* Note concerning support for "module-level code".
*
* ACPI 1.0 allowed Type1 and Type2 executable opcodes outside of control
* methods (the so-called module-level code.) This support was explicitly
* removed in ACPI 2.0, but this type of code continues to be created by
* BIOS vendors. In order to support the disassembly and recompilation of
* such code (and the porting of ASL code to iASL), iASL supports this
* code in violation of the current ACPI specification.
*
* 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.
* The ObjectList term is obsolete and has been removed.
