I have queued patches 1 - 14 of v4 of this series (sorry for missing v5,
but I believe the code is the same) for v3.14.

I made a slight modification to patch 11 ("ARM: shmobile: Remove
non-multiplatform Koelsch reference support") which was to drop the
arch/arm/boot/dts/Makefile portion of the change.

This is because the DT portion koelsch-reference doesn't actually exist in
the boards branch, which seems to be the most relevant place to make this
change. Could you please submit that portion of the patch separately
with a repost of patch 15. I'm quite happy if you squash it all into
one patch.

I have not queued up patches 16 and 17 as I believe they create
what Olof would call a circular branch dependency:


       +------> dt ------+
soc ---+                 +----> soc
       +----> boards ----+

As they just remove stuff I suggest holding them over until v3.15.
