If 'bootefi hello' or 'bootefi selftest' can be executed depends on the configuration.

If an invalid non-numeric 1st argument is passed to bootefi, e.g. 'bootefi hola', this string is converted to 0 and U-Boot jumps to this typically invalid address.

With the patch the online help is shown instead.
