Hopefully you will be proven wrong here. Thanks for all the rework.

Seems that we now have two versions of the DaVinci patches. I suggest to use 
your patches for inclusion instead of Dirk's, because you are the original 
author. Dirk is welcome to send some review comments and/or 
Acked-by/Signed-off-by lines of course.

Here one comments from myself (I have to admit that the inline patches make 
the review a lot easier for me, since I'm sometimes just to lazy do it with 
attached compressed patches ;)):

I noticed that you have one board directory "board/davinci". And from my 
understanding (I'm no DaVinci expert at all) a lot of CPU (SoC) code is 
included in this board directory. Stuff like nand-driver or lowlevel_init 
seem quite cpu-specific. Please correct me if I'm wrong here. But if my 
finding is correct, I would like to seem some of this cpu-specific stuff 
moved into the cpu directory and perhaps rename the board directory into 
something not that generic as "board/davinci". We usually name the board 
directory according to the name of the board itself. You are supporting 3 
different boards in this board directory right now. This makes it difficult 
to pick a name for such a board directory. But when more and more DaVince 
port will emerge, it will not be possible anymore to support them all in one 
board directory. It should be one board directory per board. Only *very* 
similar board should share a board directory.

So I suggest to create 3 separate board directories and try to move the 
generic, cpu-specific stuff in the cpu directory.

What do you think? Does this make sense?

Thanks.

Best regards,
Stefan
