2023-06-19build/boot/roms: Support removing microcodeLeah Rowe
From now on, the following rules are available for all mainboards, in resources/coreboot/boardname/board.cfg: * blobs_required="n" or "y" * microcode_required="n" or "y" The blobs setting, if set to "n", simply renames filename.rom to filename_noblobs.rom. The microcode setting, if set to "n", copies the ROM (with or without _noblobs) to filename_nomicrocode.rom (if blobs="n", it would be filename_noblobs_nomicrocode.rom). Where "nomicrocode" is set, ROMs with microcode will still be provided by lbmk and in relesase, but ROMs will also be provided alongside it that lacks any microcode updates. If the *original* ROM already lacks microcode updates, then the original ROM will be *renamed* to include "nomicrocode" in the name. This is done on images for ARM platforms, for instance, where microcode is never used whatsoever. Example filenames now generated: seabios_e6400_4mb_libgfxinit_corebootfb_noblobs_nomicrocode.rom seabios_e6400_4mb_libgfxinit_corebootfb_noblobs.rom seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak_nomicrocode.rom seabios_withgrub_hp8300usdt_16mb_libgfxinit_corebootfb_colemak.rom uboot_payload_gru_kevin_libgfxinit_corebootfb_noblobs_nomicrocode.rom A vocal minority of people were not happy with some of the changes made in Libreboot last year, including on existing supported hardware from before those changes were made. I did this before the last release, out of respect: https://libreboot.org/news/gm45microcode.html (re-add mitigations for no-microcode setup on GM45) This new change is done as an further, extended courtesy. Tested and works fine. (testing using cbfstool-print) Actual Libreboot policy about binary blobs is nuanced. See: https://libreboot.org/news/policy.html (reduction policy) and: https://libreboot.org/freedom-status.html (implementation) Well, the status page talks about descriptor vs non-descriptor on Intel platforms, and where me_cleaner is used (on platforms that need Intel ME firmware), it regards the descriptored setups to be blob-free if coreboot does not require binary blobs. In this paradigm, microcode updates are not considered to be binary blobs, because they aren't technically software, they're more like config files that just turn certain features on or off within the CPU. However, for lbmk purposes, "noblobs" means that, after the ROM is fully ready to flash on the chip, there will be no blobs in it (except microcode). So for example, an X200 that does not require ME firmware is considered blob-free under this paradigm, even though Libreboot policy regards X230 as equally libre when me_cleaner is used; in this setup, ROMs will not contain "blobfree" in the filename, for X230 (as one example).

2023-06-13Revert "Remove most of Ferass's lbmk contributions"Leah Rowe
This reverts commit a4ea2867319471d9fe7d4ee540881e0286b4d3cf. The licensing audit has been abandoned. I will not be re-licensing in bulk to MIT. I can still use MIT license on new works, e.g. utilities, but there's really no pressing need to re-license lbmk. It's just shell scripts, and most of what it interacts with (coreboot, grub, seabios) is GPL anyway. So who cares? Ferass's patch was removed due to refusal to re-license, but the decision to re-license has been canceled. I'm now aiming for a quick stable release.
2023-05-27Remove most of Ferass's lbmk contributionsLeah Rowe
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.

2023-05-09seabios: do normal config, disable oprom in vgaromLeah Rowe
previously, "normal" initmode relied on the vgarom-based seabios config, which enables option roms, but then lbmk would insert pci-optionrom-exec 0 for vgarom, and 2 for normal in libreboot, coreboot roms with "vgarom" in the filename do pci option rom execution from coreboot, and "normal" roms do execution from seabios(where seabios is the only payload provided on normal setups) this is because payloads like grub can also be used, on vgarom setups, where coreboot must handle oprom execution

2022-12-10build/roms: Support using "u-boot" ELF file as U-Boot payloadAlper Nebi Yasak
U-Boot runtime configuration is done with a device-tree file, which is built alongside the executable in the upstream build system, and must be available to U-Boot at runtime. This device-tree is normally not linked into the default "u-boot" ELF file. So far we have been handling it by re-creating a "u-boot.elf" from the raw binary parts by setting REMAKE_ELF, and using that as the coreboot payload. Unfortunately, that fails to build for x86 boards, more specificly the "coreboot" boards upstream. It's also possible (but discouraged) to set OF_EMBED to embed the device-tree file into the U-Boot itself, in which case we could use the "u-boot" file as the payload on the "coreboot" boards. Add support for using the "u-boot" file as the payload if "u-boot.elf" doesn't exist. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>

2022-12-05remove logic for avoiding nonredistributable blobsLeah Rowe
the --nuke option in ifdtool will be used instead, to nuke the ME regions in specific rom sets (and cbfstool will be used to delete mrc.bin files from rom sets) the new method being implemented is heavier on disk io, but simplifies lbmk, and disk io could still be optimised in the following ways: * when copying roms from boards with ME in them, use ifdtool --nuke to get filename.rom.new, and *move* (not copy) filename.rom.new to the new destination (for use with tar) * possibly modify ifdtool to make efficient use of mmap for disk i/o; it currently loads entire roms into an allocated buffer in memory

2022-11-22build/roms: remove seabios_grubfirst logicLeah Rowe
the intended use-case scenario was one in which vga rom initialisation would be used, on desktop configurations, but without coreboot itself handling vga rom initialisation, instead leaving that task to seabios it was assumed that grub, when running on the bare metal with build option "--with-platform=coreboot" would be able to display like this, but it is not so when tested in such setups (add-on gpu with grub payload), it is necessary to extract the video bios and insert it into the coreboot rom, having coreboot handle such execution. this is beyond the scope of lbmk, in context of automated building, because we cannot reliably predict things such as PCI IDs do away with this build option entirely, for it does not serve the intended purpose. it will be necessary to run PC GRUB instead (build option --with-platform=i386-pc). PC GRUB can still read from CBFS, and you could provide it as a floppy image file inside CBFS for SeaBIOS to execute. in this setup, GRUB would function as originally intended by the seabios_withgrub option; such a configuration is referred to as "SeaGRUB" by the libreboot project, and experimentation was done with it in the past, to no avail it's better to keep things simple, in the libreboot project. simpler for users, that is

2022-08-28build/roms: Rebuild cbutils module before starting coreboot buildAlper Nebi Yasak
In recent coreboot versions, running distclean started to erase the cbfstool binary we built earlier in the util/cbfstool dir via the cbutils build script call. The coreboot build puts it in a different directory, and the roms build script can't find it when trying to add payloads to the roms. This doesn't make the script fail (because set -e is stupid like that), and the build appears to succeed if you don't look close enough to see the "cbfsutil not found" error. Build the coreboot utils we want at the places we want them after calling distclean, so that we can actually use cbfsutil and avoid silently-broken roms with newer coreboot versions.

2022-08-28build/roms: Support using U-Boot as a coreboot payloadAlper Nebi Yasak
This enables embedding U-Boot into the coreboot roms as the payload. For now, the ELF file generated by enabling CONFIG_REMAKE_ELF is used, which includes the U-Boot binary and the board-specific device-tree file. It might be better to use the FIT payload support for U-Boot, but that was reportedly broken and is not tested yet. Coreboot boards can specify payload_uboot="y" in their board.cfg to enable building a rom with U-Boot as the payload, which is built from the U-Boot board with the same name. Boards can further specify a uboot_config option, to choose which board-specific config file U-Boot should be built with. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
