- * Change History:
- *
- * $Log: not supported by cvs2svn $
- * Revision 1.7  2008-01-11 10:18:28  marcus
- * Modified interrupt mechanism. Added atomic functions and queues, to address race conditions. Removed unused interrupt code.
- *
- * Revision 1.6  2007-11-04 20:58:22  marcus
- * Added interrupt generator acknowledge.
- * Fixed wrong operator.
- *
- * Revision 1.5  2007-10-31 15:42:21  marcus
- * Added IG ack for testing, may be removed later.
- *
- * Revision 1.4  2007-07-17 13:15:56  marcus
- * Removed Tasklets.
- * Using newest map for the ABB interrupts.
- *
- * Revision 1.3  2007-07-05 15:30:30  marcus
- * Added support for both register maps of the ABB.
- *
- * Revision 1.2  2007-05-29 07:50:18  marcus
- * Split code into 2 files. May get merged in the future again....
- *
- * Revision 1.1  2007/03/01 16:57:43  marcus
- * Divided driver file to ease the interrupt hooks for the user of the driver.
- * Modified Makefile accordingly.
