[PATCH v6 0/8] pci_expander_brdige:acpi:Support pxb-pcie for ARM

[Yubo Miao <miaoyubo@huawei.com>]

From: miaoyubo <miaoyubo@huawei.com>

Changes with v5
v5->v6: stat crs_range_insert in aml_build.h

Changes with v4
v4->v5: Not using specific resources for PXB.
Instead, the resources for pxb are composed of the bar space of the
pci-bridge/pcie-root-port behined it and the config space of devices
behind it.

Only if the bios(uefi for arm) support multiple roots,
configure space of devices behind pxbs could be obtained.
The uefi work is updated for discussion by the following link:

[PATCH] ArmVirtPkg/FdtPciHostBridgeLib: add extra roots for Arm.

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.

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

miaoyubo (8):
  acpi: Extract two APIs from acpi_dsdt_add_pci
  fw_cfg: Write the extra roots into the fw_cfg
  acpi: Extract crs build form acpi_build.c
  acpi: Refactor the source of host bridge and build tables for pxb
  acpi: Align the size to 128k
  unit-test: The files changed.
  unit-test: Add testcase for pxb
  unit-test: Add the binary file and clear diff.h
