      [PCI] pci-8: pci_resource_to_bus() · 2ef9c88b
      Russell King authored
      Convert pcibios_fixup_pbus_ranges() into something more generic, namely
      pcibios_resource_to_bus() - we are really trying to convert resources
      to something to program into bus registers for bridge windows, and in
      fact, PCI device BARs.
      
      This is necessary since some architectures, namely Alpha, ARM and PARISC
      have an offset between PCI addressing and host-based addressing, so
      resources need to be adjusted when read or when written back to the bus.
      
      We provide a generic version in asm-generic/pci.h, which most
      architectures use.
      
      This patch finds the following architectures with something to think
      consider:
      
              - ppc, ppc64
                      adjusts resources for devices, but not buses.
      		This is inconsistent, and leads to improperly
      		programmed windows/BARs.
      
      PPC people (Anton) has a replacement PCI resource implementation
      which should do the right thing.

      [PCI] pci-7: Remove second argument to pcibios_update_resource() · 032d6c6e
      Russell King authored
      Patch from Ivan Kokshaysky
      
      remove the "parent" or "root" second argument to
      pcibios_update_resource().  This highlights the following
      architectures doing something wrong in their implementation:
      
              - ia64
              - mips it8172
              - mips "generic mips boards"
              - mips64 "generic mips boards"
              - mips64 IP27

      [PCI] pci-6 - Fix scanning of non-zero functions · a9d96a6e
      Russell King authored
      Fix breakage in pci-3 - we scanned all functions if function 0 was not
      present.  This causes some host bridges to lock up when scanning devfn
      255 on PPC machines.
