Actually it's a way that is limited in many respects, and nearly
always there are better solutions.  If just having one file is
important to you, there are other approaches to acchieve the same.
Using a FIT image with U-Boot would be a very flexible and powerful
way (see doc/uImage.FIT/*), but even a simple multi-file image would
do that, and probably better.

Best regards,
