Given the fact that we have exactly one place only where we call lcd_clear() [in lcd_init()], this just adds complexity and memory footprint without adding benefits. Please omit this part.
use the patch 2/2 for the ainsi support

I wonder if there is any user out there who expects that the "cls" command will also draw the logo - I am pretty sure that this is actually a bug introduced when the lcd_clear() code was extracted from lcd_init() in commit 8655b6f8 nearly 5 years ago.
To me the current implementation makes no sense. I suggest to rather fix the origona bug, i. e. move the lcd_logo() call into lcd_init() so it gets done only once, and not when running the lcd_clear() function using the "cls" commandline interface.
so I prefer to remove the cls command and introduce the clear command which will be availlable for all output serial & lcd
