The modification to yaffs was just a quick hack to verify, that it works with 
mtd->read(write)_ecc too. As an unexspected result I noticed, that the code 
was faster then. On the other hand I'm not a gcc-guru, but I'm not sure, if 
your code is really faster. :) Therefore you have to compare gcc assembly 
output and the behaviour on your target machine..
