All I know is that I experienced the same phantom device problem you are seeing.

All I know is that with the 8349 and 8360 processor cards, I could configure PCI in U-Boot and I could get to a U-Boot prompt even if the processor card was not attached to the PIBs. I could also boot a Linux kernel w/ PCI support with or without the PIBs. With the 832x card, if I configured PCI in U-Boot, the card would hang if it was not connected to the PIBs. > > Could the Lowboot affect the PCI bus?
