This was just an example? Or why is the base address of the IO space 0xf1000000? What in the OFW-tree tells me to use this address? I would have used the address of the IO space from the PCI node which contains the /isa tree, which is 0xfe000000. Maybe Tim has understood, but I don't... ;) -- Frank Wille
