grub.cfg: Add copyright header. The GNU Boot project merged several repositories in its main git repository, each with their separate histories. So far we have: - the documentation/website that came from Libreboot - the documentation/website pictures that also came from Libreboot - the build system that also came from Libreboot (it's called lbmk there). - some website autotools build system that was made from scratch by me. The grub.cfg we use comes from the build system repository (lbmk). I extracted the copyrights from the git commits of this repository. However the first commit of lbmk (which we also have in our main GNU Boot repository) is the following: commit 89517ed6b9e89321e1387ed8f534d7f080ffdf57 Author: [Leah Rowe] Date: [2021] libreboot! this is forked from the "libre" branch in osboot, which is itself a libre, deblobbed fork of osboot, a blobbed up fork of libreboot libreboot needed to be purged clean. this is the new libreboot development repository. the old one has been abandoned So I had to continue and look at the libre branch of osboot and extract the copyrights from its commits as well. Then I downloaded osbmk (https://notabug.org/osboot/osbmk) and continued to look. And here too we need to go beyond the first commit again, because osbmk is based on 'Libreboot 20160907': commit df76c3eb63dd8f4979d78ca262218eedb93512ed Author: [Leah Rowe] Date: [2020] Fork Libreboot 20160907 build system. Large parts have been re-written. This build system builds ROMs for X230, but they are so far untested. Use at your own risk! I still need to write documentation and do testing. SOON: T60 with ATI GPU We can find Libreboot 20160907 in https://notabug.org/libreboot/obsolete-repository-preserved-for-historical-purposes And then we end up with this commit: commit cee90ae0fce6d6aee8d78969b60c952c8890abd6 Author: [Leah Rowe] Date: [2014] Libreboot release 6 beta 1. Before that Libreboot only had tarball releases and the very first tarball release was based on build scripts/Makefiles made by me, and the git repository having the GRUB configuration can be found in Libreboot 20131212 in X60/build-makefiles. commit 80c37b9093be8325bf9ca8271ae4c6dba8fe81d6 Author: [GNUtoo] Date: [2013] Initial commit. For now we only build the grub payload. Signed-off-by: [GNUtoo] And the intial grub.cfg was made by hand by me. While I was at it I also updated the name/email combination in the copyright header for the ones currently used.
