- * IRQs on the SEAD board look basically are combined together on hardware
- * interrupt 0 (MIPS IRQ 2)) like:
- *
- * MIPS IRQ Source
- * -------- ------
- * 0 Software (ignored)
- * 1 Software (ignored)
- * 2 UART0 (hw0)
- * 3 UART1 (hw1)
- * 4 Hardware (ignored)
- * 5 Hardware (ignored)
- * 6 Hardware (ignored)
- * 7 R4k timer (what we use)
- *
- * 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
- * another exception, big deal.
