Upper Programmable Base Address: These bits are
part of the SM MMR region, normally set by configuration
software to locate the base address of the region. The
actual behavior of this field depends on the SM MMR
Enable bit in the IMCH TST2 register (bit 6) as defined
above. When IMCH TST2[6] = 1 these bits are Read/Write.
When IMCH TST2[6] = 0 these bits are Read-Only as
zeros.
Lower Bits: These bits are hardwired to 0. This forces the
size of the memory region to be 4 Kbyte.
Prefetchable: This bit is hardwired to 0 to indicate that
the System Memory MMR region is NON-Prefetchable.
Addressing Type: These bits determine addressing type
and they are hardwired to 00 to indicate that address
range defined by the upper bits of this register can be
located anywhere in the 32-bit address space in order to
comply with the PCI specification for base address
registers.
Memory Space Indicator: Hardwired to 0 to identify the
MMR range as a memory range as per the specification for
PCI base address registers.
