What in the OFW-tree tells me to use this address? 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). -- tschüß, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
