-Subject: [PATCH 3/3] MIPS: Provide a generic plat_irq_dispatch
-
-For platforms which boot with device-tree or have correctly chained
-all external interrupt controllers, a generic plat_irq_dispatch() can
-be used.  Implement a plat_irq_dispatch() which simply handles all the
-pending interrupts as reported by C0_Cause.
