   * 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.
