alpha: remove LCA and APECS based machines
APECS is the DECchip 21071x chipset for the EV4 and EV45 generation, while LCA is the integrated I/O support on the corresponding low-cost alpha machines of that generation. All of these CPUs lack the BWX extension for byte and word access, so drop the chipset support and all associated machines. Acked-by: Paul E.

- An AVANTI *might* be an XL, and an XL has only 27 bits of ISA address
- that get passed through the PCI<->ISA bridge chip. So we've gotta use
- both windows to max out the physical memory we can DMA to. Sigh...
-
- If we try a window at 0 for 1GB as a work-around, we run into conflicts
- with ISA/PCI bus memory which can't be relocated, like VGA aperture and
- BIOS ROMs. So we must put the windows high enough to avoid these areas.
-
- We put window 1 at BUS 64Mb for 64Mb, mapping physical 0 to 64Mb-1,
- and window 2 at BUS 1Gb for 1Gb, mapping physical 0 to 1Gb-1.
- Yes, this does map 0 to 64Mb-1 twice, but only window 1 will actually
- be used for that range (via virt_to_bus()).
-
- Note that we actually fudge the window 1 maximum as 48Mb instead of 64Mb,
- to keep virt_to_bus() from returning an address in the first window, for
- a data area that goes beyond the 64Mb first DMA window. Sigh...
- The fudge factor MUST match with <asm/dma.h> MAX_DMA_ADDRESS, but
- we can't just use that here, because of header file looping... :-(
-
- Window 1 will be used for all DMA from the ISA bus; yes, that does
- limit what memory an ISA floppy or sound card or Ethernet can touch, but
- it's also a known limitation on other platforms as well. We use the
- same technique that is used on INTEL platforms with similar limitation:
- set MAX_DMA_ADDRESS and clear some pages' DMAable flags during mem_init().
- We trust that any ISA bus device drivers will *always* ask for DMAable
- memory explicitly via kmalloc()/get_free_pages() flags arguments.
-
- Note that most PCI bus devices' drivers do *not* explicitly ask for
- DMAable memory; they count on being able to DMA to any memory they
- get from kmalloc()/get_free_pages(). They will also use window 1 for
- any physical memory accesses below 64Mb; the rest will be handled by
- window 2, maxing out at 1Gb of memory. I trust this is enough... :-)
-
- We hope that the area before the first window is large enough so that
- there will be no overlap at the top end (64Mb). We *must* locate the
- PCI cards' memory just below window 1, so that there's still the
- possibility of being able to access it via SPARSE space. This is
- important for cards such as the Matrox Millennium, whose Xserver
- wants to access memory-mapped registers in byte and short lengths.
-
- Note that the XL is treated differently from the AVANTI, even though
- for most other things they are identical. It didn't seem reasonable to
- make the AVANTI support pay for the limitations of the XL. It is true,
- however, that an XL kernel will run on an AVANTI without problems.
-
- %%% All of this should be obviated by the ability to route
- everything through the iommu.

-/*
- * NOTE: The LCA uses a Host Address Extension (HAE) register to access
- * PCI addresses that are beyond the first 27 bits of address
- * space. Updating the HAE requires an external cycle (and
- * a memory barrier), which tends to be slow. Instead of updating
- * it on each sparse memory access, we keep the current HAE value
- * cached in variable cache_hae. Only if the cached HAE differs
- * from the desired HAE value do we actually updated HAE register.
- * The HAE register is preserved by the interrupt handler entry/exit
- * code, so this scheme works even in the presence of interrupts.
- *
- * Dense memory space doesn't require the HAE, but is restricted to
- * aligned 32 and 64 bit accesses. Special Cycle and Interrupt
- * Acknowledge cycles may also require the use of the HAE. The LCA
- * limits I/O address space to the bottom 24 bits of address space,
- * but this easily covers the 16 bit ISA I/O address space.
- */
-
-/*
- * NOTE 2! The memory operations do not set any memory barriers, as
- * it's not needed for cases like a frame buffer that is essentially
- * memory-like. You need to do them by hand if the operations depend
- * on ordering.
- *
- * Similarly, the port I/O operations do a "mb" only after a write
- * operation: if an mb is needed before (as in the case of doing
- * memory mapped I/O first, and then a port I/O operation to the same
- * device), it needs to be done by hand.
- *
- * After the above has bitten me 100 times, I'll give up and just do
- * the mb all the time, but right now I'm hoping this will work out.
- * Avoiding mb's may potentially be a noticeable speed improvement,
- * but I can't honestly say I've tested it.
- *
- * Handling interrupts that need to do mb's to synchronize to
- * non-interrupts is another fun race area. Don't do it (because if
- * you do, I'll have to do *everything* with interrupts disabled,
- * ugh).
