+config IMX_SCU
+ bool "IMX SCU Protocol driver"
+ depends on IMX_MBOX
+ help
+ The System Controller Firmware (SCFW) is a low-level system function
+ which runs on a dedicated Cortex-M core to provide power, clock, and
+ resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
+ (QM, QP), and i.MX8QX (QXP, DX).
+
+ This driver manages the IPC interface between host CPU and the
+ SCU firmware running on M4.
