| 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. |
