      Fix number base handling of "load" command · b770e88a
      Wolfgang Denk authored
      As documented, almost all U-Boot commands expect numbers to be entered
      in hexadecimal input format. (Exception: for historical reasons, the
      "sleep" command takes its argument in decimal input format.)
      
      This rule was broken for the "load" command; for details please see
      especially commits 045fa1e1 "fs: add filesystem switch libary,
      implement ls and fsload commands" and 3f83c87e "fs: fix number base
      behaviour change in fatload/ext*load".  In the result, the load
      command would always require an explicit "0x" prefix for regular
      (i. e. base 16 formatted) input.
      
      Change this to use the standard notation of base 16 input format.
      While strictly speaking this is a change of the user interface, we
      hope that it will not cause trouble.  Stephen Warren comments (see
      [1]):
      
              I suppose you can change the behaviour if you want; anyone
              writing "0x..." for their values presumably won't be
              affected, and if people really do assume all values in U-Boot
              are in hex, presumably nobody currently relies upon using
              non-prefixed values with the generic load command, since it
              doesn't work like that right now.
