+ * 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.
