Even then, there is a lot you can do. For example, U-Boot can detect being
started by a watchdog reset, find out what image was started previously,
mark it
invalid and take the other one.

It is just a matter of how much effort one wants to spend. U-Boot is a
rich boot loader that can easily be extended to your needs.
