2023-12-27update/trees: further simplify crossgcc handlingLeah Rowe
arch no longer needs to be set, on multi-tree projects, and it has been renamed to xarch the new behaviour is: if xarch is set, treat it as a list of crossgcc targets and go through the list. set the first one as the target, for what lbmk builds, but build all of the defined crossgccc targets crossgcc_ada is now xlang, and defines which languages to build, rather than whether to build gcc-gnat Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-24lbmk scripts: shorter code linesLeah Rowe
while seemingly pedantic, this does actually make code easier to read. mostly just switching to shorthand for variable names, where no expansions or patterns are used Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-12-23build/roms: improved error handling for romsLeah Rowe
the rom functions print a path to the rom they built, which is then used, but these are called inside what are essentially subshells, and we had no error handling Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-23build/roms: remove redundant checkLeah Rowe
cros roms are always using libgfxinit, with a coreboot framebuffer, so the "normal" initmode is never used. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-23set version/projectname properlyLeah Rowe
lbmk used to set version/versiondate directly in err.sh, but now it's handled there by a function, which is called by the main script. script/update/release hadn't yet been adapted. the only change necessary is to call check_project() script/update/trees also makes use of it script/build/roms is using "projectname" Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-23don't delete microcode updates in rom imagesLeah Rowe
at present, lbmk can remove microcode updates on images for a given target, if the target specifies microcode_required="n" in target.cfg lbmk then provides images with microcode, and images without, in a given release. although the user can also remove them manually, this just makes it a bit more convenient, for those users who do wish to run without the updates. this functionality is provided only on those platforms where no-microcode is tested. well, this behaviour implements a compromise on libreboot policy, which is to always include microcode updates by default. see: Binary Blob Reduction Policy the *canoeboot* project now exists, developed in parallel with libreboot, and it ships without microcode updates, on the same targets where lbmk also handled this. running without microcode updates is foolish, and should not be encouraged. clean up lbmk by not providing this kludge. the libreboot documentation will be updated, telling such users to try canoeboot instead, or to remove the update from a given libreboot rom - this is still possible, and mitigations such as PECI disablement on GM45 are still in place (and will be kept), so that this continues to work well.

2023-12-21build/roms: remove modify_coreboot_rom()Leah Rowe
don't handle "romtype" at all, in board target.cfg files add /dev/null as pike2008 rom on amd boards. this serves the same purpose, adding them as empty vga roms, to add an empty rom in cbfs. pike2008 cards cause seabios to hang, when their oproms are executed, so we insert a fake rom on i945 thinkpads, use the coreboot config option: CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK when set, this enables the same bootblock copy, for use with bucts. these two cases, namely pike2008 roms and i945 bootblock copies, no longer need to be handled in code Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-16remove DEBUG handling in lbmk (not needed)Leah Rowe
all it did was set -v in the shell, which doesn't yield very useful results. this is a relic of very old design in the libreboot build system, that is no longer needed. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-16fix several shellcheck warningsLeah Rowe
lbmk didn't quote certain arguments in commands, or used ! -z instead of -n, things like that. simple fixes. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-11-08lbmk: don't use status for unconditional returnsLeah Rowe
in cases where lbmk must always return from a function, there are some cases where it relies on non-zero exit status, which in practise is always the case, but may change in the future if the relevant part is modified e.g. do_something && return 0 the proper form is: do_something return 0 also do this for unconditional exits Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-11-01build/roms: re-add SeaGRUB build supportLeah Rowe
it didn't work in the past, but it does work nowadays; specifically, it only worked with libgfxinit in the past, but not on VGA ROMs. now it does work on VGA ROMs, tested on e6400 and t1650 so it was enabled there. in this setup, a special image is provided where SeaBIOS is the main payload, but it only loads GRUB; nothing else, every. this is called SeaGRUB. this setup is useful in cases where the user only has a GPU that lacks libgfxinit support.

2023-10-31build/roms: properly print noblobs rom namesLeah Rowe
when printing the name of the rom being created, it's done before the check to rename based on vendorfiles in target.cfg. this patch fixes that bug. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-25include/option.sh: fix i945 bootblock copyLeah Rowe
it wasn't being copied right the roms under elf/ were being copied, but not the ones under bin/ - i need to audit it further for now, i run modify_coreboot_roms from build/roms instead of update/trees so, the ones under elf/ no longer have bootblocks copied. it's only done in bin/ Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-24build/roms: copy base rom again for u-bootLeah Rowe
when building only for u-boot, the current script works just fine. however, when building for other payloads in additional to u-boot, the final u-boot stage fails because other payloads are already inserted via cbfs. when we build u-boot, we do that last because we want u-boot setups to only be u-boot, nothing else. this patch enables qemu x86 to build properly with u-boot.

2023-10-2220231021hotfix: replace x_ with err in some places20231021fixLeah Rowe
keymaps weren't being set in keymay.cfg of cbfs, due to use of x_ in the rom script, and x_ doesn't handle quotes or spaces in arguments well. i'm going to remove use of x_ and xx_ (it's in my todo), for next release. for now, hot patch the release. i've gone through and replaced use of x_ with || err, in some places. not just the keymap.cfg command, but others too. in case there are more issues we missed. this commit is being tagged "20231021fix" and i'm using this tag to re-build the 20231021 release. i'll just replace the tarballs in rsync and add errata to the news page announcing the release. all i did was break peoples umlauts, i didn't brick their machines fortunately! very minor bug. anyway, x_/xx_ is a great idea, but sh isn't really designed for that style of programming. i'll go back to using just || err in the next release.

2023-10-20lbmk: use 2-level directory structure in script/Leah Rowe
as opposed to the current 3-level structure. recent build system simplifications have enabled this change, thus: ./build fw coreboot -> ./build roms ./build fw grub -> ./build grub ./build fw serprog -> ./build serprog ./update project release -> ./update release ./update project trees -> ./update trees ./update vendor download -> ./vendor download ./update vendor inject -> ./vendor inject alper criticised that the commands were too long, so i made them shorter!
