Mailbox is used by the Rockchip CPU cores to communicate requests to MCU processorm.
This driver is found on RK3368 SoCs.
The Mailbox module is a simple APB peripheral that allows both the Cortex-A53 MCU system to communicate by writing operation to generate interrupt. The registers are accessible by both CPU via APB interface.
Tested on RK3368 SDK board.
