Have you set any specific flags ? IE. Modified the value of
ppc_pci_flags from what the 4xx code sets originally ?

It does look to me like some of your device BARs have been setup already
by the firmware in a way that conflict with the way you configure your
ranges, and the kernel doesn't appear to detect nor try to remap that
which would happen if you have the "probe only" flag set.

IE. On your c0000000 bus, you have memory at 90000000 CPU space mapped
to 80000000 PCI space. However, when probing, the kernel finds:

pci 0001:41:00.0: reg 10 32bit mmio: [0x90000000-0x9001ffff]

IE. A BAR was already set with a value of 90000000 PCI-side which is out
of the bounds you have for your bus.

Maybe you really want to configure that second bus to have CPU 90000000
mapped to 90000000 PCI-side ? (IE. a 1:1 mapping). That would be
something to fix in your "ranges" property.

Ben.
