   3         help
   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.

  14           Say Y here if you want to build the ARM MHU controller driver.
  15           The controller has 3 mailbox channels, the last of which can be
  16           used in Secure mode only.

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

  32           Mailbox implementation for OMAP family chips with hardware for
  33           interprocessor communication involving DSP, IVA1.0 and IVA2 in
  34           OMAP2/3; or IPU, IVA HD and DSP in OMAP4/5. Say Y here if you
  35           want to use OMAP2+ Mailbox framework support.

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

  50           ACPI 5.0+ spec defines a generic mode of communication
  51           between the OS and a platform such as the BMC. This medium
  52           (PCC) is typically used by CPPC (ACPI CPU Performance management),
  53           RAS (ACPI reliability protocol) and MPST (ACPI Memory power
  54           states). Select this driver if your platform implements the
  55           PCC clients mentioned above.

  60           An implementation of the Altera Mailbox soft core. It is used
  61           to send message between processors. Say Y here if you want to use the
  62           Altera mailbox support.
