2023-09-30build/boot/roms: only do 1 custom kbd/payload/modeLeah Rowe
-k, -p and -d let you set keymap, payload and displaymode respectively, but the handling for this is buggy when passing multiple arguments. Support only one argument, for simplicity. This is how people use them anyway, and it makes lbmk less buggy. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-30build/boot/*: unified main() functionLeah Rowe
The *same* main() function is now used on both scripts. However, merging both scripts together would be less efficient on sloccount, and would be error-prone. The purpose of having roms_helper is that the variables get re-initialised the same way each time, for each board, automatically. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-25Update email address for Leah Rowe copyrightsLeah Rowe
also, some of them were out of date; years now updated. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-25Use SPDX license headers on all scriptsLeah Rowe
This results in much cleaner copyright and license declarations. SPDX headers are legally recognised and make auditing easier. Also, remove descriptions of each script, from each script. Libreboot documentation at docs/maintain/ describes them. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-10build/boot/roms stragglers: properly handle errorsLeah Rowe
there were a few missing err calls i actually went through all of lbmk and found no instances where err calls were missing except in build/boot/roms_helper Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-09scripts: use printf, not echo, where appropriateLeah Rowe
printf has more universal behaviour, across various implementations of sh, so it's better to use this. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-09build/boot/rom: only insert scan.cfg if neededLeah Rowe
where it is set to "both" (grub_scan_disk), inserting scan.cfg is superfluous, because grub.cfg defaults to both anyway, unless otherwise specified by scan.cfg, and only if that file exists within cbfs. thus, save a bit of build time (only a slight saving) Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-09-09set grub.cfg timeout to 5s (10 on some boards)Leah Rowe
target.cfg can now specify e.g. grub_timeout=20 this would then be inserted as timeout.cfg in cbfs, containing the instruction: set timeout=20 HP laptops need a bit of extra time, due to the delay caused by the EC bug workaround deployed in GRUB desktops in general need extra time. this too is set to 10s, like the HP laptops. only insert timeout.cfg if actually needed (declared in target.cfg), otherwise grub.cfg will default to 5s Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-05grub: make backgrounds configurable in target.cfgLeah Rowe
now under coreboot mainboards, target.cfg can specify a background. if not specified, the 1280x800 one is assumed, and used by default. it can be overridden. the path should be relative to: config/grub/background/ Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-09-04build/boot/roms: don't create empty bin/ directoryLeah Rowe
also: only return zero status if rom images were succesfully built, and print a list of each rom image directory based on what was actually compiled, rather than just saying that the rom images are stored under bin/ Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-09-03Less cat abuseRiku Viitanen
More than 90% of cats were thus terminated. read (shell built-in) is better at reading, and dogs are better pets. Signed-off-by: Riku Viitanen <riku.viitanen@protonmail.com>
2023-08-31only remove microcode in build/release/romsLeah Rowe
libreboot's build system, lbmk, *is* available to use in releases aswell (use the _src tarball), but it is mostly intended for development, in lbmk.git well, there's not much point wasting time / disk space generating no-microcode roms within lbmk they should be generated only at release time, alongside the default ones this patch implements that, thus speeding up the build process and saving disk usage during development the other alternative was to add a new option in build/boot/roms, -m, that would opt in to removing them, but this is extra complexity for something that is ill advised and only provided to appease certain people Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-08-31move build/boot/rom moverom to handle/make/configLeah Rowe
most of these steps do not need to be repeated, per image. move it into handle/make/config, so that the steps are performed on files that go under elf/coreboot (this will save on build time). the logic for handling 4MB ROM images on sandy/ivy was unused, and has been removed.

2023-08-29grub: all one grub.elf containing keymaps and cfgLeah Rowe
new behaviour: * grub.cfg and grubtest.cfg no longer inserted to cbfs * grub.cfg in memdisk instead * grub.cfg in memdisk defers to cbfs/grub.cfg if added (not added by default, anymore) * does not defer to grubtest.cfg even if available * only shows link to grubtest.cfg if available, as a menuentry item keymaps: if /keymap.gkb exists in cbfs, it uses that by default, but by default this isn't added. instead, it looks for a file named keymap.cfg and sources that, which then sets the keymap to one that is located under memdisk. this file is inserted for each rom, per layout. if keymap.gkb and keymap.cfg both absent, grub.cfg in memdisk shall defer to usqwerty as the default keymap grub_scan_disk: grub.cfg looks for cbfs file "scan.cfg" and sources that if found, which will be inserted with the string: set grub_scandisk=setting_goes_here (based on target.cfg, generated by build/boot/roms automatically). If no scan.cfg is found, it defaults to "both" The "background.png" file remains unchanged, and present in CBFS, used by grub.cfg if present (and it is, by default) This change actually *saves* space in CBFS, due to compression, and means that the grub.cfg is now compressed heavily. This is also safer, because now the user overrides grub.cfg by adding it, and they can still add grubtest.cfg for testing first. If they accidentally delete both configs from cbfs, Libreboot will fall back to the one in memdisk which would presumably not be deleted. This also means that lbmk can now more easily be used by other build systems, that just want the GRUB part to re-use in their own project. For example, people who want to build custom coreboot images without using Libreboot's build system. This change also *speeds* up the build process considerably, on the parts where ROM images are copied. It's less than half a second now, whereas previously it took about 30-45 seconds for ROM images to copy, because of grub.elf being re-added in each ROM via cbfstool, where compression is used; I believe the compression part is what caused slowness. Much, much faster, more versatile builds. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-08-28build/boot/roms: fix bad variable assignmentLeah Rowe
this was an oversight, in a previous commit. there was a space, between variable name and the equals sign, and then another space, so it was trying to *execute* the rom Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-08-28build/boot/roms: use the new coding styleLeah Rowe
lbmk's new style is inspired by the bsd coding styles: top-down logic, main simplified to a skeleton showing overall program structure, variables well-defined, rigorous (yet deceptively simple) error checking. this was attempted before, but caused problems; coreboot wasn't being cleaned properly, and rather than audit it, i simply reverted this back to the old style. this is actually attempt number 5, because i made 3 more attempts between then and this one. i've build-tested this using "./build boot roms all" (which is what b0rked on the first attempt, months ago). it should be stable(tm). the code is much nicer to read / work on now. this is the beating heart of lbmk. get this script wrong, and you break all of libreboot.
