Any volunteers? If nobody else steps up I'm willing to put some work
into this. I'm a bit reluctant to do this right away since time is
already very short before the 3.8 merge window. If I promise to look at
this once the Tegra DRM driver is in, would people be willing to let it
slip for now?

I know this is not much of an argument and I'm all in favour of a
generic implementation, but I don't think endianess will be an issue in
the near future on Tegra. I don't believe there are any plans to make it
support big endian.
