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