So it would seem to me that we need some kind of a scheme for allocating I/O port base addresses if OF didn't do it. I'm vaguely familiar with the concepts behind PCI address space allocation, having looked at it from the hardware design POV a while back, but I'm not familiar enough with the kernel code yet to tackle this problem (or to even be sure that I'm on the right track here).That should be handled by the new, 2.3 PCI code with dynamic resurce allocation. I've just discovered that part, however, and am not at all familiar with it. I'm RTFS'ing...
Another piece of code to look at might be the Alpha arch PCI code in 2.2. From what I can tell it is doing complete configuration of PCI by itself (apparently the firmware on Alpha boards doesn't do any PCI config). Tim Seufert ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
