We'll have a better idea once we see more arm64 hardware. In the
meantime, what I know for sure is that we need a PCIe implementation
that is able to share drivers/host/* code between arm and arm64 (and
possibly other architectures). We had some attempts for more unification
between arm64, powerpc, microblaze, mips
work is ongoing.

If size becomes an issue, the next step for multi-platform could be
compiling as much SoC-related code as possible into loadable modules
that can go into initramfs.
