Ben,
I tried:
/* Workaround for lack of device tree */
if (primary) {
__ioremap_at(range.cpu_addr, (void
*)ISA_IO_BASE,
range.size, pgprot_noncached(PAGE_KERNEL));
hose->io_base_virt = (void *)_IO_BASE;
printk("Initialised io_base_virt 0x%lx _IO_BASE
0x%llx\n", (unsigned long)hose->io_base_virt, (unsigned long long)_IO_BASE);
}
Unfortunately I got some error messages:
arch/powerpc/kernel/pci-common.c: In function
‘pci_process_bridge_OF_ranges’:
arch/powerpc/kernel/pci-common.c:731:32: error: incompatible type for
argument 4 of ‘__ioremap_at’
__ioremap_at(range.cpu_addr, (void

Actually, can you try pgprot_noncached(PAGE_KERNEL) ? If that works,
then I wonder what that's going on in pci_64.c ...
Cheers,
Ben.
