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. Signed-off-by: Martin Roth <martin@coreboot.org> Change-Id: I4c9351652d81040cc4e7b85bdd1ba85709a74192 Reviewed-on: https://review.coreboot.org/c/coreboot/+/35178 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
