seems like a change that should be by itself, or squashed into the "core bf60x 
support" patch

should be part of the "bf60x dma" patch

these are about the only changes that should be in this patch, and the subject 
should be:
	Blackfin: rsi: add support for bf60x

merge the rsi patch first, then squash this into the bf609-ezkit board patch
