The whole business with re-assigning all bus numbers, creating an OF bus "map" etc... is ancient powermac stuff that you really don't care about on microblaze. Similarly pci_device_from_OF_node() is unused and by getting rid of it we can get rid of a whole lot of code otherwise unused on this architecture Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Michal Simek <monstr@monstr.eu>
