[chbot] Programming AVRs over USB

[Michael Hope]

Hi there.  This might be interesting to those who are into AVRs but
are parallel port impaired.  It turns out that you can use most any
FTDI based ARM JTAG dongle plus a patch to avrdude to program the
chips.  Performance is decent at about 1 s for a erase/program/verify
cycle on a 1 k program to a MEGA48.

It should also work on any FTDI chip with the MPSSE engine which is
useful if you have one of the FTDI demo boards.

My notes and patches are at:
