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: I2f350cc3008b17516b5a42cdf07e28d2da5995e9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/35179 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>
