Well, I proposed an alternative (better) approach which I of course had
no time to actually implement yet :-)

I have done the changes I needed to do to powerpc
pci_process_bridge_OF_ranges so it would be possible to move that now to
a generic place, but I still think it's not a great idea. It means the
pci_controller structure with its resources will have to become generic
which somewhat overlaps with the pci_host_bridge that Bjorn introduced,
so that's really not great.

I still think an arch with DT and simpler PCI code that powerpc could
start looking at the transition to a better model that I hinted at...

Cheers,
Ben.
