Christian,

here is the pull request [1], pull [2], and stable commitment for the
branch [3]. You can merge that branch too and name the dependency when
you send your PR, arm-soc maintainers will sort it out.

Besides a small section mismatch fixup for nomadik that Olof requested,
I guess it is in.
