-+ * 1 Software (ignored)
-+ * 2 Combined hardware interrupt (hw0)
-+ * 3 Hardware (ignored)
-+ * 4 Hardware (ignored)
-+ * 5 Hardware (ignored)
-+ * 6 Hardware (ignored)
-+ * 7 R4k timer (what we use)
-+ *
-+ * Note: On the SEAD board thing are a little bit different.
-+ * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
-+ * wired to UART1.
-+ *
-+ * We handle the IRQ according to _our_ priority which is:
-+ *
-+ * Highest ---- R4k Timer
-+ * Lowest ---- Combined hardware interrupt
-+ *
-+ * then we just return, if multiple IRQs are pending then we will just take
