K3 AM64x SoC has a Cortex M4F subsystem in the MCU voltage domain.
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.
