BASE_ADDRESS: Set by the OS, these bits correspond to address signals (31:22).
The ISP will compare the IOSF address (31:22) with ISPMMADR(31:22). If there is a
match, and PCICMDSTS(1) = MSE = 1 and the IOSF command is either a MEMRD or
MEMWR, the ISP will select the command and present it on the AHB bus to the vendor
IP.
