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 cleanup - Unify "Inc" to "Inc." and "LLC." to "LLC" Signed-off-by: Martin Roth <martin@coreboot.org> Change-Id: Ie03a3ce1f6085494bd5f38da76e2467970cf301a Reviewed-on: https://review.coreboot.org/c/coreboot/+/35430 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
