Currently pxb-pcie is not supported by arm, the reason for it is
pxb-pcie is not described in DSDT table and only one main host bridge
is described in acpi tables, which means it is not impossible to
present different io numas for different devices, especially
host-passthrough devices.

This series of patches make arm to support PXB-PCIE.

Users can configure pxb-pcie with certain numa, Example command
is:

   -device pxb-pcie,id=pci.7,bus_nr=128,numa_node=0,bus=pcie.0,addr=0x9

Since the bus of pxb-pcie is root bus, devices could not be plugged
into pxb-pcie directly,pcie-root-port or pci-bridge should be defined
and plugged on pxb-pcie, then the device could be plugged onto the
pcie-root-port or pci-bridge.

With the patches,io numa could be presented to the guest by define a
pxb-pcie with the numa and plug the device on it.

Hi,

This series failed the docker-quick@centos7 build test. Please find the testing commands and
their output below. If you have Docker installed, you can probably reproduce it
