+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).
