     14 * enum - Predefined Mailbox Messages
     15 *
     16 * @RP_MBOX_READY: informs the M3's that we're up and running. this is
     17 * part of the init sequence sent that the M3 expects to see immediately
     18 * after it is booted.
     19 *
     20 * @RP_MBOX_PENDING_MSG: informs the receiver that there is an inbound
     21 * message waiting in its own receive-side vring. please note that currently
     22 * this message is optional: alternatively, one can explicitly send the index
     23 * of the triggered virtqueue itself. the preferred approach will be decided
     24 * as we progress and experiment with those two different approaches.
     25 *
     26 * @RP_MBOX_CRASH: this message is sent if BIOS crashes
     27 *
     28 * @RP_MBOX_ECHO_REQUEST: a mailbox-level "ping" message.
     29 *
     30 * @RP_MBOX_ECHO_REPLY: a mailbox-level reply to a "ping"
     31 *
     32 * @RP_MBOX_ABORT_REQUEST: a "please crash" request, used for testing the
     33 * recovery mechanism (to some extent).
     34 *
     35 * @RP_MBOX_SUSPEND_AUTO: auto suspend request for the remote processor
     36 *
     37 * @RP_MBOX_SUSPEND_SYSTEM: system suspend request for the remote processor
     38 *
     39 * @RP_MBOX_SUSPEND_ACK: successful response from remote processor for a
     40 * suspend request
     41 *
     42 * @RP_MBOX_SUSPEND_CANCEL: a cancel suspend response from a remote processor
     43 * on a suspend request
     44 *
     45 * Introduce new message definitions if any here.
     46 *
     47 * @RP_MBOX_END_MSG: Indicates end of known/defined messages from remote core
     48 * This should be the last definition.
