The size and type of this Base Address Register are defined from Downstream
Memory 0 Setup Register (Offset 9Ch), 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 PI7C9X130 CSRs
into memory space. The remaining space is this range above 4KB, if any,
specifies a range for forwarding downstream memory transactions.
PI7X9X110A uses downstream Memory 0 Translated Base Register (Offset
98h) 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.
