As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Additional changes in this patch: - Make sure files say that they're part of the coreboot project - Move descriptions below the license header - Fix some spacing Signed-off-by: Martin Roth <martin@coreboot.org> Change-Id: Id5f26a73f0df366651c076a94975bce1fb321b70 Reviewed-on: https://review.coreboot.org/c/coreboot/+/34605 Reviewed-by: Werner Zeh <werner.zeh@siemens.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
