[Qemu-devel] [PATCH v2 0/4] pc: make ACPI pcihp more reusable

[Igor Mammedov <imammedo@redhat.com>]

changes since v1:
 - add BSEL property to root bus when in compatibility mode
     as result dropped "hw:acpi:pcihp: assume root PCI bus if bus has no ACPI_PCIHP_PROP_BSEL property"
 - rebasing on top of "pcihp: reduce number of device check events"
   added patch 3/4.

Reuses new pcihp code for handling legacy PCI hotplug in
acpi/piix4_pm, which significantly reduces code duplication
between piix4_pm and pcihp amd makes pcihp less dependend
on piix4 specific details.

It also allows cleaner rebase of generic hotplug refactoring,
by not increasing code duplication since it will need to be
done only for pcihp.

Git tree for testing based on mst's PCI tree:
