Yes. I really admire you for all your hard work on this. Now that I've 
done a tiny bit here as well. ;)

Unfortunately not all boards print such a message. There is quite a 
range of alternatives, I'm afraid. Some boards use 
CONFIG_AUTOBOOT_STOP_STR, some CONFIG_AUTOBOOT_DELAY_STR. Some print 
this string / char, some don't. So we can't really convert them all into 
such a generic implementation. Without breaking backward (user) 
compatibility. At least I don't see such a way.

Thanks,
Stefan
