This is not correct. It is at least supported on 8xx, 8260 and 5200, and easy to add to other processors.
CPM SCC (or equivalent by writing bootcount_load() and bootcount_store() functions) and is too simplistic for what I need to do. It might work if the OS (after boot) could update the U-Boot Environment, but that's way too much linking (between Linux and U-Boot) and I don't have a writeable environment either.
