   4           Mailbox is a framework to control hardware communication between
   5           on-chip processors through queued messages and interrupt driven
   6           signals. Say Y if your platform supports hardware mailboxes.

  13           An implementation of the ARM PL320 Interprocessor Communication
  14           Mailbox (IPCM), tailored for the Calxeda Highbank. It is used to
  15           send short messages between Highbank's A9 cores and the EnergyCore
  16           Management Engine, primarily for cpufreq. Say Y here if you want
  17           to use the PL320 IPCM support.

  41           Specify the default size of mailbox's kfifo buffers (bytes).
  42           This can also be changed at runtime (via the mbox_kfifo_size
  43           module parameter).
