Controls the memory interleaving size. This determines the starting address of
the interleave (bit 8, 9, 10 or 11).
Options available: Auto, 256Bytes, 512Bytes, 1KB, 2KB. Default setting is Auto.
Enable/Disable to remap DRAM out of the space just below the 1TB boundary.
The ability to remap depends on DRAM configuration, NPS, and interleaving
selection, and may not always be possible.
Options available: Auto, Do not remap, Attempt to remap.
Default setting is Auto.
Enable/Disable the DRAM map inversion function.
Options available: Auto, Enabled, Disabled. Default setting is Auto.
Control whether or not the rpivate memory regions (PSP, SMU, and CC6) are
at the top of DRAM or distributed. Note that distributed requires memory on
all dies. Note that it will always be at the top of DRAM if some dies don't have
memory regardless of this.
Options available: Auto, Distributed, Consolidated. Default setting is Auto.
