C2 port implements a two wire serial communication protocol (bit banging) designed to enable in-system programming, debugging, and boundary-scan testing on low pin-count Silicon Labs devices.
Main references are at Silicon Laboratories site:
* AN127: FLASH Programming via the C2 Interface http://www.silabs.com/public/documents/tpub_doc/anote/Microcontrollers/Small_Form_Factor/en/an127.pdf
* C2 Specification http://www.silabs.com/public/documents/tpub_doc/spec/Microcontrollers/en/C2spec.pdf
Currently this code supports only flash programming through sysfs interface but extensions shoud be easy to add.
I know that this (proposal) patch may be incomplete but I'd like to know what you are thinking about it before continuing further. For example I'd like to know if should I put the C2 port core here or into proper subdirectory of linux/drivers/misc/ where clients can be placed also.
Thanks for your suggestions,
Rodolfo
