I'm not trying to base everything on ACPI, this happens in the first
patces though. I would separate them in the future release.
(Actually I put comments about it in the first patch:)

There will be the dependent and independent codes. Any platform
can share the independent code, and dependent code needs to
be made by each platform. I think that PCI hotplug takes the same
way.

Thanks,
