This is a pretty important point. We've come a long way in U-Boot to
make it such flexible and configurable - note: run-time configurable
by the user. Many of us have too many times before been p*ssed off by
some stupid loader which was hardwaired to 115 kbps when you just had
an old terminal server or modem that maxed out at 38 kbps, etc. The
flexibility that is built into current U-Boot may be one of the
causes for it's complexity, but it is also a very strong point.

Instead of simply throwing such things over board I ask for
constructive discussion how to adapt them to a new, better design.

Best regards,
