It would be a much better investment in time if you come up with
patches that help to _avoid_ usign this horrible function, and
eventually removig it from U-Boot.

change_bit() is inherently not portable and actual behaviour is
largely undefined, so please do NOT use this function in any new code.


Best regards,
