I'm asking why we don't fix the actual problem in PCIe ARM64 adaptation instead of working around it by quirks. I don't see any reason why ACPI ARM64 should carry the burden of legacy systems. Legacy only applies to DT based systems.I fully agree with this point: ACPI implies firmware, and so we should be able to rely on firmware to have initialized the PCIe subsystem by the time the kernel gets to access it.
