    PCI: Call pci_read_bridge_bases() from core instead of arch code · dff22d20
    Lorenzo Pieralisi authored
    When we scan a PCI bus, we read PCI-PCI bridge window registers with
    pci_read_bridge_bases() so we can validate the resource hierarchy.  Most
    architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but
    PCI-PCI bridges are not arch-specific, so this doesn't need to be in
    arch-specific code.
    
    Call pci_read_bridge_bases() directly from the PCI core instead of from
    arch code.
    
    For alpha and mips, we now call pci_read_bridge_bases() always; previously
    we only called it if PCI_PROBE_ONLY was set.
