+description: |
+  The MIPS GIC routes external interrupts to individual VPEs and IRQ pins.
+  It also supports local (per-processor) interrupts and software-generated
+  interrupts which can be used as IPIs. The GIC also includes a free-running
+  global timer, per-CPU count/compare timers, and a watchdog.
