* Add support for the Atmel STK600 for "classic" AVRs (AT90, ATtiny,
ATmega), using either ISP or high-voltage programming modes.
* Add support for the -x devcode extended parameter to the avr910
programmer, to allow overriding the device code sent to the
programmer.
Version 5.5:
* Add support for the USBtinyISP programmer (patch #6233)
