The remote processor's life cycle management and IPC mechanisms are similar across the R5F and M4F cores from remote processor driver point of view. However, there are subtle differences in image loading and starting the M4F subsystems. The YAML binding document provides the various node properties to be configured by the consumers of the M4F subsystem.
