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…home | help
