title: Amlogic Meson AO ARC Remote Processor

description:
  Amlogic Meson6, Meson8, Meson8b and Meson8m2 SoCs embed an ARC core
  controller for always-on operations, typically used for managing
  system suspend. Meson6 and older use a ARC core based on the ARCv1
  ISA, while Meson8, Meson8b and Meson8m2 use an ARC EM4 (ARCv2 ISA)
  core.
