Just one script. Just one! Well, two, but the 2nd one already existed: logic in update/project/trees and update/project/repo was merged into include/git.sh and update/project/build was renamed to update/project/trees; an -f option was added, which calls the functions under git.sh so git clones are now handled by the main build script (for handling makefiles and defconfigs) but the logic there is a stub, where git.sh does all the actual heavy lifting this cuts the file count down by two, and reduces sloccount a reasonable amount because much of the logic already exists in the build script, when it comes to handling targets. git.sh was adjusted to integrate with this, rather than act standalone Signed-off-by: Leah Rowe <leah@libreboot.org>
