+ Enable this to inhibit loading the environment during board
+ initialization. This can address the security risk of untrusted data
+ being used during boot. Normally the environment is loaded when the
+ board is initialised so that it is available to U-Boot. This inhibits
+ that so that the environment is not available until explicitly loaded
+ later by U-Boot code. With CONFIG_OF_CONTROL this is instead
+ controlled by the value of /config/load-environment.
