description: |
  Some K3 family SoCs have Arm Cortex M4F cores. AM64x is a SoC in K3
  family with a M4F core. Typically safety oriented applications may use
  the M4F core in isolation without an IPC. Where as some industrial and
  home automation applications, may use the M4F core as a remote processor
  with IPC communications.
