The remoteproc interface

The remoteproc interface enables developers to interact with the Remote Processor Framework of the Linux kernel, typically allowing them to upload firmware to a SoC embedded microcontroller.

Modern ARM-based silicon contain have additional Cortex M4 or M7 based microcontrollers within the SoC.

This interface allows a snap to load a firmware to such microcontrollers via a snap, and permits the microcontroller to be started and stopped.
