ditto, refer to to the first revision where it's appeared

index and len could be only of 'Integer' type, so there is no point
to pass them in as Aml, just use uintFOO_t here and convert
them to aml_int() internally. That way call sites will be smaller
and have less chance to pass a wrong Aml variable.
