| 16 | * Most of the older ColdFire parts use the same simple interrupt |
| 17 | * controller. This is currently used on the 5206, 5206e, 5249, 5307 |
| 18 | * and 5407 parts. |
| 19 | * |
| 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. |
