/*

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