The two patches respectively: - provides the common function acpi_get_rc_resources() for ARM64 platform. - adds the HiSilicon ACPI specific quirks. This patchset is based on branch pci/ecam-v6 It can be found here: https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git(pci/ecam-v6) This patchset has been tested on HiSilicon D03 board. The dmesg log, /proc/iomem, and ACPI table information can be found: https://bugzilla.kernel.org/show_bug.cgi?id=187961 v5 -> v6: - change the config option to CONFIG_PCI_ECAM_QUIRKS. - fix some commets about acpi_get_rc_resources(). v4 -> v5: - obtain rc base addresses from PNP0C02 at the root of the ACPI namespace (under \_SB) instead of from sub-device under the RC. - merge the rewrited get rc resources code by Tomasz. - delete unused code. - drop the PATCH V4 1/2, will rework late as a separate patch. v3 -> v4: - rebase on pci/ecam-v6. - delete the unnecessary link_up check code. v2 -> v3: - rebase against 4.9-rc1 and add Tomasz quirks V6 pathcset. - obtain rc base addresses from PNP0C02 as subdevice of PNP0A03 instead of hardcode the addresses. - modify hisi_pcie_acpi_rd_conf/hisi_pcie_acpi_wr_conf() according to Arnd comments. v1 -> v2: - rebase against Tomasz RFC V5 quirk mechanism - add ACPI support for the HiSilicon Hip07 SoC PCIe controllers.
