- Fix a bug when doing partial updates (Geert Uytterhoeven)

Thanks, the text console is now more or less working as expected.

Thanks for giving it a try to this version too! Glad to know that
is working better now.

There is still an issue with the cursor, though.
After doing "echo hello > /dev/tty0", the text appears, but the cursor
is gone. "clear > /dev/tty0" brings it back.

Hmm, I was able to reproduce this too. Thanks for pointing it out,
I'll investigate what the problem is.
 

The execution time of "time ls" has improved. It now takes 1.21s
(0.86s with ssd1306fb).

Yes, I believe that was due the bug I mentioned that partial updates
weren't done but a full screen update instead.
 

The logo is not shown, even when I create a 16-color or 224-color
version of the small monochrome logo I'm using.

I'll also dig into this.

Best regards,
