Yes, I understand that. It is also important that the board setup be
compatible which is the responsibility of uboot. Which seems to be
true in your case. None of the Arm chips I've used have this feature.
While they can be dynamically detected without danger, it is just as
easy to make separate u-boot builds for each.
Which chips are you using?
