PCI: remove unused arch pcibios_update_resource() functions
Russell King did the following back in 2003: <-- snip --> [PCI] pci-9: Kill per-architecture pcibios_update_resource() Kill pcibios_update_resource(), replacing it with pci_update_resource(). pci_update_resource() uses pcibios_resource_to_bus() to convert a resource to a device BAR - the transformation should be exactly the same as the transformation used for the PCI bridges. pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to set the high 32-bits to anything non-zero - currently no architecture attempts to do something different. If anyone cares, please fix; I'm going to reflect current behaviour for the time being. Ivan pointed out the following architectures need to examine their pcibios_update_resource() implementation - they should make sure that this new implementation does the right thing. #warning's have been added where appropriate. ia64 mips mips64 This cset also includes a fix for the problem reported by AKPM where 64-bit arch compilers complain about the resource mask being placed in a u32. <-- snip --> This patch removes the unused pcibios_update_resource() functions the kernel gained since, from FRV, m68k, mips & sh architectures.
