++ * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in

++ * 4 Hardware (ignored)

++ * 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

-+ * 1) We handle one interrupt and return, sitting in a loop and moving across

-+ * 2) We need not check against bits in the status register IRQ mask, that
-+ * would make this routine slow as hell.
-+ *
-+ * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
-+ * between like BSD spl() brain-damage.
-+ *
-+ * Furthermore, the IRQs on the MIPS board look basically (barring software
-+ * IRQs which we don't use at all and all external interrupt sources are

-+ *
-+ * 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
