+/*!
+ * Naming convention for AML interpreter execution routines.
+ *
+ * The routines that begin execution of AML opcodes are named with a common
+ * convention based upon the number of arguments, the number of target operands,
+ * and whether or not a value is returned:
+ *
+ *      AcpiExOpcode_xA_yT_zR
+ *
+ * Where:
+ *
+ * xA - ARGUMENTS:    The number of arguments (input operands) that are
+ *                    required for this opcode type (1 through 6 args).
+ * yT - TARGETS:      The number of targets (output operands) that are required
+ *                    for this opcode type (0, 1, or 2 targets).
+ * zR - RETURN VALUE: Indicates whether this opcode type returns a value
+ *                    as the function return (0 or 1).
+ *
+ * The AcpiExOpcode* functions are called via the Dispatcher component with
+ * fully resolved operands.
