This field specifies the top of the range being mapped to the ranks specified in
This field specifies the top of the range being mapped to the ranks specified in
the MC_RIR_WAY_CH registers. The most significant bits of the lowest address
in this range is one greater than the limit field in the RIR register with the next
lower index. This field is compared against MA[37:28].
