[RFC 0/2] pci_expander_brdige:acpi:Support pxb-pcie for ARM

[Yubo Miao <miaoyubo@huawei.com>]

From: miaoyubo <miaoyubo@huawei.com>

Currently pxb-pcie is not supported by arm 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. 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 devices could not be plugged into pxb-pcie directly, one
pcie-root-port is auto plugged into the pxb, therefore, the devices
could be plugged into pxb-pcie.

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