File update_git.sh of Package u-boot

#!/bin/bash
#
# Instead of a quilt workflow, we use a git tree that contains
# all the commits on top of a stable tarball.
#
# When updating this package, just either update the git tree
# below (use rebase!) or change the tree path and use your own
#
# That way we can easily rebase against the next stable release
# when it comes.
