+menuconfig MAILBOX
+ 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.
