dev/pci/pci_host_generic_acpi.c — generic ECAM PCIe driver.

I think ThunderX2 uses it (2018 Cavium copyright in the file), probably 
Ampere eMAG (haven't seen anything about that here, but the vendor 
lists FreeBSD in their OS compatibility list), should be possible to 
use on the SoftIron Overdrives (NetBSD just added ACPI/aarch64 and they 
tested on the Overdrive: 
https://dmesgd.nycbug.org/index.cgi?do=view&id=4526 — but all 
FreeBSD+SoftIron dmesgs on dmesgd.nycbug so far are in FDT mode, not 
ACPI)…

And the EDK2 firmware for the Armada8k does have an ACPI mode…
