[Qemu-devel] [RFC 8/9] pcihp: expose PCI hotplug MMIO base/length as properties of piix4pm

2014-02-07 Thread Igor Mammedov
with introduction of PCIHP, MMIO range becomes changable at runtime so it's not possible to statically punch hole PCI bus _CRS. Making IO base/length available as readonly properties allow acpi builder to get values and reserve PCI hotplug IO range at runtime later. Signed-off-by: Igor Mammedov
