7302a6487SSimon Glass	  Enable U-Boot's command-line functions. This provides a means
8302a6487SSimon Glass	  to enter commands into U-Boot for a wide variety of purposes. It
9302a6487SSimon Glass	  also allows scripts (containing commands) to be executed.
10302a6487SSimon Glass	  Various commands and command categorys can be indivdually enabled.
11302a6487SSimon Glass	  Depending on the number of commands enabled, this can add
