[U-Boot] [PATCH] Make TFTP Quiet

[Robin Getz]

From bca49fb5e3045bc175e924999a4015804c39c5c6 Mon Sep 17 00:00:00 2001
From: Robin Getz <rgetz at blackfin.uclinux.org>

I was using this when I was looking at some other recent tftp performance, 
and thought I would share. I really don't think it belongs, as it is
(a) trivial and (b) mostly debug... (but I'm trying out some more things
with git).

This adds the ability to make tftp a little quieter, which saves some
time printing hash marks on the console. It also has the ability to
print some download stats for debugging network issues.
