Tested and working on the dig297 board, on top of the master
branch in the u-boot-ti repository.

I also tried to merge your work on the u-boot-arm repo, but it
conflicts with the GPIO work recently committed there. You might
want to rebase and resubmit when the -ti repo will be in line with
the -arm one.

Anyway, for the current version:
