2024-05-29./vendor download: skip if blob path is /dev/nullLeah Rowe
We use a path of /dev/null pointing to a ROM for Fam15h AMD boards, to add fake PIKE2008 images. This is to mitigate a hang in SeaBIOS, but now with recent changes, this causes the command below to download coreboot, when it should just exit saying no vendor files needed. Prevent accidentally wasted bandwidth. The command was: ./vendor download kcma_d8_rdimm_16mb This now correctly does the following: $ ./vendor download kcma_d8_rdimm_16mb Vendor files not needed for: kcma_d8_rdimm_16mb The joys of programming a build system in sh!

2024-05-29./vendor download: more fine-tuned error controlLeah Rowe
By default, the build system does set -u -e Some errors are unavoidable and have to be handled, so we have to set +u +e (turn off error handling in sh), when downloading vendor files, but only certain parts of vendor.sh trigger errors (which cause an exit). Replace the current bazooka approach with a more fine grained approach, turning error handling back on again when it is safe to do so. In the parts of the code where it is disabled, the code is written very, very carefully, with errors still handled manually, but more careful auditing is required. This change has been tested and makes the command much safer to run. In security (or any bug auditing), it is the principle of least privilege that holds true.

2024-05-29vendor.sh: don't error on main targetsLeah Rowe
e.g. coreboot/default contains no config directory, so the old logic would be trying to do: . which is obviously invalid now for example: $ ./vendor download default Vendor files not needed for: default and it will exit with zero status the only thing that should ever return non-zero status is when you define a target that does not exist, config or no.

2024-05-18vendor.sh: move config checks to detect_firmwareLeah Rowe
they will later be removed, as part of unification against other files that perform the same tasks Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-18vendor.sh: print an error upon ill-defined targetLeah Rowe
previously, it was attempting to load the configs and silently failing. we must provide feedback to the user. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-18vendor.sh: remove redundant checkLeah Rowe
we literally do this check twice, in immediate succession. avoid wasted i/o Signed-off-by: Leah Rowe <leah@libreboot.org>

re-use check_defconfig from option.sh Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-16lbmk: allow easier sync with cbmkLeah Rowe
an equivalent change has been made in cbmk. certain lbmk-specific variable names have been made generic, with certain functions and other variables moved around. i maintain sync between libreboot and canoeboot, where both projects can have the same behaviours, and most of the merge conflicts have to do with variable names containing "LBMK", "lbmk", "cbmk" or "CBMK", or indeed "canoeboot" and "libreboot" LBMK/lbmk/CBMK/cbmk variables between canoeboot and libreboot now contain the string XBMK/xbmk it should now be *much* easier to merge build system changes between lbmk and cbmk.

2024-05-11remove haswell mrc blob (libre raminit stable now)Leah Rowe
broadwell mrc is retained, because it's needed on 820 g2 it's no longer needed on haswell, because nri is stable. nri is short for "native ram initialisation", and libreboot provides this for: thinkpad t440p, thinkpad w541, dell optiplex 9020 mt, and dell optiplex 9020 sff remove, in line with libreboot's binary blob reduction policy previous revisions, prior to the recent release, stated that it would be retained for compatibility, but it's really not right to retain it, because doing so violates libreboot's policy the recent release excluded mrc-based rom images for haswell machines, providing only those rom images that use the libre raminit, while retaining support for mrc in the build system, so that users could still run the lbmk inject script on older release roms that use mrc again: libreboot's binary blob reduction policy is very clear: https://libreboot.org/news/policy.html it is a policy that can be summarised, thus: if a blob can be avoided, it must be avoided. therefore, we will avoid the Haswell MRC raminit blob Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-11merge script/vendor/* into include/vendor.shLeah Rowe

2023-10-15delete include/vendor.sh and merge elsewhereLeah Rowe
move it all to other files where items are used, and not used anywhere else. this reduces the size of vendor.sh. also remove a few redundant variables, or variables that are not meaningfully used. a few items have been moved to include/option.sh Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-15vendor.sh: move some functions to vendor/downloadLeah Rowe
they are the functions only used by the download script, so they don't belong in vendor.sh an include file should only contain variables and functions used by multiple main scripts Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-10-14update/release: nuke roms using the inject scriptLeah Rowe
This way, the handling of configs is unified into one script, which reduces the possibility of bugs later, and it reduces the repetition of code. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-12use me_cleaner from coreboot instead of upstreamLeah Rowe
coreboot closely matches upstream, whose current release is version 1.2 from 2018, and coreboot has not changed it in any meaningful way. the upstream did add patches since, but they are documentation patches only. this means: we do not need to use the upstream version Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-07rename blob/ to vendor/Leah Rowe
in the future, we may start downloading files that aren't blobs, such as mxm port configs (on mainboards that use MXM graphics) this directory will contain all of those files generally change the language used, across lbmk, to make use of "vendorfile" instead of "blob" Signed-off-by: Leah Rowe <leah@libreboot.org>
