/* Define NR_IRQs here, machine specific can always re-define.
* Currently the IRQ_EINT27 is the last one we can have. */
/* Next the external interrupt groups. These are similar to the IRQ_EINT(x)
* that they are sourced from the GPIO pins but with a different scheme for
* priority and source indication.
*
* The IRQ_EINT(x) can be thought of as 'group 0' of the available GPIO
* interrupts, but for historical reasons they are kept apart from these
* next interrupts.
*
* Use IRQ_EINT_GROUP(group, offset) to get the number for use in the
* machine specific support files.
