132 * Naming convention for AML interpreter execution routines.

135 * convention based upon the number of arguments, the number of target operands,
136 * and whether or not a value is returned:
137 *
138 * AcpiExOpcode_xA_yT_zR
139 *
140 * Where:
141 *
142 * xA - ARGUMENTS: The number of arguments (input operands) that are
143 * required for this opcode type (1 through 6 args).
144 * yT - TARGETS: The number of targets (output operands) that are required
145 * for this opcode type (0, 1, or 2 targets).
146 * zR - RETURN VALUE: Indicates whether this opcode type returns a value
147 * as the function return (0 or 1).
148 *
149 * The AcpiExOpcode* functions are called via the Dispatcher component with
150 * fully resolved operands.
