This enables DSP IPC protocol between host AP (Linux)

and the firmware running on DSP.

DSP exists on some i.MX8 processors (e.g i.MX8QM, i.MX8QXP).

It acts like a doorbell. Client might use shared memory to

exchange information with DSP side.

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.

It is possible to use APIs exposed by the SECO like HSM and SHE using the
|
|
|
|
SAB protocol via the shared Messaging Unit. This driver exposes these
|
|
|
|
interfaces via a set of file descriptors allowing to configure shared
|
|
|
|
memory, send and receive messages.
