    SubjectSupport for Silicon C2 Interface.
    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
