IMX DSP is only needed by SOF or any other module that wants to communicate with the DSP. When SOF is build as a module IMX DSP is forced to be built inside the kernel image. This is not optimal, so allow IMX DSP to be built as a module. Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

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.
