The definitions of pci_xxx_config_yyy and pcibios_xxx_config_yyy are hard to
find.

pci_xxx_config_yyy are defined by the PCI_OP() macro in drivers/pci/pci.c
pcibios_xxx_config_yyy are defined by the PCI_OP() macro in
drivers/pci/compat.c

Thanks, Mark.

Here is what I found:

pci_read_config_byte =  generic_pcibios_read_byte =
ppc_md.pcibios_read_config_byte = indirect_pcibios_read_config_byte
in arch/ppc/kernel/indirect_pci.c

Yes, that is true because of the "set_config_access_method(indirect)" call in the
*_setup.c or *_pci.c routine for your platform (if you're looking at the
sandpoint, its in sandpoint_setup.c).  Other access methods are supported too.
