saveenv - save environment variables to persistent storage
Usage:
saveenv
=>
All changes you make to the U-Boot environment are made in RAM only. They are lost as soon as you reboot
the system. If you want to make your changes permanent you have to use the saveenv command to write a
copy of the environment settings to persistent storage, from where they are automatically loaded during
startup:
=> saveenv
