It seems to be lacking the board support for dm813x-evm.
I will ask the arago guys about it.

But really, since I still have to do kernel and u-boot from scratch, I 
don't think I gain much. (I can't use the original TI stuff.)
I guess if I would grokk how a basic hardware enablement layer is done, 
I would be better off.
