Linux for arm64 v4.10 and later will complain if the ECAM config space is not reserved in the ACPI namespace:
acpi PNP0A08:00: [Firmware Bug]: ECAM area [mem 0x3f000000-0x3fffffff] not reserved in ACPI namespace
The rationale is that OSes that don't consume the MCFG table should still be able to infer that the PCI config space MMIO region is occupied.
So update the ACPI tables to add this reservation.

Ping?
Looks entirely plausible to me, but I'd prefer to see a review from one of the ACPI people on cc as well.
Graeme?
Another one where I did not actually get the original email!
Wow, your spam folder must be the place to be ;)
Looks sane to me and what was expected from PCI maintainer.
