+       bool "Mailbox Hardware Support"
+       help
+         Mailbox is a framework to control hardware communication between
+         on-chip processors through queued messages and interrupt driven
+         signals. Say Y if your platform supports hardware mailboxes.
+
+if MAILBOX
+
+config ARM_MHU
+       tristate "ARM MHU Mailbox"
+       depends on ARM_AMBA
+       help
+         Say Y here if you want to build the ARM MHU controller driver.
+         The controller has 3 mailbox channels, the last of which can be
+         used in Secure mode only.
+
+config PL320_MBOX
+       bool "ARM PL320 Mailbox"
+       depends on ARM_AMBA
+       help
+         An implementation of the ARM PL320 Interprocessor Communication
+         Mailbox (IPCM), tailored for the Calxeda Highbank. It is used to
+         send short messages between Highbank's A9 cores and the EnergyCore
+         Management Engine, primarily for cpufreq. Say Y here if you want
+         to use the PL320 IPCM support.
+
+config OMAP2PLUS_MBOX
+       tristate "OMAP2+ Mailbox framework support"
+       depends on ARCH_OMAP2PLUS
+       help
+         Mailbox implementation for OMAP family chips with hardware for
+         interprocessor communication involving DSP, IVA1.0 and IVA2 in
+         OMAP2/3; or IPU, IVA HD and DSP in OMAP4/5. Say Y here if you
+         want to use OMAP2+ Mailbox framework support.
+
+config OMAP_MBOX_KFIFO_SIZE
+       int "Mailbox kfifo default buffer size (bytes)"
+       depends on OMAP2PLUS_MBOX
+       default 256
+       help
+         Specify the default size of mailbox's kfifo buffers (bytes).
+         This can also be changed at runtime (via the mbox_kfifo_size
+         module parameter).
+
+config PCC
+       bool "Platform Communication Channel Driver"
+       depends on ACPI
+       help
+         ACPI 5.0+ spec defines a generic mode of communication
+         between the OS and a platform such as the BMC. This medium
+         (PCC) is typically used by CPPC (ACPI CPU Performance management),
+         RAS (ACPI reliability protocol) and MPST (ACPI Memory power
+         states). Select this driver if your platform implements the
+         PCC clients mentioned above.
+
+config ALTERA_MBOX
+       tristate "Altera Mailbox"
+       help
+         An implementation of the Altera Mailbox soft core. It is used
+         to send message between processors. Say Y here if you want to use the
+         Altera mailbox support.
