GTDT is part of ACPI spec, drivers/acpi/ is for driver code of
ACPI spec, I think it can stay in drivers/acpi/ from this point
of view, am I right?

The question is not "Can it?", but "Does it need to?".

It is in the spec, but still there's only one architecture needing it.

There is no way to test it on any other architecture and no reason to build it
for any other architecture, so why does it need to be located in drivers/acpi/ ?

I'm fine to move it to other places such as arch/arm64/kernel/, but I
would like to ask ARM64 maintainer's suggestion for this.

Will, Catalin, what's your opinion on this?

We don't have any device-tree code for the architected timer under
arch/arm64, so I don't see why we should need anything for ACPI either.
