PCI legacy I/O is not direct mapped: there is no legacy I/O on a
PowerPC system bus.  So, it can not be mentioned in the "ranges"
property, but the PHB registers used to access it should be shown
in the "reg" property.  It could be a simple linear window (it
sounds like it is here?), but it could for example also be implemented
via an address/data register pair.

Yes, it is a simple linear address window. I'll remove its address 
range from the reg property.

No, please remove it from the "ranges" property, instead.

What about the PCI2ISA bridge? I map the first 64k PCI I/O address space
as ISA I/O space by using a ranges property. Would that be incorrect,
too?
