+ <description>
+ Bad DQ bitmap from a Centaur:MBA point of view.
+ The data is a 10 byte bitmap for each of 4 possible ranks.
+ The bad DQ data is stored in DIMM SPD, it is stored in a special format
+ and is translated to a DIMM Connector point of view for IS-DIMMs.
+ All of these details are hidden from the user of this attribute.

+ <description>
+ Spare DRAM availability for each rank on the DIMM.
+ There are 8 DQ lines to spare DRAMs.
+ - NO_SPARE: No spare DRAMs
+ - LOW_NIBBLE: x4 DRAMs in use, one spare DRAM connected to SP_DQ0-3
+ - HIGH_NIBBLE: x4 DRAMs in use, one spare DRAM connected to SP_DQ4-7
+ - FULL_BYTE: Either
+ 1/ x4 DRAMs in use, two spare DRAMs connected to SP_DQ0-7
+ 2/ x8 DRAMs in use, one spare DRAM connected to SP_DQ0-7
+ For C-DIMMs, this is in a VPD field : Record:VSPD, Keyword:AM
+ For IS-DIMMs, the platform should return 0 indicating
+ no spares for any rank.
+ The top 2 bits are for rank 0 e.g:
+ if (((val AND 0xc0) >> 6) ==
+ ENUM_ATTR_VPD_DIMM_SPARE_LOW_NIBBLE) {...}
+ The next 2 bits are for rank 1 e.g:
+ if (((val AND 0x30) >> 4) ==
+ ENUM_ATTR_VPD_DIMM_SPARE_NO_SPARE) {...}
+ The next 2 bits are for rank 2 e.g:
+ if (((val AND 0x0c) >> 2) ==
+ ENUM_ATTR_VPD_DIMM_SPARE_HIGH_NIBBLE) {...}
+ The bottom 2 bits are for rank 3 e.g:
+ if ((val AND 0x03) ==
+ ENUM_ATTR_VPD_DIMM_SPARE_FULL_BYTE) {...}
