| mem md: bail out without arguments
|
| Without arguments the 'md' command defaults to show address 0 which
| likely results in a NULL pointer exception, so only three keystrokes
| are necessary to crash barebox. Show usage instead if 'md' is invoked
| without arguments, so that it at least requires an address to be given
| to crash barebox. This increases the stability of barebox by 66%. Hurray!
barebox does not crash any longer when a plain 'md' without additional arguments
is exectuted. However, doing a 'md -s /dev/nor0' was a standard usecase which now
does not work anymore.
