  15 * Mbox events
  16 *
  17 * The event mechanism is based on a pair of event buffers (buffers A and
  18 * B) at fixed locations in the target's memory. The host processes one
  19 * buffer while the other buffer continues to collect events. If the host
  20 * is not processing events, an interrupt is issued to signal that a buffer
  21 * is ready. Once the host is done with processing events from one buffer,
  22 * it signals the target (with an ACK interrupt) that the event buffer is
  23 * free.
