+ * Define platform specific Memory Down Configure structure.

+ * .SlotState indicates the memory down state of the specific channel/DIMM.

+ * .SpdDataLen should always be MAX_SPD_BYTES/512.

+ * SpdDataPtr options:
+ *
+ *     Non-NULL: Pointing to SPD data structure.
+ *     NULL: Physical memory slot, no SPD data used.

+ * DIMM Mapping of SlotState & SpdDataPtr:
+ *
+ *     {{CH0DIMM0, CH0DIMM1}, {CH1DIMM0, CH1DIMM1}}
