16 * Most of the older ColdFire parts use the same simple interrupt
17 * controller. This is currently used on the 5206, 5206e, 5249, 5307
20 * The builtin peripherals are masked through dedicated bits in the
21 * Interrupt Mask register (IMR) - and this is not indexed (or in any way
22 * related to) the actual interrupt number they use. So knowing the IRQ
23 * number doesn't explicitly map to a certain internal device for
24 * interrupt control purposes.
28 * Define the base address of the SIM within the MBAR address space.
