There is not need for a bootloader file to create an uninstall firmware so one needs to provide a model. Also cleanup the install script a bit by factoring message into a function, also print them to the log so that the user can report what was printed on the screen easily. The uninstall script is quite trivial, it remounts the rootfs and restores the backed up OF to its right place. Change-Id: I1f5c0efeb965fdc7fe17f45c2753c0f52c34f7f1
