MC_CHANNEL_MAPPER
Channel mapping register. The sequence of operations to update this register is:
Read MC_Channel_Mapper register
Compare data read to data to be written. If different then write.

MC_MAX_DOD
This register defines the MAX number of DIMMS, RANKS, BANKS, ROWS, COLS among
all DIMMS populating the two channels. The Memory Init logic uses this register to
cycle through all the memory addresses writing all 0s to initialize all locations.
