2023-05-27blobutil: merge with main scriptLeah Rowe
make blobutil a symlink. Example of command changes: ./blobutil download x220_8mb is now: ./update blobs download x220_8mb The old command still works, for compatibility. Signed-off-by: Leah Rowe <leah@libreboot.org>
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.

2023-05-14blobutil/inject: use x86 top-aligned mrc offsetLeah Rowe
the old code was specifing an absolute offset for insertion of mrc.bin - cbfstool interprets anything above 0x80000000 as top-aligned memory address in x86, and anything below as an obsolute offset in the flash, like with the old number where a top-aligned address is provided to cbfstool, the absolute position is calculated for the flash, and cbfstool inserts it in the correct rom location the benefit of this change is that the absolute offset is now calculated automatically, which means that the code will be correct even if the flash size changes. for example, if 16MB flash is used whereas 12MB is currently the default an support haswell hardware coreboot does not provide anything readably like Kconfig, for extracting this value. it's baked into the source code of coreboot, so you have to find it. the correct location is hardcoded for each platform, and always the same on each platform, regardless of mainboard

2023-05-14blobutil/inject: massively improved coding styleLeah Rowe
top-down function order, with specific functions for each type of blob. startup logic moved into main(), also split into smaller functions "write one program that does one thing well" blobutil is like that, and has this added philosophy: "write one function that does one thing well" during the course of this re-factoring, several bugs and issues were found, that are pre-existing. these will be corrected in follow-up revisions

2023-04-15blobutil: support fetching KBC1126 EC (HP laptops)Leah Rowe
This is useful for e.g. HP EliteBook 2560p. In coreboot config, enable e.g. (for lbmk blobutil): CONFIG_KBC1126_FW1="../../ec/hp2560p/ec.bin.fw1" CONFIG_KBC1126_FW2="../../ec/hp2560p/ec.bin.fw2" In resources/blobs/sources you would have these entries: EC_url EC_url_bkup EC_hash
2023-04-14blobutil: support extracting ME from full ROMsLeah Rowe
In cases where the vendor update file contains a full ROM image encompassing IFD+GbE+ME+BIOS, blobutil was saving the *entire* ROM containing those, as me.bin. For example, if it's an 8MB ROM, blobutil would create a me.bin file that is actually the whole ROM containing: * Vendor IFD region * Vendor GbE(if it has one) * Vendor ME region * Vendor BIOS region This fix tries with -M and -O first. In this combination, me_cleaner shall extract me.bin (neutered) and save it. If that fails, then the normal method with just -O is tried, which by this logic would always be a lone ME image if it succeeds. I tested downloading ME images on existing boards with this, and it didn't break them, and this fixes the bug. This is done for HP 8200 SFF which Riku_V is adding to lbmk. I'm on IRC with Riku_V as I write this commit message! Super hot hotfix patch.

2023-04-01blobutil: don't hardcode pathsLeah Rowe
2023-04-01blobutil/download: don't hardcode me.bin pathsLeah Rowe
Bruteforce it. Some executables are just using inno archival but some are simple LZMA. This patch handles both of them, and also the event where you have LZMA compressed files (even LZMA compressed files within LZMA compressed archives) within any inno/lzma compressed executable. It recursively scans inside a vendor update, to find a me.bin files for neutering with me_cleaner. This is in preparation for two new ports in Libreboot: * HP EliteBook 8560w * Apple MacBook Air 4,2 (2011) This script can literally be used with multiple vendors now. It is no longer specific just to Lenovo. I originally did this and other recent commits to the file, as one big commit, but I decided to split it all up into small commits.

2023-04-01blobutil/download: move main logic to the topLeah Rowe
Top-down order is easier to read, for greater understanding. What's moved is initialisation. The glue that calls Build_deps and Download_needed still need to be at the bottom.

for example, files being downloaded have nothing to do with the ME; they are merely compressed, and contain many files in addition to it
2023-03-24blobs/inject: use correct offset for haswell mrcLeah Rowe
2023-03-18haswell: re-add mrc.bin in separate board configsLeah Rowe
libre mrc on haswell is quite buggy for now, but works in a limited fashion this patch re-adds the old configs, but as _mrc for example t440p_12mb_mrc instead of t440p_12mb and t440p_12mb (without _mrc) still uses the libre mrc code
2023-03-18haswell boards: use libre mrc.bin replacementLeah Rowe
courtesy of Angel Pons from the coreboot project this uses the following patch set from gerrit, as yet unmerged (in coreboot master) on this date: https://review.coreboot.org/c/coreboot/+/64198/5 logic for downloading mrc blobs has been deleted from lbmk, as this is now completely obsolete (for haswell boards) if other platforms are added later that need mrc.bin, then logic will be re-added again for that
2023-03-05scripts: build cbutils, not specific utilsLeah Rowe
some checks check for specific utils, which are then used to indicate the existence of other utils, which means that building them singularly, as is currently done, may result in errors later if another tool doesn't exist compiled yet this is an obscure bug, fixed by this patch. more of a workaround really. a dirty hack. when checking for any of the coreboot utilities required, build all coreboot utilities that are possibly required the utilities are small enough that this does not add much extra time to build, and in most cases, all of them will be needed anyway

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
