ation for the later "[PATCH 1/8] kvm tools: Add
initial SPAPR PPC64 architecture support" patch, which uses it. I could've
mushed that into the later PPC series but I thought it'd be clearer to do the
generic/x86 stuff separately.

or is
there any value to the expanded the return codes (and updating api.txt) for
varying kinds of positive success?

I forgot to mentio
PPC KVM doesn't yet support ioeventfds, so don't bomb out/die. virtio-pci is
able to function if it instead uses normal IO port notification.

This is the final piece of the puzzle for PPC SPAPR PCI; this
function splits MMIO accesses into the two PHB windows & directs
things to MMIO/IO emulation as appropriate.

This provides the PCI bridge, definitions for the address layout of the windows
and wires in IRQs. Once PCI devices are all registered, they are enumerated and
DT nodes generated for each.

requires virtio to gracefully fall back when it fails to register one.

vesa, pci-shmem and virtio-pci devices need to set up config space with
little-endian conversions (as config space is LE). The pci_config_address
bitfield also needs to be reversed when building on BE systems.
