Stop me if I'm wrong, but basically this would imply that u-boot be built with support for the largest possible device combination, thus be rather big, right? I hope the ability to trim it down u-boot to a minimum is retained, though, i.e. be able to choose between a one-size-fits-all binary that will run on anything *or* a tight fit that will run only on a given platform with minimal footprint (or anything in-between, actually).
