That means you'd prefer no output?  Some time ago we even got some more
dots during decompression, I'd like to get these back.

The only downside of these outputs I can imagine is to save the time it
takes to get them out of the serial. But if you really care, you might
want to evaluate the possibility to let U-Boot uncompress your kernel.
(Depending on some parameters of your hardware this might or might not
be faster for you.)
