    I was in on that discussion and for the Ux500 this patch was the
    outcome:
    http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=6488/1

    It seems to work, mostly, it's based off Nico's orion code and
    just tries to make everything as explicit as possible.

    Uwe has also been onto it I think.

    Yours,
    Linus Walleij
