IIRC the only thing this function does is touch ACPI and OF stuff?
Isn't that firmware?

AFAICT amba uses this because AMBA devices might be linked to DT
descriptions?

But DT descriptions aren't firmware.  They are usually either passed onb
the bootloader or in some deeply embedded setups embedded into the
kernel image.

Pedenatically yes, but do you know of a common word to refer to both
OF and ACPI that is better than firmware? :)

AFAICT we already use firwmare for this in a few places, eg
fwnode_handle and so on.

I've always thought 'platform' was the generic name for otherwise
non-enumerable platform-firmware/data things enumerated by ACPI / OF.
