* Define platform specific Memory Down Configure structure.

*
* SlotState options:

* STATE_MEMORY_DOWN: Memory down.
* STATE_MEMORY_SLOT: Physical memory slot.
*
* .SpdDataLen should always be MAX_SPD_BYTES/512.

* Non-NULL: Pointing to SPD data structure.

*
* DIMM Mapping of SlotState & SpdDataPtr:
