[PATCH] Add raspberry pi board BSP

Mon Feb 25 17:21:02 UTC 2013
Our github integration is broken. We have an RTEMS on github, but it
is not getting updated properly. We have a plugin to update
github/RTEMS automatically when we push to git.rtems.org, but the
plugin is not working.
We could maybe create a cron job on the git.rtems.org server to push to github.
