2023-08-22.gitignore: ignore *all* seen filesLeah Rowe
u-boot and seabios are now handled by the same logic as coreboot, in lbmk, and these files are used for recursive downloads in the build system Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-08-19consolidate u-boot/seabios/coreboot build scriptsLeah Rowe
See file: resources/scripts/build/defconfig/for It is based on: resources/scripts/build/payload/u-boot The u-boot payload script has been deleted, as has the seabios payload script; the build/boot/roms logic has been heavily simplified too, by removing the logic for building of elf files based on defconfig. SeaBIOS, U-Boot and coreboot all use defconfig-type infrastructure for their build systems, and they are fundamentally the *same* in how to compile each codebase, at least in an lbmk context, regardless of actual (and very huge) differences in these codebases. Several hundred sources-lines of code have been eliminated by this change, drastically simplifying everything; U-Boot payload compiling also now errors out when a single build fails, instead of continuing. Also: build/boot/roms no longer re-compiles a coreboot target that was already compiled, which is the same behaviour observed for payloads. (this means you must now manually delete a target, when you wish to re-build it; the build/boot/roms logic now more or less just runs cbfstool; blobutil is handled from build/defconfig/for) ALSO: Since crossgcc is now handled by build/defconfig/for, not build/boot/roms, standalone compiling of u-boot is now possible. This has been tested. You compile it like so: ./build defconfig for u-boot or specific trees, e.g. ./build defconfig for u-boot default One other consequence of this patch is that re-building the same ROM image is now much faster, because the same builds are re-used unless deleted. This could be useful when testing grub.cfg changes, for example, if that's all you change. With things like ccache used (not yet used robustly in lbmk), this could speed things up more, depending on the codebase. This patch demonstrates the raw power of lbmk; it is a very simple and highly efficient build system, and now much more so! Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-08-14NEW BOARD: Dell Precision T1650Leah Rowe
Very nice ivybridge board that supports ECC RAM. NOTE: I couldn't get onboard graphics working yet, but this was confirmed working with a graphics card (in my case nvidia quadra k420) booted in text mode on the SeaBIOS payload. The GRUB payload also works, when loaded from SeaBIOS. Therefore, this is a SeaBIOS-only board (as far as first payload is concerned), but you can pick GRUB from the menu. You could make it "GRUB-only" in practise by setting SeaBIOS boot order to only load GRUB, and disable the SeaBIOS menu. We refer to this as "SeaGRUB". I've made lbmk use biosutilities and uefiextract, to get at the SMSC SCH5545 Environmental Control (EC) firmware. This firmware is needed for fan control. This is automatically downloaded and extracted, from Dell UEFI firmware updates. As with other blobs such as Intel ME, this firmware is then scrubbed by the release build scripts. The blobutil "inject" script can be used to re-insert it. Of note: there is no fixed offset, but no other blobs to be inserted in CBFS either, so the offset when re-inserting on release ROMs should still be the same, and thus the ROM checksums should match, when running blobutil inject.

2023-06-17Cache downloads based on checksumRiku Viitanen
Since many boards use the same ME firmware, we could save everyone's bandwidth and time by caching the update files. Signed-off-by: Riku Viitanen <riku.viitanen@protonmail.com>

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
2023-04-08add ich9utils back to utilsLeah Rowe
don't download it. keep it in lbmk. libreboot moved to codeberg for git hosting, and i didn't want to keep lugging around an extra git repo just for one tiny project.

2021-12-29Fix grub's slow bootVitali64
On many boards, grub takes a very long time to search for a grub.cfg file on the disk. The problem is the search_grub function which takes a long time to complete. I (vitali64) studied the grub.cfg from 2016 and the grub.cfg from 2021 and optimized the grub.cfg. It should be faster now.
2021-11-22update coreboot and nuke tianocore20211122Leah Rowe
tianocore is a liability for the libreboot project. it's a bloated mess, and unreliable, broken on many boards, and basically impossible to audit. i don't trust tianocore, so i'm removing it.
