*
* The grammar change to support module-level code is to revert the
* {ObjectList} portion of the DefinitionBlockTerm in ACPI 2.0 to the
* original use of {TermList} instead (see below.) This allows the use
* of Type1 and Type2 opcodes at module level.
*
* 04/2016: The module-level code is now allowed in the following terms:
* DeviceTerm, PowerResTerm, ProcessorTerm, ScopeTerm, ThermalZoneTerm.
