time.  This allows
+  unification of the setup code, and will make it easier to go to a
+  multiple-platform-support model in the future.
+
+NOTE: I believe the above will be true once Ben's done with the merge
+of the boot sequences.... someone speak up if this is wrong!
+
+  To add a 32-bit embedded platform support, follow the instructions
+  for 64-bit platforms above, with the exception that the Kconfig
+  option should be set up such that the kernel builds exclusively for
+  the platform selected.  The processor type for the platform should
+  enable another config option to select the specific board
+  supported.
+
+NOTE: If ben doesn't merge the setup files, may need to change this to
+point to setup_32.c
+
+
+   I will describe later the boot process and various callbacks that
+   your platform should implement.
+
+
+II - The DT block format
+========================
+
+
+This chapter defines the actual format of the flattened device-tree
+passed to the kernel. The actual content of it and kernel requirements
+are described later. You can find example of code manipulating that
+format in various places, including arch/powerpc/kernel/prom_init.c
+which will generate a flattened device-tree from the Open Firmware
+representation, or the fs2dt utility which is part of the kexec tools
+which will generate one from a filesystem representation. It is
+expected that a bootloader like uboot provides a bit more support,
+that will be discussed later as well.
+
+Note: The block has to be in main memory. It has to be accessible in
+both real mode and virtual mode with no mapping other than main
+memory. If you are writing a simple flash bootloader, it should copy
+the block to RAM before passing it to the kernel.
+
+
+1) Header
+---------
+
+   The kernel is entered with r3 pointing to an area of memory that is
+   roughtly described in include/asm-powerpc/prom.h by the structure
+   boot_param_header:
+
+struct boot_param_header {
+        u32     magic;                  /* magic word OF_DT_HEADER */
+        u32     totalsize;              /* total size of DT block */
+        u32     off_dt_struct;          /* offset to structure */
+        u32     off_dt_strings;         /* offset to strings */
+        u32     off_mem_rsvmap;         /* offset to memory reserve map
+*/
+        u32     version;                /* format version */
+        u32     last_comp_version;      /* last compatible version */
+
+        /* version 2 fields below */
+        u32     boot_cpuid_phys;        /* Which physical CPU id we're
+                                           booting on */
+        /* version 3 fields below */
+        u32     size_dt_strings;        /* size of the strings block */
+};
+
+   Along with the constants:
+
+/* Definitions used by the flattened device tree */
+#define OF_DT_HEADER            0xd00dfeed      /* 4: version,
+						   4: total size */
+#define OF_DT_BEGIN_NODE        0x1             /* Start node: full name
+*/
+#define OF_DT_END_NODE          0x2             /* End node */
+#define OF_DT_PROP              0x3             /* Property: name off,
+                                                   size, content */
+#define OF_DT_END               0x9
+
+   All values in this header are in big endian format, the various
+   fields in this header are defined more precisely below. All
+   "offset" values are in bytes from the start of the header; that is
+   from the value of r3.
+
+   - magic
+
+     This is a magic value that "marks" the beginning of the
+     device-tree block header. It contains the value 0xd00dfeed and is
+     defined by the constant OF_DT_HEADER
+
+   - totalsize
+
+     This is the total size of the DT block including the header. The
+     "DT" block should enclose all data structures defined in this
+     chapter (who are pointed to by offsets in this header). That is,
+     the device-tree structure, strings, and the memory reserve map.
+
+   - off_dt_struct
+
+     This is an offset from the beginning of the header to the start
+     of the "structure" part the device tree. (see 2) device tree)
+
+   - off_dt_strings
+
+     This is an offset from the beginning of the header to the start
+     of the "strings" part of the device-tree
+
+   - off_mem_rsvmap
+
+     This is an offset from the beginning of the header to the start
+     of the reserved memory map. This map is a list of pairs of 64
+     bit integers. Each pair is a physical address and a size. The
+
+     list is terminated by an entry of size 0. This map provides the
+     kernel with a list of physical memory areas that are "reserved"
+     and thus not to be used for memory allocations, especially during
+     early initialization. The kernel needs to allocate memory during
+     boot for things like un-flattening the device-tree, allocating an
+     MMU hash table, etc... Those allocations must be done in such a
+     way to avoid overriding critical things like, on Open Firmware
+     capable machines, the RTAS instance, or on some pSeries, the TCE
+     tables used for the iommu. Typically, the reserve map should
+     contain _at least_ this DT block itself (header,total_size). If
+     you are passing an initrd to the kernel, you should reserve it as
+     well. You do not need to reserve the kernel image itself. The map
+     should be 64 bit aligned.
+
+   - version
+
+     This is the version of this structure. Version 1 stops
+     here. Version 2 adds an additional field boot_cpuid_phys.
+     Version 3 adds the size of the strings block, allowing the kernel
+     to reallocate it easily at boot and free up the unused flattened
+     structure after expansion. Version 16 introduces a new more
+     "compact" format for the tree itself that is however not backward
+     compatible. You should always generate a structure of the highest
+     version defined at the time of your implementation. Currently
+     that is version 16, unless you explicitely aim at being backward
+     compatible.
+
+   - last_comp_version
+
+     Last compatible version. This indicates down to what version of
+     the DT block you are backward compatible. For example, version 2
+     is backward compatible with version 1 (that is, a kernel build
+     for version 1 will be able to boot with a version 2 format). You
+     should put a 1 in this field if you generate a device tree of
+     version 1 to 3, or 0x10 if you generate a tree of version 0x10
+     using the new unit name format.
+
+   - boot_cpuid_phys
+
+     This field only exist on version 2 headers. It indicate which
+     physical CPU ID is calling the kernel entry point. This is used,
+     among others, by kexec. If you are on an SMP system, this value
+     should match the content of the "reg" property of the CPU node in
+     the device-tree corresponding to the CPU calling the kernel entry
+     point (see further chapters for more informations on the required
+     device-tree contents)
+
+
+   So the typical layout of a DT block (though the various parts don't
+   need to be in that order) looks like this (addresses go from top to
+   bottom):
+
+
+             ------------------------------
+       r3 -> |  struct boot_param_header  |
+             ------------------------------
+             |      (alignment gap) (*)   |
+             ------------------------------
+             |      memory reserve map    |

+             ------------------------------

+      -----> ------------------------------
+      |
+      |
+      --- (r3 + totalsize)
+
+  (*) The alignment gaps are not necessarily present; their presence
+      and size are dependent on the various alignment requirements of
+      the individual data blocks.
+
+
+2) Device tree generalities
+---------------------------
+
+This device-tree itself is separated in two different blocks, a
+structure block and a strings block. Both need to be aligned to a 4
+byte boundary.
+
+First, let's quickly describe the device-tree concept before detailing
+the storage format. This chapter does _not_ describe the detail of the
+required types of nodes & properties for the kernel, this is done
+later in chapter III.
+
+The device-tree layout is strongly inherited from the definition of
+the Open Firmware IEEE 1275 device-tree. It's basically a tree of
+nodes, each node having two or more named properties. A property can
+have a value or not.
+
+It is a tree, so each node has one and only one parent except for the
+root node who has no parent.
+
+A node has 2 names. The actual node name is generally contained in a
+property of type "name" in the node property list whose value is a
+zero terminated string and is mandatory for version 1 to 3 of the
+format definition (as it is in Open Firmware). Version 0x10 makes it
+optional as it can generate it from the unit name defined below.
+
+There is also a "unit name" that is used to differenciate nodes with
+the same name at the same level, it is usually made of the node
+name's, the "@" sign, and a "unit address", which definition is
+specific to the bus type the node sits on.
+
+The unit name doesn't exist as a property per-se but is included in
+the device-tree structure. It is typically used to represent "path" in
+the device-tree. More details about the actual format of these will be
+below.
+
+The kernel powerpc generic code does not make any formal use of the
+unit address (though some board support code may do) so the only real
+requirement here for the unit address is to ensure uniqueness of
+the node unit name at a given level of the tree. Nodes with no notion
+of address and no possible sibling of the same name (like /memory or
+/cpus) may omit the unit address in the context of this specification,
+or use the "@0" default unit address. The unit name is used to define
+a node "full path", which is the concatenation of all parent node
+unit names separated with "/".
+
+The root node doesn't have a defined name, and isn't required to have
+a name property either if you are using version 3 or earlier of the
+format. It also has no unit address (no @ symbol followed by a unit
+address). The root node unit name is thus an empty string. The full
+path to the root node is "/".
+
+Every node which actually represents an actual device (that is, a node
+which isn't only a virtual "container" for more nodes, like "/cpus"
+is) is also required to have a "device_type" property indicating the
+type of node .
+
+Finally, every node that can be referenced from a property in another
+node is required to have a "linux,phandle" property. Real open
+firmware implementations provide a unique "phandle" value for every
+node that the "prom_init()" trampoline code turns into
+"linux,phandle" properties. However, this is made optional if the
+flattened device tree is used directly. An example of a node
+referencing another node via "phandle" is when laying out the
+interrupt tree which will be described in a further version of this
+document.
+
+This "linux, phandle" property is a 32 bit value that uniquely
+identifies a node. You are free to use whatever values or system of
+values, internal pointers, or whatever to generate these, the only
+requirement is that every node for which you provide that property has
+a unique value for it.
+
+Here is an example of a simple device-tree. In this example, an "o"
+designates a node followed by the node unit name. Properties are
+presented with their name followed by their content. "content"
+represents an ASCII string (zero terminated) value, while <content>
+represents a 32 bit hexadecimal value. The various nodes in this
+example will be discussed in a later chapter. At this point, it is
+only meant to give you a idea of what a device-tree looks like. I have
+purposefully kept the "name" and "linux,phandle" properties which
+aren't necessary in order to give you a better idea of what the tree
+looks like in practice.
+
+  / o device-tree
+      |- name = "device-tree"
+      |- model = "MyBoardName"
+      |- compatible = "MyBoardFamilyName"
+      |- #address-cells = <2>
+      |- #size-cells = <2>
+      |- linux,phandle = <0>
+      |
+      o cpus
+      | | - name = "cpus"
+      | | - linux,phandle = <1>
+      | | - #address-cells = <1>
+      | | - #size-cells = <0>
+      | |
+      | o PowerPC,970@0
+      |   |- name = "PowerPC,970"
+      |   |- device_type = "cpu"
+      |   |- reg = <0>
+      |   |- clock-frequency = <5f5e1000>
+      |   |- linux,boot-cpu
+      |   |- linux,phandle = <2>
+      |
+      o memory@0
+      | |- name = "memory"
+      | |- device_type = "memory"
+      | |- reg = <00000000 00000000 00000000 20000000>
+      | |- linux,phandle = <3>
+      |
+      o chosen
+        |- name = "chosen"
+        |- bootargs = "root=/dev/sda2"
+        |- linux,platform = <00000600>
+        |- linux,phandle = <4>
+
+This tree is almost a minimal tree. It pretty much contains the
+minimal set of required nodes and properties to boot a linux kernel;
+that is, some basic model informations at the root, the CPUs, and the
+physical memory layout.  It also includes misc information passed
+through /chosen, like in this example, the platform type (mandatory)
+and the kernel command line arguments (optional).
+
+The /cpus/PowerPC,970@0/linux,boot-cpu property is an example of a
+property without a value. All other properties have a value. The
+significance of the #address-cells and #size-cells properties will be
+explained in chapter IV which defines precisely the required nodes and
+properties and their content.
+
+
+3) Device tree "structure" block
+
+The structure of the device tree is a linearized tree structure. The
+"OF_DT_BEGIN_NODE" token starts a new node, and the "OF_DT_END_NODE"
+ends that node definition. Child nodes are simply defined before
+"OF_DT_END_NODE" (that is nodes within the node). A 'token' is a 32
+bit value. The tree has to be "finished" with a OF_DT_END token
+
+Here's the basic structure of a single node:
+
+     * token OF_DT_BEGIN_NODE (that is 0x00000001)
+     * for version 1 to 3, this is the node full path as a zero
+       terminated string, starting with "/". For version 16 and later,
+       this is the node unit name only (or an empty string for the
+       root node)
+     * [align gap to next 4 bytes boundary]
+     * for each property:
+        * token OF_DT_PROP (that is 0x00000003)
+        * 32 bit value of property value size in bytes (or 0 of no
+     * value)
+        * 32 bit value of offset in string block of property name
+        * property value data if any
+        * [align gap to next 4 bytes boundary]
+     * [child nodes if any]
+     * token OF_DT_END_NODE (that is 0x00000002)
+
+So the node content can be summmarised as a start token, a full path,
+a list of properties, a list of child node and an end token. Every
+child node is a full node structure itself as defined above.
+
+4) Device tree 'strings" block
+
+In order to save space, property names, which are generally redundant,
+are stored separately in the "strings" block. This block is simply the
+whole bunch of zero terminated strings for all property names
+concatenated together. The device-tree property definitions in the
+structure block will contain offset values from the beginning of the
+strings block.
+
+
+III - Required content of the device tree
+=========================================
+
+WARNING: All "linux,*" properties defined in this document apply only
+to a flattened device-tree. If your platform uses a real
+implementation of Open Firmware or an implementation compatible with
+the Open Firmware client interface, those properties will be created
+by the trampoline code in the kernel's prom_init() file. For example,
+that's where you'll have to add code to detect your board model and
+set the platform number. However, when using the flatenned device-tree
+entry point, there is no prom_init() pass, and thus you have to
+provide those properties yourself.
+
+
+1) Note about cells and address representation
+----------------------------------------------
+
+The general rule is documented in the various Open Firmware
+documentations. If you chose to describe a bus with the device-tree
+and there exist an OF bus binding, then you should follow the
+specification. However, the kernel does not require every single
+device or bus to be described by the device tree.
+
+In general, the format of an address for a device is defined by the
+parent bus type, based on the #address-cells and #size-cells
+property. In the absence of such a property, the parent's parent
+values are used, etc... The kernel requires the root node to have
+those properties defining addresses format for devices directly mapped
+on the processor bus.
+
+Those 2 properties define 'cells' for representing an address and a
+size. A "cell" is a 32 bit number. For example, if both contain 2
+like the example tree given above, then an address and a size are both
+composed of 2 cells, and each is a 64 bit number (cells are
+concatenated and expected to be in big endian format). Another example
+is the way Apple firmware defines them, with 2 cells for an address
+and one cell for a size.  Most 32-bit implementations should define
+#address-cells and #size-cells to 1, which represents a 32-bit value.
+Some 32-bit processors allow for physical addresses greater than 32
+bits; these processors should define #address-cells as 2.
+
+"reg" properties are always a tuple of the type "address size" where
+the number of cells of address and size is specified by the bus
+#address-cells and #size-cells. When a bus supports various address
+spaces and other flags relative to a given address allocation (like
+prefetchable, etc...) those flags are usually added to the top level
+bits of the physical address. For example, a PCI physical address is
+made of 3 cells, the bottom two containing the actual address itself
+while the top cell contains address space indication, flags, and pci
+bus & device numbers.
+
+For busses that support dynamic allocation, it's the accepted practice
+to then not provide the address in "reg" (keep it 0) though while
+providing a flag indicating the address is dynamically allocated, and
+then, to provide a separate "assigned-addresses" property that
+contains the fully allocated addresses. See the PCI OF bindings for
+details.
+
+In general, a simple bus with no address space bits and no dynamic
+allocation is preferred if it reflects your hardware, as the existing
+kernel address parsing functions will work out of the box. If you
+define a bus type with a more complex address format, including things
+like address space bits, you'll have to add a bus translator to the
+prom_parse.c file of the recent kernels for your bus type.
+
+The "reg" property only defines addresses and sizes (if #size-cells
+is
+non-0) within a given bus. In order to translate addresses upward
+(that is into parent bus addresses, and possibly into cpu physical
+addresses), all busses must contain a "ranges" property. If the
+"ranges" property is missing at a given level, it's assumed that
+translation isn't possible. The format of the "ranges" proprety for a
+bus is a list of:
+
+	bus address, parent bus address, size
+
+"bus address" is in the format of the bus this bus node is defining,
+that is, for a PCI bridge, it would be a PCI address. Thus, (bus
+address, size) defines a range of addresses for child devices. "parent
+bus address" is in the format of the parent bus of this bus. For
+example, for a PCI host controller, that would be a CPU address. For a
+PCI<->ISA bridge, that would be a PCI address. It defines the base
+address in the parent bus where the beginning of that range is mapped.
+
+For a new 64 bit powerpc board, I recommend either the 2/2 format or
+Apple's 2/1 format which is slightly more compact since sizes usually
+fit in a single 32 bit word.   New 32 bit powerpc boards should use a
+1/1 format, unless the processor supports physical addresses greater
+than 32-bits, in which case a 2/1 format is recommended.
+
+
+2) Note about "compatible" properties
+-------------------------------------
+
+These properties are optional, but recommended in devices and the root
+node. The format of a "compatible" property is a list of concatenated
+zero terminated strings. They allow a device to express its
+compatibility with a family of similar devices, in some cases,
+allowing a single driver to match against several devices regardless
+of their actual names.
+
+3) Note about "name" properties
+-------------------------------
+
+While earlier users of Open Firmware like OldWorld macintoshes tended
+to use the actual device name for the "name" property, it's nowadays
+considered a good practice to use a name that is closer to the device
+class (often equal to device_type). For example, nowadays, ethernet
+controllers are named "ethernet", an additional "model" property
+defining precisely the chip type/model, and "compatible" property
+defining the family in case a single driver can driver more than one
+of these chips. However, the kernel doesn't generally put any
+restriction on the "name" property; it is simply considered good
+practice to follow the standard and its evolutions as closely as
+possible.
+
+Note also that the new format version 16 makes the "name" property
+optional. If it's absent for a node, then the node's unit name is then
+used to reconstruct the name. That is, the part of the unit name
+before the "@" sign is used (or the entire unit name if no "@" sign
+is present).
+
+4) Note about node and property names and character set
+-------------------------------------------------------
+
+While open firmware provides more flexibe usage of 8859-1, this
+specification enforces more strict rules. Nodes and properties should
+be comprised only of ASCII characters 'a' to 'z', '0' to
+'9', ',', '.', '_', '+', '#', '?', and '-'. Node names additionally
+allow uppercase characters 'A' to 'Z' (property names should be
+lowercase. The fact that vendors like Apple don't respect this rule is
+irrelevant here). Additionally, node and property names should always
+begin with a character in the range 'a' to 'z' (or 'A' to 'Z' for node
+names).
+
+The maximum number of characters for both nodes and property names
+is 31. In the case of node names, this is only the leftmost part of
+a unit name (the pure "name" property), it doesn't include the unit
+address which can extend beyond that limit.
+
+
+5) Required nodes and properties
+--------------------------------
+  These are all that are currently required. However, it is strongly
+  recommended that you expose PCI host bridges as documented in the
+  PCI binding to open firmware, and your interrupt tree as documented
+  in OF interrupt tree specification.
+
+  a) The root node
+
+  The root node requires some properties to be present:
+
+    - model : this is your board name/model
+    - #address-cells : address representation for "root" devices
+    - #size-cells: the size representation for "root" devices
+
+  Additionally, some recommended properties are:
+
+    - compatible : the board "family" generally finds its way here,
+      for example, if you have 2 board models with a similar layout,
+      that typically get driven by the same platform code in the
+      kernel, you would use a different "model" property but put a
+      value in "compatible". The kernel doesn't directly use that
+      value (see /chosen/linux,platform for how the kernel choses a
+      platform type) but it is generally useful.
+
+  The root node is also generally where you add additional properties
+  specific to your board like the serial number if any, that sort of
+  thing. it is recommended that if you add any "custom" property whose
+  name may clash with standard defined ones, you prefix them with your
+  vendor name and a comma.
+
+  b) The /cpus node
+
+  This node is the parent of all individual CPU nodes. It doesn't
+  have any specific requirements, though it's generally good practice
+  to have at least:
+
+               #address-cells = <00000001>
+               #size-cells    = <00000000>
+
+  This defines that the "address" for a CPU is a single cell, and has
+  no meaningful size. This is not necessary but the kernel will assume
+  that format when reading the "reg" properties of a CPU node, see
+  below
+
+  c) The /cpus/* nodes
+
+  So under /cpus, you are supposed to create a node for every CPU on
+  the machine. There is no specific restriction on the name of the
+  CPU, though It's common practice to call it PowerPC,<name>. For
+  example, Apple uses PowerPC,G5 while IBM uses PowerPC,970FX.
+
+  Required properties:
+
+    - device_type : has to be "cpu"
+    - reg : This is the physical cpu number, it's a single 32 bit cell
+      and is also used as-is as the unit number for constructing the
+      unit name in the full path. For example, with 2 CPUs, you would
+      have the full path:
+        /cpus/PowerPC,970FX@0
+        /cpus/PowerPC,970FX@1
+      (unit addresses do not require leading zeroes)
+    - d-cache-line-size : one cell, L1 data cache line size in bytes
+    - i-cache-line-size : one cell, L1 instruction cache line size in
+      bytes
+    - d-cache-size : one cell, size of L1 data cache in bytes
+    - i-cache-size : one cell, size of L1 instruction cache in bytes
+    - linux, boot-cpu : Should be defined if this cpu is the boot cpu.
+
+  Recommended properties:
+
+    - timebase-frequency : a cell indicating the frequency of the
+      timebase in Hz. This is not directly used by the generic code,
+      but you are welcome to copy/paste the pSeries code for setting
+      the kernel timebase/decrementer calibration based on this
+      value.
+    - clock-frequency : a cell indicating the CPU core clock frequency
+      in Hz. A new property will be defined for 64 bit values, but if
+      your frequency is < 4Ghz, one cell is enough. Here as well as
+      for the above, the common code doesn't use that property, but
+      you are welcome to re-use the pSeries or Maple one. A future
+      kernel version might provide a common function for this.
+
+  You are welcome to add any property you find relevant to your board,
+  like some information about the mechanism used to soft-reset the
+  CPUs. For example, Apple puts the GPIO number for CPU soft reset
+  lines in there as a "soft-reset" property since they start secondary
+  CPUs by soft-resetting them.
+
+
+  d) the /memory node(s)
+
+  To define the physical memory layout of your board, you should
+  create one or more memory node(s). You can either create a single
+  node with all memory ranges in its reg property, or you can create
+  several nodes, as you wish. The unit address (@ part) used for the
+  full path is the address of the first range of memory defined by a
+  given node. If you use a single memory node, this will typically be
+  @0.
+
+  Required properties:
+
+    - device_type : has to be "memory"
+    - reg : This property contains all the physical memory ranges of
+      your board. It's a list of addresses/sizes concatenated
+      together, with the number of cells of each defined by the
+      #address-cells and #size-cells of the root node. For example,
+      with both of these properties beeing 2 like in the example given
+      earlier, a 970 based machine with 6Gb of RAM could typically
+      have a "reg" property here that looks like:
+
+      00000000 00000000 00000000 80000000
+      00000001 00000000 00000001 00000000
+
+      That is a range starting at 0 of 0x80000000 bytes and a range
+      starting at 0x100000000 and of 0x100000000 bytes. You can see
+      that there is no memory covering the IO hole between 2Gb and
+      4Gb. Some vendors prefer splitting those ranges into smaller
+      segments, but the kernel doesn't care.
+
+  e) The /chosen node
+
+  This node is a bit "special". Normally, that's where open firmware
+  puts some variable environment information, like the arguments, or
+  phandle pointers to nodes like the main interrupt controller, or the
+  default input/output devices.
+
+  This specification makes a few of these mandatory, but also defines
+  some linux-specific properties that would be normally constructed by
+  the prom_init() trampoline when booting with an OF client interface,
+  but that you have to provide yourself when using the flattened format.
+
+  Required properties:
+
+    - linux,platform : This is your platform number as assigned by the
+      architecture maintainers
+
+  Recommended properties:
+
+    - bootargs : This zero-terminated string is passed as the kernel
+      command line
+    - linux,stdout-path : This is the full path to your standard
+      console device if any. Typically, if you have serial devices on
+      your board, you may want to put the full path to the one set as
+      the default console in the firmware here, for the kernel to pick
+      it up as it's own default console. If you look at the funciton
+      set_preferred_console() in arch/ppc64/kernel/setup.c, you'll see
+      that the kernel tries to find out the default console and has
+      knowledge of various types like 8250 serial ports. You may want
+      to extend this function to add your own.
+    - interrupt-controller : This is one cell containing a phandle
+      value that matches the "linux,phandle" property of your main
+      interrupt controller node. May be used for interrupt routing.
+
+
+  Note that u-boot creates and fills in the chosen node for platforms
+  that use it.
+
+  f) the /soc<SOCname> node
+
+  This node is used to represent a system-on-a-chip (SOC) and must be
+  present if the processor is a SOC. The top-level soc node contains
+  information that is global to all devices on the SOC. The node name
+  should contain a unit address for the SOC, which is the base address
+  of the memory-mapped register set for the SOC. The name of an soc
+  node should start with "soc", and the remainder of the name should
+  represent the part number for the soc.  For example, the MPC8540's
+  soc node would be called "soc8540".
+
+  Required properties:
+
+    - device_type : Should be "soc"
+    - ranges : Should be defined as specified in 1) to describe the
+      translation of SOC addresses for memory mapped SOC registers.
+    - bus-frequency: Contains the bus frequency for the SOC node.
+      Typically, the value of this field is filled in by the boot
+      loader. 
+
+
+  Recommended properties:
+
+    - reg : This property defines the address and size of the
+      memory-mapped registers that are used for the SOC node itself.
+      It does not include the child device registers - these will be
+      defined inside each child node.  The address specified in the
+      "reg" property should match the unit address of the SOC node.
+    - #address-cells : Address representation for "soc" devices.  The
+      format of this field may vary depending on whether or not the
+      device registers are memory mapped.  For memory mapped
+      registers, this field represents the number of cells needed to
+      represent the address of the registers.  For SOCs that do not
+      use MMIO, a special address format should be defined that
+      contains enough cells to represent the required information.
+      See 1) above for more details on defining #address-cells.
+    - #size-cells : Size representation for "soc" devices
+    - #interrupt-cells : Defines the width of cells used to represent
+       interrupts.  Typically this value is <2>, which includes a
+       32-bit number that represents the interrupt number, and a
+       32-bit number that represents the interrupt sense and level.
+       This field is only needed if the SOC contains an interrupt
+       controller.
+
+  The SOC node may contain child nodes for each SOC device that the
+  platform uses.  Nodes should not be created for devices which exist
+  on the SOC but are not used by a particular platform. See chapter VI
+  for more information on how to specify devices that are part of an
+SOC.
+
+  Example SOC node for the MPC8540:
+
+	soc8540@e0000000 {
+		#address-cells = <1>;
+		#size-cells = <1>;
+		#interrupt-cells = <2>;
+		device_type = "soc";
+		ranges = <00000000 e0000000 00100000>
+		reg = <e0000000 00003000>;
+		bus-frequency = <0>;
+	}
+
+
+
+IV - "dtc", the device tree compiler
+====================================
+
+
+dtc source code can be found at
+<http://ozlabs.org/~dgibson/dtc/dtc.tar.gz>
+
+WARNING: This version is still in early development stage; the
+resulting device-tree "blobs" have not yet been validated with the
+kernel. The current generated bloc lacks a useful reserve map (it will
+be fixed to generate an empty one, it's up to the bootloader to fill
+it up) among others. The error handling needs work, bugs are lurking,
+etc...
+
+dtc basically takes a device-tree in a given format and outputs a
+device-tree in another format. The currently supported formats are:
+
+  Input formats:
+  -------------
+
+     - "dtb": "blob" format, that is a flattened device-tree block
+       with
+        header all in a binary blob.
+     - "dts": "source" format. This is a text file containing a
+       "source" for a device-tree. The format is defined later in this
+        chapter.
+     - "fs" format. This is a representation equivalent to the
+        output of /proc/device-tree, that is nodes are directories and
+	properties are files
+
+ Output formats:
+ ---------------
+
+     - "dtb": "blob" format
+     - "dts": "source" format
+     - "asm": assembly language file. This is a file that can be
+       sourced by gas to generate a device-tree "blob". That file can
+       then simply be added to your Makefile. Additionally, the
+       assembly file exports some symbols that can be use
+
+
+The syntax of the dtc tool is
+
+    dtc [-I <input-format>] [-O <output-format>]
+        [-o output-filename] [-V output_version] input_filename
+
+
+The "output_version" defines what versio of the "blob" format will be
+generated. Supported versions are 1,2,3 and 16. The default is
+currently version 3 but that may change in the future to version 16.
+
+Additionally, dtc performs various sanity checks on the tree, like the
+uniqueness of linux,phandle properties, validity of strings, etc...
+
+The format of the .dts "source" file is "C" like, supports C and C++
+style commments.
+
+/ {
+}
+
+The above is the "device-tree" definition. It's the only statement
+supported currently at the toplevel.
+
+/ {
+  property1 = "string_value";	/* define a property containing a 0
+                                 * terminated string
+				 */
+
+  property2 = <1234abcd>;	/* define a property containing a
+                                 * numerical 32 bits value (hexadecimal)
+				 */
+
+  property3 = <12345678 12345678 deadbeef>;
+                                /* define a property containing 3
+                                 * numerical 32 bits values (cells) in
+                                 * hexadecimal
+				 */
+  property4 = [0a 0b 0c 0d de ea ad be ef];
+                                /* define a property whose content is
+                                 * an arbitrary array of bytes
+                                 */
+
+  childnode@addresss {	/* define a child node named "childnode"
+                                 * whose unit name is "childnode at
+				 * address"
+                                 */
+
+    childprop = "hello\n";      /* define a property "childprop" of
+                                 * childnode (in this case, a string)
+                                 */
+  };
+};
+
+Nodes can contain other nodes etc... thus defining the hierarchical
+structure of the tree.
+
+Strings support common escape sequences from C: "\n", "\t", "\r",
+"\(octal value)", "\x(hex value)".
+
+It is also suggested that you pipe your source file through cpp (gcc
+preprocessor) so you can use #include's, #define for constants, etc...
+
+Finally, various options are planned but not yet implemented, like
+automatic generation of phandles, labels (exported to the asm file so
+you can point to a property content and change it easily from whatever
+you link the device-tree with), label or path instead of numeric value
+in some cells to "point" to a node (replaced by a phandle at compile
+time), export of reserve map address to the asm file, ability to
+specify reserve map content at compile time, etc...
+
+We may provide a .h include file with common definitions of that
+proves useful for some properties (like building PCI properties or
+interrupt maps) though it may be better to add a notion of struct
+definitions to the compiler...
+
+
+V - Recommendations for a bootloader
+====================================
+
+
+Here are some various ideas/recommendations that have been proposed
+while all this has been defined and implemented.
+
+  - The bootloader may want to be able to use the device-tree itself
+    and may want to manipulate it (to add/edit some properties,
+    like physical memory size or kernel arguments). At this point, 2
+    choices can be made. Either the bootloader works directly on the
+    flattened format, or the bootloader has its own internal tree
+    representation with pointers (similar to the kernel one) and
+    re-flattens the tree when booting the kernel. The former is a bit
+    more difficult to edit/modify, the later requires probably a bit
+    more code to handle the tree structure. Note that the structure
+    format has been designed so it's relatively easy to "insert"
+    properties or nodes or delete them by just memmoving things
+    around. It contains no internal offsets or pointers for this
+    purpose.
+
+  - An example of code for iterating nodes & retreiving properties
+    directly from the flattened tree format can be found in the kernel
+    file arch/ppc64/kernel/prom.c, look at scan_flat_dt() function,
+    it's usage in early_init_devtree(), and the corresponding various
+    early_init_dt_scan_*() callbacks. That code can be re-used in a
+    GPL bootloader, and as the author of that code, I would be happy
+    do discuss possible free licencing to any vendor who wishes to
+    integrate all or part of this code into a non-GPL bootloader.
+
+
+
+VI - System-on-a-chip devices and nodes
+=======================================
+
+Many companies are now starting to develop system-on-a-chip
+processors, where the processor core (cpu) and many peripheral devices
+exist on a single piece of silicon.  For these SOCs, an SOC node
+should be used that defines child nodes for the devices that make
+up the SOC. While platforms are not required to use this model in
+order to boot the kernel, it is highly encouraged that all SOC
+implementations define as complete a flat-device-tree as possible to
+describe the devices on the SOC.  This will allow for the
+genericization of much of the kernel code.
+
+
+1) Defining child nodes of an SOC
+---------------------------------
+
+Each device that is part of an SOC may have its own node entry inside
+the SOC node.  For each device that is included in the SOC, the unit
+address property represents the address offset for this device's
+memory-mapped registers in the parent's address space.  The parent's
+address space is defined by the "ranges" property in the top-level soc
+node. The "reg" property for each node that exists directly under the
+SOC node should contain the address mapping from the child address space
+to the parent SOC address space and the size of the device's
+memory-mapped register file.
+
+For many devices that may exist inside an SOC, there are predefined
+specifications for the format of the device tree node.  All SOC child
+nodes should follow these specifications, except where noted in this
+document.
+
+See appendix A for an example partial SOC node definition for the
+MPC8540.
+
+
+2) Specifying interrupt information for SOC devices
+---------------------------------------------------
+
+Each device that is part of an SOC and which generates interrupts
+should have the following properties:
+
+	- interrupt-parent : contains the phandle of the interrupt
+          controller which handles interrupts for this device
+	- interrupts : a list of tuples representing the interrupt
+          number and the interrupt sense and level for each interupt
+          for this device.
+
+This information is used by the kernel to build the interrupt table
+for the interrupt controllers in the system.
+
+Sense and level information should be encoded as follows:
+
+   Devices connected to openPIC-compatible controllers should encode
+   sense and polarity as follows:
+
+	0 = high to low edge sensitive type enabled
+	1 = active low level sensitive type enabled
+	2 = low to high edge sensitive type enabled
+	3 = active high level sensitive type enabled
+
+   ISA PIC interrupt controllers should adhere to the ISA PIC
+   encodings listed below:
+
+	0 =  active low level sensitive type enabled
+	1 =  active high level sensitive type enabled
+	2 =  high to low edge sensitive type enabled
+	3 =  low to high edge sensitive type enabled
+
+
+
+3) Representing devices without a current OF specification
+----------------------------------------------------------
+
+Currently, there are many devices on SOCs that do not have a standard
+representation pre-defined as part of the open firmware
+specifications, mainly because the boards that contain these SOCs are
+not currently booted using open firmware.   This section contains
+descriptions for the SOC devices for which new nodes have been
+defined; this list will expand as more and more SOC-containing
+platforms are moved over to use the flattened-device-tree model.
+
+  a) MDIO IO device
+
+  The MDIO is a bus to which the PHY devices are connected.  For each
+  device that exists on this bus, a child node should be created.  See
+  the definition of the PHY node below for an example of how to define
+  a PHY.
+
+  Required properties:
+    - reg : Offset and length of the register set for the device
+    - device_type : Should be "mdio"
+    - compatible : Should define the compatible device type for the
+      mdio.  Currently, this is most likely to be "gianfar"
+
+  Example:
+
+	mdio@24520 {
+		reg = <24520 20>;
+		device_type = "mdio"; 
+		compatible = "gianfar";
+
+		ethernet-phy@0 {
+			......
+		};
+	};
+
+
+  b) Gianfar-compatible ethernet nodes
+
+  Required properties:
+
+    - device_type : Should be "network"
+    - model : Model of the device.  Can be "TSEC", "eTSEC", or "FEC"
+    - compatible : Should be "gianfar"
+    - reg : Offset and length of the register set for the device
+    - address : List of bytes representing the ethernet address of
+      this controller
+    - interrupts : <a b> where a is the interrupt number and b is a
+      field that represents an encoding of the sense and level
+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt
+      controller you have.
+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+    - phy-handle : The phandle for the PHY connected to this ethernet
+      controller.
+
+  Example:
+
+	ethernet@24000 {
+		#size-cells = <0>;
+		device_type = "network";
+		model = "TSEC";
+		compatible = "gianfar";
+		reg = <24000 1000>;
+		address = [ 00 E0 0C 00 73 00 ];
+		interrupts = <d 3 e 3 12 3>;
+		interrupt-parent = <40000>;
+		phy-handle = <2452000>
+	};
+
+
+
+   c) PHY nodes
+
+   Required properties:
+
+    - device_type : Should be "ethernet-phy"
+    - interrupts : <a b> where a is the interrupt number and b is a
+      field that represents an encoding of the sense and level
+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt
+      controller you have.
+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+    - reg : The ID number for the phy, usually a small integer
+    - linux,phandle :  phandle for this node; likely referenced by an
+      ethernet controller node.
+
+
+   Example:
+
+	ethernet-phy@0 {
+		linux,phandle = <2452000>
+		interrupt-parent = <40000>;
+		interrupts = <35 1>;
+		reg = <0>;
+		device_type = "ethernet-phy";
+	};
+
+
+   d) Interrupt controllers
+
+   Some SOC devices contain interrupt controllers that are different
+   from the standard Open PIC specification.  The SOC device nodes for
+   these types of controllers should be specified just like a standard
+   OpenPIC controller.  Sense and level information should be encoded
+   as specified in section 2) of this chapter for each device that
+   specifies an interrupt.
+
+   Example :
+
+	pic@40000 {
+		linux,phandle = <40000>;
+		clock-frequency = <0>;
+		interrupt-controller;
+		#address-cells = <0>;
+		reg = <40000 40000>;
+		built-in;
+		compatible = "chrp,open-pic";
+		device_type = "open-pic";
+		big-endian;
+	};
+
+
+   e) I2C
+
+   Required properties :
+
+    - device_type : Should be "i2c"
+    - reg : Offset and length of the register set for the device
+
+   Recommended properties :
+
+    - compatible : Should be "fsl-i2c" for parts compatible with
+      Freescale I2C specifications.
+    - interrupts : <a b> where a is the interrupt number and b is a
+      field that represents an encoding of the sense and level
+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt
+      controller you have.
+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+    - dfsrr : boolean; if defined, indicates that this I2C device has
+      a digital filter sampling rate register
+    - fsl5200-clocking : boolean; if defined, indicated that this device
+      uses the FSL 5200 clocking mechanism.
+
+   Example :
+
+	i2c@3000 {
+		interrupt-parent = <40000>;
+		interrupts = <1b 3>;
+		reg = <3000 18>;
+		device_type = "i2c";
+		compatible  = "fsl-i2c";
+		dfsrr;
+	};
+
+
+   f) Freescale SOC USB controllers
+
+   The device node for a USB controller that is part of a Freescale
+   SOC is as described in the document "Open Firmware Recommended
+   Practice : Universal Serial Bus" with the following modifications
+   and additions :  
+
+   Required properties :
+    - compatible : Should be "fsl-usb2-mph" for multi port host usb
+      controllers, or "fsl-usb2-dr" for dual role usb controllers
+    - phy_type : For multi port host usb controllers, should be one of
+      "ulpi", or "serial". For dual role usb controllers, should be
+      one of "ulpi", "utmi", "utmi_wide", or "serial".
+    - reg : Offset and length of the register set for the device
+    - port0 : boolean; if defined, indicates port0 is connected for
+      fsl-usb2-mph compatible controllers.  Either this property or
+      "port1" (or both) must be defined for "fsl-usb2-mph" compatible 
+      controllers.
+    - port1 : boolean; if defined, indicates port1 is connected for
+      fsl-usb2-mph compatible controllers.  Either this property or
+      "port0" (or both) must be defined for "fsl-usb2-mph" compatible 
+      controllers.
+
+   Recommended properties :
+    - interrupts : <a b> where a is the interrupt number and b is a
+      field that represents an encoding of the sense and level
+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt
+      controller you have.
+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+
+   Example multi port host usb controller device node : 
+	usb@22000 {
+	        device_type = "usb";
+		compatible = "fsl-usb2-mph";
+		reg = <22000 1000>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		interrupt-parent = <700>;
+		interrupts = <27 1>;
+		phy_type = "ulpi";
+		port0;
+		port1;
+	};
+
+   Example dual role usb controller device node : 
+	usb@23000 {
+		device_type = "usb";
+		compatible = "fsl-usb2-dr";
+		reg = <23000 1000>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		interrupt-parent = <700>;
+		interrupts = <26 1>;
+		phy = "ulpi";
+	};
+
+
+   More devices will be defined as this spec matures.
+
+
+Appendix A - Sample SOC node for MPC8540

+
+Note that the #address-cells and #size-cells for the SoC node
+in this example have been explicitly listed; these are likely
+not necessary as they are usually the same as the root node.

+3 Older Version   : 00.00.02.01 
+
+i.	New template defined to represent each family of controllers (identified by processor used). 
+	The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

+
+1) Overview
+-----------
+Most legacy operating system kernels support an abstraction of threads
+as multiple execution contexts within a process. These kernels provide
+special resources and mechanisms to maintain these "threads". The Linux
+kernel, in a clever and simple manner, does not make distinction
+between processes and "threads". The kernel allows processes to share
+resources and thus they can achieve legacy "threads" behavior without
+requiring additional data structures and mechanisms in the kernel. The
+power of implementing threads in this manner comes not only from
+its simplicity but also from allowing application programmers to work
+outside the confinement of all-or-nothing shared resources of legacy
+threads. On Linux, at the time of thread creation using the clone system
+call, applications can selectively choose which resources to share
+between threads.
+
+unshare system call adds a primitive to the Linux thread model that
+allows threads to selectively 'unshare' any resources that were being
+shared at the time of their creation. unshare was conceptualized by
+Al Viro in the August of 2000, on the Linux-Kernel mailing list, as part
+of the discussion on POSIX threads on Linux.  unshare augments the
+usefulness of Linux threads for applications that would like to control
+shared resources without creating a new process. unshare is a natural
+addition to the set of available primitives on Linux that implement
+the concept of process/thread as a virtual machine.
+
+2) Benefits
+-----------
+unshare would be useful to large application frameworks such as PAM
+where creating a new process to control sharing/unsharing of process
+resources is not possible. Since namespaces are shared by default
+when creating a new process using fork or clone, unshare can benefit
+even non-threaded applications if they have a need to disassociate
+from default shared namespace. The following lists two use-cases
+where unshare can be used.
+
+2.1 Per-security context namespaces
+-----------------------------------
+unshare can be used to implement polyinstantiated directories using
+the kernel's per-process namespace mechanism. Polyinstantiated directories,
+such as per-user and/or per-security context instance of /tmp, /var/tmp or
+per-security context instance of a user's home directory, isolate user
+processes when working with these directories. Using unshare, a PAM
+module can easily setup a private namespace for a user at login.
+Polyinstantiated directories are required for Common Criteria certification
+with Labeled System Protection Profile, however, with the availability
+of shared-tree feature in the Linux kernel, even regular Linux systems
+can benefit from setting up private namespaces at login and
+polyinstantiating /tmp, /var/tmp and other directories deemed
+appropriate by system administrators.
+
+2.2 unsharing of virtual memory and/or open files
+-------------------------------------------------
+Consider a client/server application where the server is processing
+client requests by creating processes that share resources such as
+virtual memory and open files. Without unshare, the server has to
+decide what needs to be shared at the time of creating the process
+which services the request. unshare allows the server an ability to
+disassociate parts of the context during the servicing of the
+request. For large and complex middleware application frameworks, this
+ability to unshare after the process was created can be very
+useful.
+
+3) Cost
+-------
+In order to not duplicate code and to handle the fact that unshare
+works on an active task (as opposed to clone/fork working on a newly
+allocated inactive task) unshare had to make minor reorganizational
+changes to copy_* functions utilized by clone/fork system call.
+There is a cost associated with altering existing, well tested and
+stable code to implement a new feature that may not get exercised
+extensively in the beginning. However, with proper design and code
+review of the changes and creation of an unshare test for the LTP
+the benefits of this new feature can exceed its cost.
+
+4) Requirements
+---------------
+unshare reverses sharing that was done using clone(2) system call,
+so unshare should have a similar interface as clone(2). That is,
+since flags in clone(int flags, void *stack) specifies what should
+be shared, similar flags in unshare(int flags) should specify
+what should be unshared. Unfortunately, this may appear to invert
+the meaning of the flags from the way they are used in clone(2).
+However, there was no easy solution that was less confusing and that
+allowed incremental context unsharing in future without an ABI change.
+
+unshare interface should accommodate possible future addition of
+new context flags without requiring a rebuild of old applications.
+If and when new context flags are added, unshare design should allow
+incremental unsharing of those resources on an as needed basis.
+
+5) Functional Specification
+---------------------------
+NAME
+	unshare - disassociate parts of the process execution context
+
+SYNOPSIS
+	#include <sched.h>
+
+	int unshare(int flags);
+
+DESCRIPTION
+	unshare allows a process to disassociate parts of its execution
+	context that are currently being shared with other processes. Part
+	of execution context, such as the namespace, is shared by default
+	when a new process is created using fork(2), while other parts,
+	such as the virtual memory, open file descriptors, etc, may be
+	shared by explicit request to share them when creating a process
+	using clone(2).
+
+	The main use of unshare is to allow a process to control its
+	shared execution context without creating a new process.
+
+	The flags argument specifies one or bitwise-or'ed of several of
+	the following constants.
+
+	CLONE_FS
+		If CLONE_FS is set, file system information of the caller
+		is disassociated from the shared file system information.
+
+	CLONE_FILES
+		If CLONE_FILES is set, the file descriptor table of the
+		caller is disassociated from the shared file descriptor
+		table.
+
+	CLONE_NEWNS
+		If CLONE_NEWNS is set, the namespace of the caller is
+		disassociated from the shared namespace.
+
+	CLONE_VM
+		If CLONE_VM is set, the virtual memory of the caller is
+		disassociated from the shared virtual memory.
+
+RETURN VALUE
+	On success, zero returned. On failure, -1 is returned and errno is
+
+ERRORS
+	EPERM	CLONE_NEWNS was specified by a non-root process (process
+		without CAP_SYS_ADMIN).
+
+	ENOMEM	Cannot allocate sufficient memory to copy parts of caller's
+		context that need to be unshared.
+
+	EINVAL	Invalid flag was specified as an argument.
+
+CONFORMING TO
+	The unshare() call is Linux-specific and  should  not be used
+	in programs intended to be portable.
+
+SEE ALSO
+	clone(2), fork(2)
+
+6) High Level Design
+--------------------
+Depending on the flags argument, the unshare system call allocates
+appropriate process context structures, populates it with values from
+the current shared version, associates newly duplicated structures
+with the current task structure and releases corresponding shared
+versions. Helper functions of clone (copy_*) could not be used
+directly by unshare because of the following two reasons.
+  1) clone operates on a newly allocated not-yet-active task
+     structure, where as unshare operates on the current active
+     task. Therefore unshare has to take appropriate task_lock()
+     before associating newly duplicated context structures
+  2) unshare has to allocate and duplicate all context structures
+     that are being unshared, before associating them with the
+     current task and releasing older shared structures. Failure
+     do so will create race conditions and/or oops when trying
+     to backout due to an error. Consider the case of unsharing
+     both virtual memory and namespace. After successfully unsharing
+     vm, if the system call encounters an error while allocating
+     new namespace structure, the error return code will have to
+     reverse the unsharing of vm. As part of the reversal the
+     system call will have to go back to older, shared, vm
+     structure, which may not exist anymore.
+
+Therefore code from copy_* functions that allocated and duplicated
+current context structure was moved into new dup_* functions. Now,
+copy_* functions call dup_* functions to allocate and duplicate
+appropriate context structures and then associate them with the
+task structure that is being constructed. unshare system call on
+the other hand performs the following:
+  1) Check flags to force missing, but implied, flags
+  2) For each context structure, call the corresponding unshare
+     helper function to allocate and duplicate a new context
+     structure, if the appropriate bit is set in the flags argument.
+  3) If there is no error in allocation and duplication and there
+     are new context structures then lock the current task structure,
+     associate new context structures with the current task structure,
+     and release the lock on the current task structure.
+  4) Appropriately release older, shared, context structures.
+
+7) Low Level Design
+-------------------
+Implementation of unshare can be grouped in the following 4 different
+items:
+  a) Reorganization of existing copy_* functions
+  b) unshare system call service function
+  c) unshare helper functions for each different process context
+  d) Registration of system call number for different architectures
+
+  7.1) Reorganization of copy_* functions
+       Each copy function such as copy_mm, copy_namespace, copy_files,
+       etc, had roughly two components. The first component allocated
+       and duplicated the appropriate structure and the second component
+       linked it to the task structure passed in as an argument to the copy
+       function. The first component was split into its own function.
+       These dup_* functions allocated and duplicated the appropriate
+       context structure. The reorganized copy_* functions invoked
+       their corresponding dup_* functions and then linked the newly
+       duplicated structures to the task structure with which the
+       copy function was called.
+
+  7.2) unshare system call service function
+       * Check flags
+	 Force implied flags. If CLONE_THREAD is set force CLONE_VM.
+	 If CLONE_VM is set, force CLONE_SIGHAND. If CLONE_SIGHAND is
+	 set and signals are also being shared, force CLONE_THREAD. If
+	 CLONE_NEWNS is set, force CLONE_FS.
+       * For each context flag, invoke the corresponding unshare_*
+	 helper routine with flags passed into the system call and a
+	 reference to pointer pointing the new unshared structure
+       * If any new structures are created by unshare_* helper
+	 functions, take the task_lock() on the current task,
+	 modify appropriate context pointers, and release the
+         task lock.
+       * For all newly unshared structures, release the corresponding
+         older, shared, structures.
+
+  7.3) unshare_* helper functions
+       For unshare_* helpers corresponding to CLONE_SYSVSEM, CLONE_SIGHAND,
+       and CLONE_THREAD, return -EINVAL since they are not implemented yet.
+       For others, check the flag value to see if the unsharing is
+       required for that structure. If it is, invoke the corresponding
+       dup_* function to allocate and duplicate the structure and return
+       a pointer to it.
+
+  7.4) Appropriately modify architecture specific code to register the
+       the new system call.
+
+8) Test Specification
+---------------------
+The test for unshare should test the following:
+  1) Valid flags: Test to check that clone flags for signal and
+	signal handlers, for which unsharing is not implemented
+	yet, return -EINVAL.
+  2) Missing/implied flags: Test to make sure that if unsharing
+	namespace without specifying unsharing of filesystem, correctly
+	unshares both namespace and filesystem information.
+  3) For each of the four (namespace, filesystem, files and vm)
+	supported unsharing, verify that the system call correctly
+	unshares the appropriate structure. Verify that unsharing
+	them individually as well as in combination with each
+	other works as expected.
+  4) Concurrent execution: Use shared memory segments and futex on
+	an address in the shm segment to synchronize execution of
+	about 10 threads. Have a couple of threads execute execve,
+	a couple _exit and the rest unshare with different combination
+	of flags. Verify that unsharing is performed as expected and
+	that there are no oops or hangs.
+
+9) Future Work
+--------------
+The current implementation of unshare does not allow unsharing of
+signals and signal handlers. Signals are complex to begin with and
+to unshare signals and/or signal handlers of a currently running
+process is even more complex. If in the future there is a specific
+need to allow unsharing of signals and/or signal handlers, it can
+be incrementally added to unshare without affecting legacy
+applications using unshare.

+
+4. Overview and features
+========================
+This driver supports the video interface of the devices mounting the ET61X151
+or ET61X251 PC Camera Controllers.
+
+It's worth to note that Etoms Electronics has never collaborated with the
+author during the development of this project; despite several requests,
+Etoms Electronics also refused to release enough detailed specifications of
+the video compression engine.
+
+The driver relies on the Video4Linux2 and USB core modules. It has been
+designed to run properly on SMP systems as well.
+
+The latest version of the ET61X[12]51 driver can be found at the following URL:
+http://www.linux-projects.org/
+
+Some of the features of the driver are:
+
+- full compliance with the Video4Linux2 API (see also "Notes for V4L2
+  application developers" paragraph);
+- available mmap or read/poll methods for video streaming through isochronous
+  data transfers;
+- automatic detection of image sensor;
+- support for any window resolutions and optional panning within the maximum
+  pixel area of image sensor;
+- image downscaling with arbitrary scaling factors from 1 and 2 in both
+  directions (see "Notes for V4L2 application developers" paragraph);
+- two different video formats for uncompressed or compressed data in low or
+  high compression quality (see also "Notes for V4L2 application developers"
+  paragraph);
+- full support for the capabilities of every possible image sensors that can
+  be connected to the ET61X[12]51 bridges, including, for istance, red, green,
+  blue and global gain adjustments and exposure control (see "Supported
+  devices" paragraph for details);
+- use of default color settings for sunlight conditions;
+- dynamic I/O interface for both ET61X[12]51 and image sensor control (see
+  "Optional device control through 'sysfs'" paragraph);
+- dynamic driver control thanks to various module parameters (see "Module
+  parameters" paragraph);
+- up to 64 cameras can be handled at the same time; they can be connected and
+  disconnected from the host many times without turning off the computer, if
+  the system supports hotplugging;
+- no known bugs.
+
+
+5. Module dependencies
+======================
+For it to work properly, the driver needs kernel support for Video4Linux and
+USB.
+
+The following options of the kernel configuration file must be enabled and
+corresponding modules must be compiled:
+
+	# Multimedia devices
+	#
+	CONFIG_VIDEO_DEV=m
+
+To enable advanced debugging functionality on the device through /sysfs:
+
+	# Multimedia devices
+	#
+	CONFIG_VIDEO_ADV_DEBUG=y
+
+	# USB support
+	#
+	CONFIG_USB=m
+
+In addition, depending on the hardware being used, the modules below are
+necessary:
+
+	# USB Host Controller Drivers
+	#
+	CONFIG_USB_EHCI_HCD=m
+	CONFIG_USB_UHCI_HCD=m
+	CONFIG_USB_OHCI_HCD=m
+
+And finally:
+
+	# USB Multimedia devices
+	#
+	CONFIG_USB_ET61X251=m
+
+
+6. Module loading
+=================
+To use the driver, it is necessary to load the "et61x251" module into memory
+after every other module required: "videodev", "usbcore" and, depending on
+the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd".
+
+Loading can be done as shown below:
+
+	[root@localhost home]# modprobe et61x251
+
+At this point the devices should be recognized. You can invoke "dmesg" to
+analyze kernel messages and verify that the loading process has gone well:
+
+	[user@localhost home]$ dmesg
+
+
+7. Module parameters
+====================
+Module parameters are listed below:
+-------------------------------------------------------------------------------
+Name:           video_nr
+Type:           short array (min = 0, max = 64)
+Syntax:         <-1|n[,...]>

+                You can specify up to 64 cameras this way.
+                For example:
+                video_nr=-1,2,-1 would assign minor number 2 to the second
+                registered camera and use auto for the first one and for every
+                other camera.
+Default:        -1

+8. Optional device control through "sysfs"
+==========================================
+If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
+it is possible to read and write both the ET61X[12]51 and the image sensor
+registers by using the "sysfs" filesystem interface.
+
+There are four files in the /sys/class/video4linux/videoX directory for each
+registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files
+control the ET61X[12]51 bridge, while the other two control the sensor chip.
+"reg" and "i2c_reg" hold the values of the current register index where the
+following reading/writing operations are addressed at through "val" and
+"i2c_val". Their use is not intended for end-users, unless you know what you
+are doing. Remember that you must be logged in as root before writing to them.
+
+As an example, suppose we were to want to read the value contained in the
+register number 1 of the sensor register table - which is usually the product
+identifier - of the camera registered as "/dev/video0":
+
+	[root@localhost #] cd /sys/class/video4linux/video0
+	[root@localhost #] echo 1 > i2c_reg
+	[root@localhost #] cat i2c_val
+
+Note that if the sensor registers can not be read, "cat" will fail.
+To avoid race conditions, all the I/O accesses to the files are serialized.
+
+
+9. Supported devices

+10. Notes for V4L2 application developers
+========================================
+This driver follows the V4L2 API specifications. In particular, it enforces two
+rules:
+
+- exactly one I/O method, either "mmap" or "read", is associated with each
+file descriptor. Once it is selected, the application must close and reopen the
+device to switch to the other I/O method;
+
+- although it is not mandatory, previously mapped buffer memory should always
+be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
+The same number of buffers as before will be allocated again to match the size
+of the new video frames, so you have to map the buffers again before any I/O
+attempts on them.
+
+Consistently with the hardware limits, this driver also supports image
+downscaling with arbitrary scaling factors from 1 and 2 in both directions.
+However, the V4L2 API specifications don't correctly define how the scaling
+factor can be chosen arbitrarily by the "negotiation" of the "source" and
+"target" rectangles. To work around this flaw, we have added the convention
+that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the
+scaling factor is restored to 1.
+
+This driver supports two different video formats: the first one is the "8-bit
+Sequential Bayer" format and can be used to obtain uncompressed video data
+from the device through the current I/O method, while the second one provides
+"raw" compressed video data (without frame headers not related to the
+compressed data). The current compression quality may vary from 0 to 1 and can
+be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP
+V4L2 ioctl's.

+Page migration
+--------------
+
+Page migration allows the moving of the physical location of pages between
+nodes in a numa system while the process is running. This means that the
+virtual addresses that the process sees do not change. However, the
+system rearranges the physical location of those pages.
+
+The main intend of page migration is to reduce the latency of memory access
+by moving pages near to the processor where the process accessing that memory
+is running.
+
+Page migration allows a process to manually relocate the node on which its
+pages are located through the MF_MOVE and MF_MOVE_ALL options while setting
+a new memory policy. The pages of process can also be relocated
+from another process using the sys_migrate_pages() function call. The
+migrate_pages function call takes two sets of nodes and moves pages of a
+process that are located on the from nodes to the destination nodes.
+
+Manual migration is very useful if for example the scheduler has relocated
+a process to a processor on a distant node. A batch scheduler or an
+administrator may detect the situation and move the pages of the process
+nearer to the new processor. At some point in the future we may have
+some mechanism in the scheduler that will automatically move the pages.
+
+Larger installations usually partition the system using cpusets into
+sections of nodes. Paul Jackson has equipped cpusets with the ability to
+move pages when a task is moved to another cpuset. This allows automatic
+control over locality of a process. If a task is moved to a new cpuset
+then also all its pages are moved with it so that the performance of the
+process does not sink dramatically (as is the case today).
+
+Page migration allows the preservation of the relative location of pages
+within a group of nodes for all migration techniques which will preserve a
+particular memory allocation pattern generated even after migrating a
+process. This is necessary in order to preserve the memory latencies.
+Processes will run with similar performance after migration.
+
+Page migration occurs in several steps. First a high level
+description for those trying to use migrate_pages() and then
+a low level description of how the low level details work.
+
+A. Use of migrate_pages()
+-------------------------
+
+1. Remove pages from the LRU.
+
+   Lists of pages to be migrated are generated by scanning over
+   pages and moving them into lists. This is done by
+   calling isolate_lru_page() or __isolate_lru_page().
+   Calling isolate_lru_page increases the references to the page
+   so that it cannot vanish under us.
+
+2. Generate a list of newly allocates page to move the contents
+   of the first list to.
+
+3. The migrate_pages() function is called which attempts
+   to do the migration. It returns the moved pages in the
+   list specified as the third parameter and the failed
+   migrations in the fourth parameter. The first parameter
+   will contain the pages that could still be retried.
+
+4. The leftover pages of various types are returned
+   to the LRU using putback_to_lru_pages() or otherwise
+   disposed of. The pages will still have the refcount as
+   increased by isolate_lru_pages()!
+
+B. Operation of migrate_pages()
+--------------------------------
+
+migrate_pages does several passes over its list of pages. A page is moved
+if all references to a page are removable at the time.
+
+Steps:
+
+1. Lock the page to be migrated
+
+2. Insure that writeback is complete.
+
+3. Make sure that the page has assigned swap cache entry if
+   it is an anonyous page. The swap cache reference is necessary
+   to preserve the information contain in the page table maps.
+
+4. Prep the new page that we want to move to. It is locked
+   and set to not being uptodate so that all accesses to the new
+   page immediately lock while we are moving references.
+
+5. All the page table references to the page are either dropped (file backed)
+   or converted to swap references (anonymous pages). This should decrease the
+   reference count.
+
+6. The radix tree lock is taken
+
+7. The refcount of the page is examined and we back out if references remain
+   otherwise we know that we are the only one referencing this page.
+
+8. The radix tree is checked and if it does not contain the pointer to this
+   page then we back out.
+
+9. The mapping is checked. If the mapping is gone then a truncate action may
+   be in progress and we back out.
+
+10. The new page is prepped with some settings from the old page so that accesses
+   to the new page will be discovered to have the correct settings.
+
+11. The radix tree is changed to point to the new page.
+
+12. The reference count of the old page is dropped because the reference has now
+    been removed.
+
+13. The radix tree lock is dropped.
+
+14. The page contents are copied to the new page.
+
+15. The remaining page flags are copied to the new page.
+
+16. The old page flags are cleared to indicate that the page does
+    not use any information anymore.
+
+17. Queued up writeback on the new page is triggered.
+
+18. If swap pte's were generated for the page then remove them again.
+
+19. The locks are dropped from the old and new page.
+
+20. The new page is moved to the LRU.

+ *
+ * 1) The following types are of fixed size for all targets (16/32/64):
+ *
+ * BOOLEAN      Logical boolean
+ *
+ * UINT8        8-bit  (1 byte) unsigned value

+ *
+ * INT16        16-bit (2 byte) signed value
+ * INT32        32-bit (4 byte) signed value
+ * INT64        64-bit (8 byte) signed value
+ *
+ * COMPILER_DEPENDENT_UINT64/INT64 - These types are defined in the
+ * compiler-dependent header(s) and were introduced because there is no common
+ * 64-bit integer type across the various compilation models, as shown in
+ * the table below.
+ *
+ * Datatype  LP64 ILP64 LLP64 ILP32 LP32 16bit
+ * char      8    8     8     8     8    8
+ * short     16   16    16    16    16   16
+ * _int32         32
+ * int       32   64    32    32    16   16
+ * long      64   64    32    32    32   32

+ *
+ * Note: ILP64 and LP32 are currently not supported.
+ *
+ *
+ * 2) These types represent the native word size of the target mode of the
+ * processor, and may be 16-bit, 32-bit, or 64-bit as required. They are
+ * usually used for memory allocation, efficient loop counters, and array
+ * indexes. The types are similar to the size_t type in the C library and are
+ * required because there is no C type that consistently represents the native
+ * data width.

+ *
+ * Hack:
+ *
+ *    Set the exiting tasks cpuset to the root cpuset (top_cpuset).
+ *
+ *    Don't leave a task unable to allocate memory, as that is an
+ *    accident waiting to happen should someone add a callout in
+ *    do_exit() after the cpuset_exit() call that might allocate.
+ *    If a task tries to allocate memory with an invalid cpuset,
+ *    it will oops in cpuset_update_task_memory_state().
+ *
+ *    We call cpuset_exit() while the task is still competent to
+ *    handle notify_on_release(), then leave the task attached to
+ *    the root cpuset (top_cpuset) for the remainder of its exit.
+ *
+ *    To do this properly, we would increment the reference count on
+ *    top_cpuset, and near the very end of the kernel/exit.c do_exit()
+ *    code we would add a second cpuset function call, to drop that
+ *    reference.  This would just create an unnecessary hot spot on
+ *    the top_cpuset reference count, to no avail.
+ *
+ *    Normally, holding a reference to a cpuset without bumping its
+ *    count is unsafe.   The cpuset could go away, or someone could
+ *    attach us to a different cpuset, decrementing the count on
+ *    the first cpuset that we never incremented.  But in this case,
+ *    top_cpuset isn't going away, and either task has PF_EXITING set,
+ *    which wards off any attach_task() attempts, or task is a failed
+ *    fork, never visible to attach_task.
+ *
+ *    Another way to do this would be to set the cpuset pointer
+ *    to NULL here, and check in cpuset_update_task_memory_state()
+ *    for a NULL pointer.  This hack avoids that NULL check, for no
+ *    cost (other than this way too long comment ;).
