CB:41194 got rid of "this file is part of" lines. However, there are some changes that landed right around the same time including those lines. This change uses the following command to drop the lines from new files: sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool) Signed-off-by: Furquan Shaikh <furquan@google.com> Change-Id: Ic3c1d717416f6b7e946f84748e2b260552c06a1b Reviewed-on: https://review.coreboot.org/c/coreboot/+/41342 Reviewed-by: Patrick Georgi <pgeorgi@google.com> Reviewed-by: Raul Rangel <rrangel@chromium.org> Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
