Something isn't working
Need to investigate and see what workarounds are available in each OS.
At quick glance, Linux does have custom ECAM accessors for Synquacer and Armada. Can this bind to ACPI somehow?
Windows overall support is still a big question mark due to other unknown issues, but it is actually possible to expose both the root port and full config space via separate MCFG entries on the same segment, with "NXPMX6" set as OEMID for FADT. The only drawback seems to be that this forces BAR space allocations to happen in the 32-bit MMIO window, which is much smaller.
