This is the second step to simplify and decrease the default environment for the keymile boards. The release usecase formaly used to set the production environment was removed and the default configuration is now the production environment. So the formar environment variable "release" which has done a lot of things in the past, simply erase the current environment and do a reset which forces u-boot to setup the default environment again.
