You should continue to develop the code before we commit it to
coreboot. Also, you can read up on git, formatting patches, and
sign-off procedures on the wiki.

http://www.coreboot.org/Development_Guidelines
http://www.coreboot.org/Git

Once you are satisfied with your changes, you can push the to gerrit for review.
