Nice

I would suggest splitting this change out into a separate patch, or
folding it into the one that creates the ux500.S file.

Did you forget to pass '-M' to git-format-patch?

You can set 'git config diff.renames true' to get this right in the future.

Was this meant to have been in a different patch? I don't see what it does here.
