 * The reference design we are copying calls for a couple of RF chip

 * suitable as either the input or the output, but the package shape is
 * asymmetrical, thus it is a PCB layout decision which pin will be the
 * input and which will be the output.
 *
 * We shall use a mapped_pins primitive and two different pinout mappings
 * at the MCL binding stage, to be selected at layout time.
