Jonas Gorski b751b5893c brcm2708: make it boot on revision 2 raspberry pis
* update the bootcode.bin to the newest version
    - gpu/cpu mem split is now configured through config.txt, so no need
      to create more than one sd card image (just edit the config.txt)
    - bootcode.bin now supports the never revision 2 raspberry pis

  * add a commented prepopulated config.txt for easier config changes
    Taken from <https://github.com/Evilpaul/RPi-config>
