 * 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.
