In linux kernel since version 3.10 (release Date: 2013-06-30)  
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.
