| 3 | * This routine installs an interrupt vector using the basic |
---|
| 4 | * RTEMS mechanisms. This implementation should be suitable for |
---|
| 5 | * most m68k based boards. However, if the board has an unusual |
---|
| 6 | * interrupt controller or most somehow manipulate board specific |
---|
| 7 | * hardware to enable/disable, mask, prioritize, etc an interrupt |
---|
| 8 | * source, then this routine should be customized to support that. |
