Oh, i forgot those iMX references, need to fix it, thanks for catching it. Initially i tried to use the existing imx driver, but mainly the ColdFire controller needs all ops/accessors functions to be big endian, and there are other minimal differecies in the controllers. Finally the simpliest way was to create a separate module.
