| * Define platform specific Memory Down Configure structure. |
| * |
| * If CONFIG(ENABLE_FSP_MEMORY_DOWN) is enabled, the MEMORY_DOWN_CONFIG |
| * structure should be customized to match the design. |
| * |
| * .SlotState indicates the memory down state of the specific channel/DIMM. |
| * |
| * SlotState options: |
| * |
| * STATE_MEMORY_DOWN: Memory down. |
| * STATE_MEMORY_SLOT: Physical memory slot. |
| * |
| * .SpdDataLen should always be MAX_SPD_BYTES/512. |
| * |
| * .SpdDataPtr is pointing to the SPD data structure when memory modules |
| * are memory down. |
| * |
| * 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}} |
