 * Description:  This register shows which regions are in the current   *
 * cell. If a region has its bit set in this register, then it uses     *
 * the Local Access protection in the directory instead of the          *
 * separate per-region protection (which would cause a small            *
 * performance penalty). In addition, writeback and write reply         *
 * commands from outside the current cell will always check the         *
 * directory protection before writing data to memory. Writeback and    *
 * write reply commands from inside the current cell will write         *
 * memory regardless of the protection value.                           *
 * This register is also used as the access-rights bit-vector for       *
 * most of the ASIC-special (HSpec) portion of the address space. It    *
 * covers the BDDIR, LREG, LBOOT, RREG, and RBOOT spaces. It does not   *
 * cover the UALIAS and BDECC spaces, as they are covered by the        *
 * protection in the directory. If a bit in the bit-vector is set,      *
 * the region corresponding to that bit has read/write permission on    *
 * these spaces. If the bit is clear, then that region has read-only    *
 * access to these spaces (except for LREG/RREG which have no access    *
 * when the bit is clear).                                              *
 * The granularity of a region is set by the REGION_SIZE register in    *
 * the NI local register space.                                         *
 * NOTE: This means that no processor outside the current cell can      *
 * write into the BDDIR, LREG, LBOOT, RREG, or RBOOT spaces.            *
 *                                                                      *

 * Description:  This register contains three sets of information.      *
 * The first set describes the size and configuration of DIMMs that     *
 * are plugged into a system, the second set controls which set of      *
 * protection checks are performed on each access and the third set     *
 * controls various DDR SDRAM timing parameters.                        *
 * In order to config a DIMM bank, three fields must be initialized:    *
 * BANK_SIZE, DRAM_WIDTH, and BANK_ENABLE. The BANK_SIZE field sets     *
 * the address range that the MD unit will accept for that DIMM bank.   *
 * All addresses larger than the specified size will return errors on   *
 * access. In order to read from a DIMM bank, Bedrock must know         *
 * whether or not the bank contains x4 or x8/x16 DRAM. The operating    *
 * system must query the System Controller for this information and     *
 * then set the DRAM_WIDTH field accordingly. The BANK_ENABLE field     *
 * can be used to individually enable the two physical banks located    *
 * on each DIMM bank.                                                   *
 * The contents of this register are preserved through soft-resets.     *
 *                                                                      *

 * Description:  This register contains the control for                 *
 * memory/directory refresh. Once the MEMORY_CONFIG register contains   *
 * the correct DIMM information, the hardware takes care of             *
 * refreshing all the banks in the system. Therefore, the value in      *
 * the counter threshold is corresponds exactly to the refresh value    *
 * required by the SDRAM parts (expressed in Bedrock clock cycles).     *
 * The refresh will execute whenever there is a free cycle and there    *
 * are still banks that have not been refreshed in the current          *
 * window. If the window expires with banks still waiting to be         *
 * refreshed, all other transactions are halted until the banks are     *
 * refreshed.                                                           *
 * The upper order bit contains an enable, which may be needed for      *
 * correct initialization of the DIMMs (according to the specs, the     *
 * first operation to the DIMMs should be a mode register write, not    *
 * a refresh, so this bit is cleared on reset) and is also useful for   *
 * diagnostic purposes.                                                 *
 * For the SDRAM parts used by Bedrock, 4096 refreshes need to be       *
 * issued during every 64 ms window, resulting in a refresh threshold   *
 * of 3125 Bedrock cycles.                                              *
 * The ENABLE and CNT_THRESH fields of this register are preserved      *

 * If the UCE valid bit is set, the address field contains a pointer    *
 * to the Hspec address of the offending directory entry, the           *
 * syndrome field contains the bad syndrome, and the UCE overrun bit    *
 * indicates whether multiple double-bit errors were received.          *
 * If the UCE valid bit is clear but the AE valid bit is set, the       *
 * address field contains a pointer to the Hspec address of the         *
 * offending protection entry, the Bad Protection field contains the    *
 * 4-bit bad protection value, the PROT_INDEX field shows which of      *
 * the 8 protection values in the word was bad and the AE overrun bit   *
 * indicates whether multiple AE errors were received.                  *

 * Description:  Contains information on uncorrectable and              *
 * correctable directory ECC errors, along with protection ECC          *
 * errors. The priority of ECC errors latched is: uncorrectable         *
 * directory, protection error, correctable directory. Thus the valid   *
 * bits signal:                                                         *
 * 1xxx: uncorrectable directory ECC error (UCE)                        *
 * 01xx: access protection double bit error (AE)                        *
 * 001x: correctable directory ECC error (CE)                           *
 * 0001: access protection correctable error (ACE)                      *
 * If the UCE valid bit is set, the address field contains a pointer    *
 * to the Hspec address of the offending directory entry, the           *
 * syndrome field contains the bad syndrome, and the UCE overrun bit    *
 * indicates whether multiple double-bit errors were received.          *
 * If the UCE valid bit is clear but the AE valid bit is set, the       *
 * address field contains a pointer to the Hspec address of the         *
 * offending protection entry, the Bad Protection field contains the    *
 * 4-bit bad protection value, the PROT_INDEX field shows which of      *
 * the 8 protection values in the word was bad and the AE overrun bit   *
 * indicates whether multiple AE errors were received.                  *
 * If the UCE and AE valid bits are clear, but the CE valid bit is      *
 * set, the address field contains a pointer to the Hspec address of    *
 * the offending directory entry, the syndrome field contains the bad   *
 * syndrome, and the CE overrun bit indicates whether multiple          *
 * single-bit errors were received.                                     *
