- * NOTE: LoCoMo has a 1 to many mapping on all of its IRQs.
- * that is, there is only one real hardware interrupt
- * we determine which interrupt it is by reading some IO memory.
- * We have two levels of expansion, first in the handler for the
- * hardware interrupt we generate an interrupt
- * IRQ_LOCOMO_*_BASE and those handlers generate more interrupts
- *

- * IRQ_LOCOMO_LT_BASE
- * IRQ_LOCOMO_SPI_BASE
- * IRQ_LOCOMO_KEY_BASE reads LOCOMO_KIC & 0x0001
