Implement the --all option to have edbg flash all connected boards with the same firmware.

My implementation gets slow with many boards and using fork or threads might make things unnecessarily complex. This in your Makefile gives better results:

install: $(BIN)
  for d in `edbg -l |grep -- - | cut -f3 -d " "`; do { echo "Programming $$d..." ; edbg -s $$d -e -p -v -f $< ; echo "Done $$d." ; } & done ; wait $$!

So not sure if we still want to merge this. Of course the -a approach is still nice for smaller firmwares.

This is not what this tool is for. The option is really useful for R21 only and that's just not worth expanding the code complexity.

Also, I'm planning on adding support for other EDBG-based boards (Arduino Zero, Atmel-ICE, JTAGICE3 with new firmware, etc) without changing VID and PID defines, and the option makes no sense for heterogeneous environment like this.

As you've discovered, it is better to use scripting to achieve the same result.
