RE: [PATCH] powerpc/pci: check the bus address instead of resource address in pcibios_fixup_resources

If a BAR has the value of 0, we would assume that it is unset yet and then mark the resource as unset and would reassign it later.
IIRC the PCI spec allows a BAR address of zero. Certainly some sparc systems have assigned 0 to a BAR. So assuming a BAR of 0 means it is unset may not be true for all systems. David
