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.
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.
