      [PATCH] powerpc: add refcounting to setup_peg2 and of_get_pci_address · d60dcd94
      Olaf Hering authored
      setup_peg2 must do some refcounting.
      of_get_pci_address may need to drop the node

      [PATCH] powerpc: Recognize /chaos bridge on old pmacs as PCI · d5f07900
      Paul Mackerras authored
      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.
