+Subject: [PATCH 4/5] MIPS: BCM63XX: wire up BCM6358's external interrupts 4
+ and 5
+
+Due to the external interrupts being non consecutive, the previous
+implementation did not support them. Now that we treat both registers
+as separate irq controllers, there is no such limitation anymore and
+we can expose them for drivers to use.
