To support xMega AVR #4

urboot for AVR xMega will be interesting.

From here.

I'd be interested in handling XMEGA parts (They have a huge bootloader section that I think could be made available for ordinary applications)

So far the most popular bootloaders for ATxmega seem to be AVR109. For USB bootloaders, then there are Microchip FLIP2 and Caterina (USB to Serial + AVR109). I've also encountered STK500v2 bootloaders.

I have not been able to get any bootloader working yet on my ATxmega32A4U breakout board with FT232RL. I need to try again.
