Hi,
I'm wondering whenever things become easier if we add config registers to the pxb, where the firmware can program the bus number range and we can use the config register base as a way to specify which pxb we are referring to ?
... and, while thinking about ben's reply elsewhere in this thread, maybe even decouple the whole thing from the primary root bus? You can't program the devices via 0x0cf8 then, but we could add a mmconfig bar to the host bridge device ...
cheers, Gerd
