OK, I did that, and will send that as a separate series, as it's not
really related to the F1C100 DT changes.

Please disregard patches 13/14 and 14/14 for now.

For the sake of completeness of this thread, this is what I found out:

ARCH_U300 was the only user, and we lost a prerequisite (ARCH_AMBA) when
it was removed, so this symbol cannot be selected anymore.

CONFIG_FB was not selected anymore, when DRM_KMS_FB_HELPER was removed, so
we lost all those drivers. I brought CONFIG_FB in explicitly, as
multi_v7_defconfig did a while ago.

More details in the commit messages of the upcoming series.
