DESCRIPTION
The size of this Base Address Register is defined from Downstream Memory
3 Upper 32-bit Setup Register (CSR Offset 018h), which can be initialized by
EEPROM (I2C) or SM Bus or Local Processor. Writing a zero to bit [31] of
the setup registers (CSR Offset 018h) to disable this register. This register
defines the upper 32 bits of a memory range for downstream forwarding
memory. If a bit in the setup register is set to one, then the correspondent bit
of this register will be changed to RW.
