Correct.

The best way to do this is to use the 40bit debug timer, it runs at
983Khz. The gettimeofday() unfortunately is not very accurate.. Its 
supposed to interpolate time between clock ticks but the ep93xx 
Linux port doesn't yet do this(Jesse's NetBSD port does though).

Another option would be to use the TS-7260, the XDIO can create up to
14.7Mhz free running counter.
