Define this if you don't want to or can't have an environment stored
- on a storage medium. In this case the environemnt will still exist
+ on a storage medium. In this case the environment will still exist
while U-Boot is running, but once U-Boot exits it will not be
stored. U-Boot will therefore always start up with a default
environment.
