Well, lack of PCI support on ARM64 is a much better reason for accepting
the patch than potential use on non-server platforms of course.
What is the status of the PCI work though? I suspect it won't be all
that hard to add minimal PCI support for a simple mmconfig plus
fixed I/O space based host of the kind that qemu can easily provide.
The hard part that we want to share code with other architectures is
supporting pluggable host controllers, and I think we can defer that
a bit.
