[PATCH 00/17] Implement ACPI on aarch64

That sounds reasonable. I'll look into that as well.

The ACPI code is identical to the tianocore one. However the U-Boot
implementation
is a bare minimum to boot a Linux OS, thus yes there are differences
between those
firmwares. EDK2 has more quirks for various boards and reads in UEFI
variables to
enable/disable certain devices or features.
