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