Recently we are introducing multiple git subtree projects and it is the right time to have a universal script to update various subtrees and replace the dts/update-dts-subtree.sh. update-subtree.sh is a wrapper of git subtree commands. Usage: From U-Boot top directory, run $ ./tools/update-subtree.sh pull <subtree-name> <release-tag> for pulling a tag from the upstream. Or run $ ./tools/update-subtree.sh pick <subtree-name> <commit-id> for cherry-pick a commit from the upstream. Currently <subtree-name> supports dts, mbedtls and lwip.
