#     powerpc/pci: Add option for using pci_to_OF_bus_map
#     
#     The "pci-OF-bus-map" property was declared deprecated in 2006 [1] and to
#     the best of everyone's knowledge is not used by anything anymore [2].
#     
#     The creation of the property was disabled on powermac (arch/powerpc) in
#     2005 by commit 35499c0195e4 ("powerpc: Merge in 64-bit powermac
#     support."). But it is still created by default on CHRP.
#     
#     On powermac the actual map (pci_to_OF_bus_map) is still used by default,
#     even though the device tree property is not created.
#     
#     Add an option to enable/disable use of the pci_to_OF_bus_map, and
#     creation of the property (on CHRP).
#     
#     Disabling the option allows enabling CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT
#     which allows "normal" bus numbering and more than 256 buses, like 64-bit
#     and other architectures.
#     
#     Mark the new option as default n, the intention is that the option and
#     the code will be removed in a future release.
