The original driver is part of the Freescale's kernel for i.MX, based on
the vanilla kernel 2.6.31. However, the code was not sent to LKML and it
is not part of the kernel mainline.
For this reason and because I dropped a lot of parts that I thought not
useful in u-boot, this porting is not so close to the original one. I
have already tried to fix all code styling issues, but it seems I missed
a lot of them and I have to check them again. And of course, I will add
the reference to the original code, too.

Yes, this was already in my list to drop. I missed it ;-)

No, I will fix them.

A comment in the original code that I cannot understand and I have to
drop ;-)
