[PATCH] powerpc: Recognize /chaos bridge on old pmacs as PCI
The first generation of PCI powermacs had a host bridge called /chaos which was for all intents and purposes a PCI host bridge, but has a device_type of "vci" in the device tree (presumably it's not really PCI at the hardware level or something). The OF parsing stuff in arch/powerpc/kernel/prom_parse.c currently doesn't recognize it as a PCI bridge, which means that controlfb.c can't get its device addresses. This makes prom_parse.c recognize a device_type of "vci" as indicating a PCI host bridge. With this, controlfb works again.
