From: Magnus Damm <damm@opensource.se>

Add Koelsch and r8a7791 to CONFIG_SHMOBILE_MULTI. At this
point CCF is not yet supported so you cannot run this code
yet. For CCF support to happen several different components
are needed, and this is one simple portion that moves us
forward. Other patches need to build on top of this one.

Koelsch board support exists in 3 flavors:
1) SHMOBILE_MULTI, MACH_KOELSCH - board-koelsch-reference.c (CCF + DT)
2) SHMOBILE, MACH_KOELSCH_REFERENCE - board-koelsch-reference.c (DT)
3) SHMOBILE, MACH_KOELSCH - board-koelsch.c (legacy C code)

When CCF is done then 2) will be removed. When 1) includes same features
as 3) then 3) will be removed.

As this part of the patch can't be used without CCF, I'd rather bundle it with 
the CCF patches. I don't like pushing code known to be broken to mainline :-)

Well, this part of the patch can be used while developing CCF. Without
this part you will have to build higher stacks of patches that
includes this feature. And since this portion will contain quite a few
conflicts related to the various boards that will get multiplatform
and CCF in the future I'd like to see just this bit merged ahead of
time. Just to make merge easier. If something is OK to merge without
dependencies then lets merge it. This is how we did it with EMEV2 and
KZM9D.

In the end I guess it's up to Simon since he will do the merge of all
different boards.

If we end up doing it the way I prefer, would it be OK if I submitted
a similar patch for Lager that you can base your next version of
CCF/Multiplatform patches on? =)

Thanks,
