27  * Mbox events
28  *
29  * The event mechanism is based on a pair of event buffers (buffers A and
30  * B) at fixed locations in the target's memory. The host processes one
31  * buffer while the other buffer continues to collect events. If the host
32  * is not processing events, an interrupt is issued to signal that a buffer
33  * is ready. Once the host is done with processing events from one buffer,
34  * it signals the target (with an ACK interrupt) that the event buffer is
35  * free.
