12 daysNEW MAINBOARD: ThinkPad T480Leah Rowe
This uses the excellent deguard utility, written by the excellent Mate Kukri. A few bugs but it mostly works. Documentation to come shortly, in lbwww.git. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-11-07clean up the coreboot submodulesLeah Rowe
also bring the coreboot/next modules in line with the recent merge that did away with coreboot/dell7 the submodules for coreboot/haswell were still there, and have now been deleted; the haswell tree was used for the NRI patches, which were moved to /default some time ago Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-11-04coreboot/default: remove unnecessary moduleLeah Rowe
The fsp module is unnecessary on coreboot/default, and therefore constitutes a waste of disk space. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-10-27Switch Dell 3050 Micro to newer coreboot revisionLeah Rowe
Specifically, use the same revision that Mate used in patchset 15. This will ensure that any issues are *not* caused by the coreboot revision; this is being done, because the old coreboot revision was from July, but patchset 15 from Mate is based on a September revision of coreboot. I've been eliminating as many variables as possible, trying to fix SeaBIOS payload on this machine, because it hangs in Libreboot, but not when building from gerrit directly, which means the coreboot revision may be a factor (since I'm using his patches on an older revision so upstream might have made some changes since then that the port relies on). For this, a new coreboot tree is used, called "dell7", referring to the fact that Kabylake is Intel's 7th generation. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-10-05Add config for Dell OptiPlex 3050 MicroLeah Rowe
This is using Mate Kukri's port, which was added in previous lbmk revisions. I've added an IFD that sets the HAP bit, and unlocks regions as standard. vcfg is set to 3050micro, which defines downloading of the MEv11 image and it will run deguard automatically. I made a small adjustment to vendor.sh, because the hotpatch logic for deguard uses -C in git, and when doing that, the specified directory path is relative to that Git repository; the .patch path has been adjusted accordingly. Also add 3rdparty/fsp to coreboot/default modules. This board requires the ifdtool option: -p sklkbl The -p option tells flashrom what quirks are present in a given IFD. We don't normally need this on other Libreboot targets that we currently support. The -p option was needed for creating this modified IFD, and it is therefore needed in the inject script. Therefore, an "IFD_platform" option is specified in a given board's target.cfg file. If this is set, another variable is set that makes -p be used. In this case, 3050's target.cfg says: IFD_platform="sklkbl" This option enables quirks for skylake/kabylake descriptors, as required when using ifdtool. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-08-10coreboot/fam15h: only use this, for amd boardsLeah Rowe
it is identical to fam15h_rdimm, with _udimm now removed; the latter had a patch that added certain behaviour only intended for rdimm, but the patch in question breaks various configurations. raminit has always been unreliable on these boards. i'd rather simplify it all, in lbmk. i'll probably update this to the dasharo tree later on, specificalyl for kgpe-d16 Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-08-09coreboot/dell: merge into coreboot/defaultLeah Rowe
The libgfxinit patch and other patches e.g. DDR2 fix, are now provided in coreboot/default. The Latitude E6400 is now using the newer coreboot revision from late July 2024. Some other configs had to change because of this, relating to the new way that Nicholas handles timing on LVDS displays with the E6400 port; a default 96MHz clock is still used for pixel reference clock, overridden with a value of 100MHz on other GM45 machines, where 96MHz was previously hardcoded.

2024-08-09coreboot/default: Update to 97bc693ab (2024-07-29)Leah Rowe
Several patches are now merged upstream and no longer needed in lbmk, such as the HP EliteBook 8560w patch, and related patches. Some patches were changed, for example the Dell Latitude ivb/snb laptops are now variants in coreboot, instead of being individual ports; now they re-use the same base code. This this, the corresponding files under config/submodules have changed, for things like 3rdparty submodules e.g. libgfxinit, and tarballs e.g. crossgcc. This is long overdue, and will enable more boards to be added. This newer revision will be used in the next release, and some follow-up patches will merge these trees into default: * coreboot/haswell * coreboot/dell Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-12coreboot nasm: use coreboot mirror as backupLeah Rowe

2024-06-08git.sh: support downloading *files* as submodulesLeah Rowe
when we download coreboot, we currently don't have a way to download crossgcc tarballs, so we rely on coreboot to do it, which means running the coreboot build system to do it; which means we don't get them in release archives, unless we add very hacky logic (which did exist and was removed). the problem with coreboot's build system is that it does not define backup links for each given tarball, instead relying on gnu.org exclusively, which seems OK at first because the gnu.org links actually return an HTTP 302 response leading to a random mirror, HOWEVER: the gnu.org 302 redirect often fails, and the download fails, causing an error. a mitigation for this has been to patch the coreboot build system to download directly from a single mirror that is reliable (in our case mirrorservice.org). while this mitigation mostly works, it's not redundant; the kent mirror is occasionally down too, and again we still have the problem of not being able to cleanly provide crossgcc tarballs inside release archives. do it in config/submodules, like so: module.list shall say the relative path of a given file, once downloaded, relative to the given source tree. module.cfg shall be re-used, in the same way as for git submodules, but: subfile="url" subfile_bkup="backup url" do this, instead of: subrepo="url" subrepo_bkup="backup url" example entries in module.list: util/crossgcc/tarballs/binutils-2.41.tar.xz util/crossgcc/tarballs/gcc-13.2.0.tar.xz util/crossgcc/tarballs/gmp-6.3.0.tar.xz util/crossgcc/tarballs/mpc-1.3.1.tar.gz util/crossgcc/tarballs/mpfr-4.2.1.tar.xz util/crossgcc/tarballs/nasm-2.16.01.tar.bz2 util/crossgcc/tarballs/R06_28_23.tar.gz the "subrev" variable (in module.cfg) has been renamed to "subhash", so that this makes sense, and that name is common to both subfile/subrepo. the download logic from the vendor scripts has been re-used for this purpose, and it verifies files using sha512sum. therefore: when specifying subrepo(git submodule), subhash will still be a sha1 checksum, but: when specifying subfile(file, e.g. tarball), subhash will be a sha512 checksum the logic for both (subrepo and subfile) is unified, and has this rule: subrepo* and subfile* must never *both* be declared. the actual configuration of coreboot crossgcc tarballs will be done in a follow-up commit. this commit simply modifies the code to accomodate this. over time, this feature could be used for many other files within source trees, and could perhaps be expanded to allow extracting source tarballs in leiu of git repositories, but the latter is not yet required and thus not implemented.

2024-05-24config: add backup coreboot submodule repositoriesLeah Rowe
this is using the same functionality that was added a few commits ago, to override the use of "git submodule update" each coreboot submodule has two repositories defined, with the second one kicking in if the mail one fails upon cloning. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-05-21Fix E6400 display reference clock patchesNicholas Chin

2024-05-21fix building coreboot images on i686 hostsLeah Rowe
firstly, memtest86+ is currently not cross compiled and relies on 64-bit headers (x86_64 only). a 32-bit distro is unlikely to be able to build 64-bit binaries. secondly: vboot throws a build error due to -Werror when building on 32-bit hosts. we rely on vboot code to build cbfstool, so turn off -Werror on vboot that's all. 32-bit hosts are not recommended; it is assumed that you are building on an x86_64 host. work will go into the build system at a later date to make it more portable, by cross compiling everything, but this should fix 32-bit for now. there are some x60/t60 users who still want to build roms, so let's allow them that possibility.

2024-05-20Fix E6400 display issue with 1440 x 900 panelNicholas Chin
The E6400 uses a 100 MHz reference clock on DPLL_REF_SSCLK, whereas libgfxinit assumed that the reference was always 96 MHz. The frequency difference caused by a 100 MHz reference with PLL config values calculated assuming a 96 MHz reference were not significant enough to cause noticable issues with the more common 1280 x 800 panels, but are enough to matter for the 1440 x 900 panels which use a higher pixel clock. This only affected the pre-OS graphics environment provided by libgfxinit, as Linux drivers would determine the reference clock frequency based on data in the VBT. Fix this by making the reference clock frequency in libgfxinit configurable for GM45 based on a new coreboot Kconfig, which is set to 100 MHz for the E6400.

2024-05-20git.sh: allow patching submodulesLeah Rowe
for single-tree project (e.g. flashprog): config/submodule/PROJECT/MODNAME/patches for multi-tree project (e.g. coreboot): config/submodule/PROJECT/TREE/MODNAME/patches MODNAME is e.g.: 3rdparty/vboot directory in coreboot: would become vboot (the submodule codepath is filtered to up to the final slash) another example: submodire src dir 3rdparty/foo/bar MODNAME would be "bar" Add whatever patches you like to a given submodule. An example patch is included in this commit. Signed-off-by: Leah Rowe <leah@libreboot.org>
