Subject[PATCH 0/8] PCI, ACPI, x86: Reserve fw allocated resource for hot-add root bus
For root bus hot add, fw could assign some resource for the devices for
that root bus before notifying os via acpi, we should check and use those
resources at first just like we do for booting path.

At first, we need to refactor x86 pci pcibios_allocate related functions
for booting path to take bus as parameter.

After that, we could use the survey function for hot add root bus.

based on pci/yinghai-for-pci-root-bus-hotplug

could get from
git:// for-pci-survey-resources

Yinghai Lu (8):
PCI, x86: Separate out pcibios_allocate_bridge_resources()
PCI, x86: Separate out pcibios_allocate_dev_resources()
PCI, x86: Let pcibios_allocate_bus_resources() take bus instead
PCI, x86: Separate out rom resource claim
PCI, x86: Add pcibios_fw_addr_done
PCI, x86: Remove __init for hw/fw allocated functions
PCI, x86: Claim FW allocated resources in hot add path.
PCI, ACPI: reserve fw allocated resource for hot added root bus
