MMCONFIG will not work with acpi=off any more.
I don't think this is unreasonable. The ACPI MCFG table is how we are
supposed to learn about the area in the first place. If we can't get the
table location via an approved mechanism, and can't validate it doesn't
overlap with another memory reservation or something, I really don't
think we should be using it.
I don't think it's much of an issue anyway - the chances that somebody
will want to run without ACPI on a system with MCFG are pretty low given
that you'll end up losing a bunch of functionality (not least of which
is multi-cores).
because acpi_init==>pci_mmcfg_late_init==>pci_mmcfg_check_hostbridge...
can you move pci_mmcfg_later_init out of acpi_init and just call
somewhere after acpi_init...
or put pci_mmcfg_check_hostbridge back to pci_mmcfg_early_init?
