The kernel FIFO queue has a couple issues. The biggest issue is that
it causes extra latency in a path that can be used in real-time tasks,
such as communication with real-time remote processors.
The whole FIFO idea itself looks to be a leftover from before

In the next commit we will be adding the M4F driver which shares a lot of
commonality with the DSP driver. Move this shared functionality out so
that it can be used by both drivers.

local reset is only for the M4F processing core. When loading the image,
the driver first releases the subsystem reset, loads the firmware image
and then releases the local reset to let the M4F processing core run.

The YAML binding document provides the various node properties to be

Enable CONFIG_TI_K3_M4_REMOTEPROC
Some K3 platform devices (AM64x, AM62x) have a Cortex M4 core. Build
the M4 remote proc driver as a module for these platforms.
