Channel Rank Interleave Way Range Registers. These registers allow the user to define
the ranks and offsets that apply to the ranges defined by the LIMIT in the
MC_RIR_LIMIT_CH registers. The mappings are as follows:
RIR_LIMIT_CH{chan}[0] -> RIR_WAY_CH{chan}[3:0]
RIR_LIMIT_CH{chan}[1] -> RIR_WAY_CH{chan}[7:6]
RIR_LIMIT_CH{chan}[2] -> RIR_WAY_CH{chan}[11:10]
RIR_LIMIT_CH{chan}[3] -> RIR_WAY_CH{chan}[15:14]
RIR_LIMIT_CH{chan}[4] -> RIR_WAY_CH{chan}[19:18]
RIR_LIMIT_CH{chan}[5] -> RIR_WAY_CH{chan}[23:22]
RIR_LIMIT_CH{chan}[6] -> RIR_WAY_CH{chan}[27:26]
RIR_LIMIT_CH{chan}[7] -> RIR_WAY_CH{chan}[31:28]

Value
OFFSET.
RW 0
This field defines the offset used in the rank interleave. This is a 2's
complement value.
RANK.
This field defines which rank participates in WAY(n). If MC.CLOSEDPAGE=1, this
field defines the DRAM rank selected when MemoryAddress[7:6]=(n). If
RW 0
MC.CLOSEDPAGE=0, this field defines which rank is selected when
MemoryAddress[13:12]=(n). (n) is the instantiation of the register. This field is
organized by physical rank. Bits [3:2] are the encoded DIMM ID(slot). Bits
[1:0] are the rank within that DIMM.
