The reason I make a big deal about saveenv is because I use an environment variable ("video-mode") to enable video support. Once the console is switched to the video display, the only way to switch it back to the serial port is to delete the environment variable, save the environment, and reboot.
If we had a command that switched the console back to the serial port, I wouldn't need any of this.
Yes, I noticed it last week when working with mx51evk.
The suggestion I got from the list and that worked for me was to force setenv("stdout", "serial"); inside board_late_init.
