5  * interrupt controllers with 63 interrupt sources, organized as 56 fully-
6  * programmable + 7 fixed-level interrupt sources. This includes the 523x
10  * The external 7 fixed interrupts are part of the Edge Port unit of these
11  * ColdFire parts. They can be configured as level or edge triggered.
