It would be nice if you could add the exact command lines you used for the different tests so it's easy to run the same tests on other boards as well. I suppose you added some flag to gcc to make use of the floating point hardware in i.MX35?

Could also add information on the RAM characteristics of each board? DDR1/DDR2, 16 bit/32 bit wide, and speed (MHz9.
