The ranges property of the PCI and ISA bus nodes will tell you the
address mapping. Have a look into ofppc/pci/ofpci.c, especially
init_spaces(), from my hacked up ofppc code. It reads and decodes the
ranges property of the PCI and ISA bus nodes and does quite some
gueswork to initialize bus_space(9).
