Since i don't want that stdout is redirected to LCD (customer isn't
interested in watching
all output of u-boot) i need something to write out of scripts to the

For example we write of script in which mode we are booting, maybe also
some default ip settings
in recovery mode.

Okay, thats right - should we rename it to "lcdputs" ?
Only thing for decission was, that existing commands are allready defined
within
lcd.c. But i've no problem to move it. What do you say? let's move?
