<description>
Centaur DQ to DIMM connector DQ mapping.
Uint8 value for each Centaur DQ (0-79).
The value is the corresponding DIMM Connector DQ.
Therefore if (data[2] == 60) then Centaur DQ 2 maps to DIMM DQ 60
If the logical DIMM is on a Centaur-DIMM then the value is the same as the
array index because there is no DIMM connector.
If the logical DIMM is an IS-DIMM then the value depends on board wiring.

<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 all DIMMs connected to the target MBA.
For each rank on a 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
