Sorry, as I mentioned I had received a patch similar to
yours and I had already merged that patch. I did not
notice that your patch also modified the A20-SOM
where as the patch I merged did not.

I've added the A20-SOM part of your patch (with you
as the author) to my tree now and will include it
in my next pull-req.

Regards,

Hans
