+         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.

+       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.
