This makes no sense. If it is ``exactly like "go"'' it doesn't matter
if the code returns or not (and actually this is what I'm  trying  to
point out all the time).

It's just that "go" shall retain the standard U-Boot environment for
application it runs, and that the applications need to take care if
they need to meddle with interrupts, exception handlers, etc.
