I agree with Tim's recommendation. Using Thomas' patch it is
much easier to port ecos to an other AT91 based board.

We did on original port with ecos 1.3.1... and it was 'painful'.
With the new 'var' architecture, it is straight forward ( a big
thanks to Thomas!).

'hope his modifs are soon in the cvs.
