-Overview
---------
-
-This driver implements the support for Linux of Silicon Labs (Silabs)
-C2 Interface used for in-system programming of micro controllers.
-
-By using this driver you can reprogram the in-system flash without EC2
-or EC3 debug adapter. This solution is also useful in those systems
-where the micro controller is connected via special GPIOs pins.
-
-References
-----------
-
-The C2 Interface main references are at (http://www.silabs.com)
-Silicon Laboratories site], see:
-
-- AN127: FLASH Programming via the C2 Interface at
-http://www.silabs.com/public/documents/tpub_doc/anote/Microcontrollers/Small_Form_Factor/en/an127.pdf, and
-
-- C2 Specification at
-http://www.silabs.com/public/documents/tpub_doc/spec/Microcontrollers/en/C2spec.pdf,
-
-however it 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. Currently
-this code supports only flash programming but extensions are easy to
-add.
-
-Using the driver
-----------------
-
-Once the driver is loaded you can use sysfs support to get C2port's
-info or read/write in-system flash.
-
-# ls /sys/class/c2port/c2port0/
-access            flash_block_size  flash_erase       rev_id
-dev_id            flash_blocks_num  flash_size        subsystem/
-flash_access      flash_data        reset             uevent
-
-Initially the C2port access is disabled since you hardware may have
-such lines multiplexed with other devices so, to get access to the
-C2port, you need the command:
-
-# echo 1 > /sys/class/c2port/c2port0/access
-
-after that you should read the device ID and revision ID of the
-connected micro controller:
-
-# cat /sys/class/c2port/c2port0/dev_id
-8
-# cat /sys/class/c2port/c2port0/rev_id
-1
-
-However, for security reasons, the in-system flash access in not
-enabled yet, to do so you need the command:
-
-# echo 1 > /sys/class/c2port/c2port0/flash_access
-
-After that you can read the whole flash:
-
-# cat /sys/class/c2port/c2port0/flash_data > image
-
-erase it:
-
-# echo 1 > /sys/class/c2port/c2port0/flash_erase
-
-and write it:
-
-# cat image > /sys/class/c2port/c2port0/flash_data
-
-after writing you have to reset the device to execute the new code:
-
-# echo 1 > /sys/class/c2port/c2port0/reset
