Benchmarks

[Simon Pickering]

Oops. I took a look at your page of results, and noticed that the 
OMAP2420 didn't really perform all that well at floating point tests, 
despite its having a hardware VFP (vector floating point) unit.

It then dawned on me that although I'd compiled nbench with hardware 
fp, it had been linked against a soft-float libm.

If nothing else, comparing the differences between these new results 
and the ones I previously posted shows how much of a difference the 
floating point libm  makes.

So here are the new results with everything hardware floating point 
(I've also flashed an updated image since I posted the other results, 
but that should make little difference):
