Here's another try. The biggest change is to add the APM X-Gene quirks.
These are on my pci/ecam branch. Please test and report any issues.
Please also collect dmesg and /proc/iomem contents and I'll try to
summarize the current ACPI firmware situation on ARM64 and update the
writeup with recommendations for future platforms.
Changes from v10 to v11:
- Discard "consumer" resources from PNP0A03 host bridge windows (arm64
only). This allows using consumer PNP0A03 descriptors (rather than the
PNP0C02 workaround used on x86) for bridge register space.
- Add APM X-Gene MCFG quirks.
- If ACPI and quirks are enabled, always build ThunderX, X-Gene, and
HiSilicon drivers on ARM64. Add internal ifdefs so we only compile the
parts necessary for ACPI (the ECAM init and accessors).
- s/node/seg/ in ThunderX MCFG quirk macros.
- Move ECAM check for ACPI device reservation from pci_ecam_create() to
that arm64-specific pci_acpi_setup_ecam_mapping().
- Add local "struct device *dev" pointers for brevity.
- Miscellaneous build fixes.
