- * @RP_MBOX_READY: informs the M3's that we're up and running. this is
- * part of the init sequence sent that the M3 expects to see immediately
- * after it is booted.
- *
- * @RP_MBOX_PENDING_MSG: informs the receiver that there is an inbound
- * message waiting in its own receive-side vring. please note that currently
- * this message is optional: alternatively, one can explicitly send the index
- * of the triggered virtqueue itself. the preferred approach will be decided
- * as we progress and experiment with those two different approaches.
- *
- * @RP_MBOX_CRASH: this message is sent if BIOS crashes
- *
- * @RP_MBOX_ECHO_REQUEST: a mailbox-level "ping" message.
- *
- * @RP_MBOX_ECHO_REPLY: a mailbox-level reply to a "ping"
- *
- * @RP_MBOX_ABORT_REQUEST: a "please crash" request, used for testing the
- * recovery mechanism (to some extent).
- *
- * @RP_MBOX_SUSPEND_AUTO: auto suspend request for the remote processor
- *
- * @RP_MBOX_SUSPEND_SYSTEM: system suspend request for the remote processor
- *
- * @RP_MBOX_SUSPEND_ACK: successful response from remote processor for a
- * suspend request
- *
- * @RP_MBOX_SUSPEND_CANCEL: a cancel suspend response from a remote processor
- * on a suspend request
- *
- * Introduce new message definitions if any here.
- *
- * @RP_MBOX_END_MSG: Indicates end of known/defined messages from remote core
- * This should be the last definition.
