   7           Enable U-Boot's command-line functions. This provides a means
   8           to enter commands into U-Boot for a wide variety of purposes. It
   9           also allows scripts (containing commands) to be executed.
  10           Various commands and command categorys can be indivdually enabled.
  11           Depending on the number of commands enabled, this can add

  18           This option enables the "hush" shell (from Busybox) as command line
  19           interpreter, thus enabling powerful command line syntax like
  20           if...then...else...fi conditionals or `&&' and '||'
  21           constructs ("shell scripts").
