This register provides SAD DRAM package assignments. When the corresponding
DRAM_RULE hits, a 3-bit number (determined by mode) is used to index into the
interleave_list to determine which package is the HOME for this address.

LIMIT
DRAM rule top limit address. Must be strictly greater than previous rule, even if
RW -
this rule is disabled, unless this rule and all following rules are disabled. Lower
limit is the previous rule (or 0 if it is first rule). This field is compared against
MA[39:26] in the memory address map.
MODE
DRAM rule interleave mode. If a DRAM_RULE hits a 3 bit number is used to
index into the corresponding interleave_list to determine which package the
DRAM belongs to. This mode selects how that number is computed.
RW -
00 = Address bits {8,7,6}.
01 = Address bits {8,7,6} XORed with {18,17,16}.
10 = Address bit {6}, MOD3(Address[39..6]). (Note 6 is the high order bit)
11 = Reserved.
ENABLE
Enable for DRAM rule. If Enabled Range between this rule and previous rule is
RW 0
Directed to HOME channel (unless overridden by other dedicated address range
registers). If disabled, all accesses in this range are directed in MMIO to the
IOH.
