15   It also supports local (per-processor) interrupts and software-generated
16   interrupts which can be used as IPIs. The GIC also includes a free-running
17   global timer, per-CPU count/compare timers, and a watchdog.

69       MIPS GIC includes a free-running global timer, per-CPU count/compare
70       timers, and a watchdog. Currently only the GIC Timer is supported.
