interrupt handling in 7410+64260

Its been a little while since I've looked at the GT64260 manual,
but I believe you configure the MPP pins as interrupt pins.  These
then are masked/seen via the GPP_INTR_CAUSE (0xf108) and
GPP_INTR_MASK (0xf10c) registers.  Then, I believe that somewhere in
the CPU's mask, you can enable/disable the GPP/MPP interrupts.

This is what I recall from memory, but hopefully it'll get you
