Hello,

Nice to see support for Blackfin processors!

Maybe make it the default choice when BR2_bfin is enabled ?

That looks strange, if you want uImage, you want uImage, right ? Or is
Blackfin's vmImage in fact a uImage (in which case a short comment
above this condition would be nice).

We are going to move away from this and replace all that stuff by a
free-form text field. Patches have been posted, but haven't been merged
yet. As I am reworking board support and system-level configuration, I
think I'll take care of them.
