[POWERPC] Assign all PCI busses on G3 Blue & White
G3 Blue & White is misconfigured by default so that CardBus controllers in PCI slots don't work. The PCI bridge is programmed to only allow access to bus 1 but not higher busses. The patch forces the PCI busses to be reassigned if a Grackle controller is found and the machine identifies itself as "PowerMac1,1" Signed-off-by: Pavel Roskin <proski@gnu.org> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
