/*
* enum - Predefined Mailbox Messages
*
* @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).
