IIRC those SoCs did not use standard EFI/ACPI though, but rather some
other special firmware, I think it was SFI ? This is not so much about
the CPU architecture as it is about the firmware/bootloader <->
OS interface.

Note I'm not saying this can not be done with EFI/ACPI systems, but
I think it has never been tried.
