6 This enables DSP IPC protocol between host AP (Linux)
7 and the firmware running on DSP.
8 DSP exists on some i.MX8 processors (e.g i.MX8QM, i.MX8QXP).

18 The System Controller Firmware (SCFW) is a low-level system function
19 which runs on a dedicated Cortex-M core to provide power, clock, and
20 resource management. It exists on some i.MX8 processors. e.g. i.MX8QM
21 (QM, QP), and i.MX8QX (QXP, DX).

23 This driver manages the IPC interface between host CPU and the
24 SCU firmware running on M4.
