MC_MAX_DOD
This register defines the MAX number of DIMMS, RANKS, BANKS, ROWS, COLS among
all DIMMS populating the three channels. The Memory Init logic uses this register to
cycle through all the memory addresses writing all 0's to initialize all locations. This
register is also used for scrubbing and sparing and must always be programmed if any
DODs are programmed.
