Remove most of Ferass's lbmk contributions The primary purpose of my intense auditing has been to improve lbmk's coding style and fix bugs but there is a secondary purpose: know precisely who owns what, because I want to re-license as much as possible of lbmk under *MIT*, instead of the current GNU licensing. MIT is vastly superior, because it grants *actual* freedom to the user, permits *sublicensing* and it is vastly more compatible with other GPL combinations; for example, MIT license is compatible with GPL2-only whereas lbmk's current mix of GPLv3-or-later and GPLv3-only is legally incompatible with GPLv2-only. Re-licensing under MIT will most likely result in more contributions to Libreboot's build system in the future, especially as it will attract a lot more commercial interest. Contrary to the popular arguments, copyleft is a liability to the free software movement and results in less code being written; in practise, permissively licensed code gets more public contributions, including from commercial entities, even if companies can theoretically make something proprietary out of it (in practise, anyone inclined can just use the upstream and proprietary forks almost always die). Copyleft propaganda is fundamentally flawed. See: <https://unixsheikh.com/articles/the-problems-with-the-gpl.html> Anyway, I've been doing a combination of: * Seeking permission from other copyright holders, for re-licensing * Deleting, or moving, other contributions; for example, splitting certain contributions into separate files so that originally modified files become unencumbered. This latter solution is a result of *code cleanup* arising from the audit. For Ferass's contributions, I opted to seek *permission*, and permission was denied. In full compliance with this legal imperative, I'm acting accordingly; this commit removes all of Ferass's changes that converted lbmk to posix shell scripts, thus removing his copyright on the affected files, bypassing his authority entirely. Therefore, lbmk is largely now bash-dependent. In practise, nobody is going to use anything other than a GNU system to build Libreboot, because many projects that Libreboot makes use of rely heavily on GNU; for example, coreboot's build system makes heavy use of GNU-specific extensions in *GNU Make*, and likely contains many bashisms. Of course, Libreboot also compiles GNU GRUB. I would much rather have MIT-licensed Bash scripts than GPL-licensed posix SCL scripts. This reverts the changes from Ferass El Hafidi, for the following commits, with some exceptions: * 7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9 * f787044642236917c9c4dbcaa48a6b0648097db0 Exception: download/mrc not reverted, because that was already a fork of an existing script under coreboot's build system, and their script was GPLv2. i cannot/will not re-license this file (ergo, 7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9 change remains intact, on this file) resources/scripts/build/boot/roms_helper, these changes have been kept: * 7e6691e9 - Add ARMv7 and AArch64 support * dec2d720 - add myself in the build/roms_helper script (added 2021 copyright for the change below) * b7405656 - Workaround for grub's slow boot ^ these changes will be re-factored, splitting them out of the file into a new file. This will be done in a future lbmk revision. (in some cases, it makes sense to keep a change but split it, allowing the main file to be re-licensed without the change in it) This is part of a much larger series of licensing audits. It's likely that lbmk will be posix-compliant (in its shell scripts) again some day, because I'm planning to rewrite most of these scripts (the ones modified in this patch), and many of them (e.g. individual download scripts) are subject to future deletion in a planned overhaul of the download logic for third party projects. In addition: these changes are being kept (no attempt to re-license them will be made): * cff081c6 - Fix grub's slow boot (1 year, 5 months ago) <Vitali64> * 4c851889 - Add macbook*1 16mb configs (1 year, 6 months ago) <Vitali64> Ferass's work that remains will be split into dedicated files containing them, where feasible. In the case of grub.cfg (for GNU GRUB), I don't care because it's a script for an engine (GRUB shell) that's under GPL anyway, so who really cares about MIT license.
