mhh then sorry, I experienced a slow imx nand some time ago, too. The
config ARM_OPTIMZED_STRING_FUNCTIONS helped to improve the speedup. Was
just a try, I never looked deeper into the issue...

The issue was a slow tftp with a 'special' host ethernet card. I never
realize what the real problem was and I don't have this hardware anymore.
