Details:

At http://www.mikrocontroller.net/topic/73196 and
http://www.mikrocontroller.net/articles/AVR_Bootloader_FastBoot_von_Peter_Dannegger
exists an implementation of a serial bootloader for a wide range of 8-bit
Atmel devices.

The attached patch adds support to program this devices with avrdude over a
serial line. It should work on linux and windows. I plan to implement the
one-wire mode later.

A complete call for programming might look like:
avrdude -c pedabl -p m8 -P /dev/ttyUSB0 -b 57600 -U flash:w:main.hex -x
"reset_cmd=\nR\n" -x "reset_baud=9600"

The last two extended options are optional and are used to automatically reset
the device for programming.

The bootloader does not support uploading the program to the pc therefore the
verify procedure has to be change in avrdude. To verify a program it has to be
sent to the device again but this time the device checks it itself against the
flash and returns a status code.
