DESCRIPTION
The size and type of this Base Address Register are defined from Upstream
Memory 0 Setup Register (Offset E4h), which can be initialized by
EEPROM (I2C) or SM Bus or Local Processor. The range of this register is
from 4KB to 2GB. The lower 4KB if this address reange map to the
PI7C9X110 CSRs into memory space. The remaining space is this range
above 4KB, if any, specifies a range for forwarding upstream memory
transactions. PI7X9X110 uses upstream Memory 0 Translated Base Register
(Offset E0h) to formulate direct address translation. If a bit in the setup
register is set to one, then the correspondent bit of this register will be
changed to RW.

The size and type of this Base Address Register are defined from Upstream
IO or Memory 1 Setup Register (Offset ECh), which can be initialized by
EEPROM (I2C) or SM Bus or Local Processor. Writing a zero to bit [31] of
the setup register to disable this register. The range of this register is from
4KB to 2GB for memory space or from 64B to 256B for IO space.
PI7X9X110 uses upstream IO or Memory 1 Translated Base Register (Offset
E8h) to formulate direct address translation. If a bit in the setup register is
set to one, then the correspondent bit of this register will be changed to RW.
