title: Marvell ICU Interrupt Controller

description:
  The Marvell ICU (Interrupt Consolidation Unit) controller is responsible for
  collecting all wired-interrupt sources in the CP and communicating them to the
  GIC in the AP. The unit translates interrupt requests on input wires to MSG
  memory mapped transactions to the GIC. These messages access different GIC
  memory areas depending on their type (NSR, SR, SEI, REI, etc).
