+ *               \------------------------------ Resync (always set)
+ *
+ * The client writes it's request into MC shared memory, and rings the
+ * doorbell. Each request is completed by either by the MC writting
+ * back into shared memory, or by writting out an event.
+ *
+ * All MCDI commands support completion by shared memory response. Each
+ * request may also contain additional data (accounted for by HEADER.LEN),
+ * and some response's may also contain additional data (again, accounted
+ * for by HEADER.LEN).
+ *
+ * Some MCDI commands support completion by event, in which any associated
+ * response data is included in the event.
+ *
+ * The protocol requires one response to be delivered for every request, a
+ * request should not be sent unless the response for the previous request
+ * has been received (either by polling shared memory, or by receiving
+ * an event).

+ *

+ *
+ *   These fields are taken directly out of the standard MCDI header, i.e.,
+ *   LEVEL==ERR, Datalen == 0 => Reboot

+ *      0         7        8
+ *     | command | Resync |     = 0xc0
