1M baud Optiboot for mighty1284p

oric_dan:
I'm kind of surprised that you guys are able to get 1-Mbaud comms at all.

unless im mistaken stk500 protocol required pretty solid handshaking (wait for sp?) so its not likely to stream continuous. i think that was one of the reasons tests from the freaks fellow showed little benefit to high rates beyond 57k and none over 115k. law of diminishing returns..

but i am suprised 1m or even 115k works for so many people due to hardware issues like cable distortions, clock offsets, etc.. when it works for a particular setup it works, but then somebody else tries and... well...
