64  * Note concerning support for "module-level code".
65  *
66  * ACPI 1.0 allowed Type1 and Type2 executable opcodes outside of control
67  * methods (the so-called module-level code.) This support was explicitly
68  * removed in ACPI 2.0, but this type of code continues to be created by
69  * BIOS vendors. In order to support the disassembly and recompilation of
70  * such code (and the porting of ASL code to iASL), iASL supports this
71  * code in violation of the current ACPI specification.
72  *
73  * The grammar change to support module-level code is to revert the
74  * {ObjectList} portion of the DefinitionBlockTerm in ACPI 2.0 to the
75  * original use of {TermList} instead (see below.) This allows the use
76  * of Type1 and Type2 opcodes at module level.
77  *
78  * 04/2016: The module-level code is now allowed in the following terms:
79  * DeviceTerm, PowerResTerm, ProcessorTerm, ScopeTerm, ThermalZoneTerm.
80  * The ObjectList term is obsolete and has been removed.
