2 bool "Mailbox Hardware Support"
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.

12 help
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.

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

38 bool "Platform Communication Channel Driver"
39 depends on ACPI
40 help
41 ACPI 5.0+ spec defines a generic mode of communication
42 between the OS and a platform such as the BMC. This medium
43 (PCC) is typically used by CPPC (ACPI CPU Performance management),
44 RAS (ACPI reliability protocol) and MPST (ACPI Memory power
45 states). Select this driver if your platform implements the
46 PCC clients mentioned above.
