You are right in many cases, but on the other hand especially in the
embedded market there are lots of systems which should definitivly NOT
boot every code provided. Just some examples:

- automotive control units: Think about cars being on the highway with
many fancy features built into their electronics (from their owners),
which unfortunately are a security risk for the owner and others on the
road. If a major accident is caused by modified car control software,
who will be sued in the first run? The owner (already dead?)? Or the car
manufacturer who made the system open to changes from everyone?

- medical equipment: Think what nice features could be implemented into
these many machines located in the emergency room... Accessible to any
person who comes by.

My personal believe is that there are many examples of embedded systems,
that should only execute software that has been carefully tested.

And I don't like the idea to see this area as non-compatible with free
software like U-Boot, Linux and others.
