The S3C2440 is possibly the worst timer implementation: it is the only
timer supported by the I-pipe patch not based on clockevents. It seems
this platform is not really maintained.
Also, if you want to port the I-pipe patch to a new board, I would
advise you to start with the I-pipe core patch. The timer handling has
changed a lot.
The code for core-3.2 is available here:
