2024-06-22roms: remove support for "grubonly" seabiosLeah Rowe
due to lbmk issue #216, it is now unwise to use grub as the primary payload on any machine; the sheer complexity of grub and the number of memory corruption bugs that have been fixed due to auditing over the years, means more such bugs exist. we now provide seabios as the primary payload on all x86 ports, but provide a "grubfirst" configuration where a bootorder file in seabios can be added via cbfs, which tells seabios to load grub from cbfs first, while still allowing use of the boot select menu by pressing esc in seabios. well, the "grubonly" option also disables the seabios esc menu, so that *only* grub runs. there is no point in using this unless you want to harden your setup, for example if you want to set up encrypted /boot and boot that from grub, and have a grub password disallowing unauthorised bootup of your machine. see grub hardening guide; https://libreboot.org/docs/linux/grub_hardening.html at least as of today, 22 June 2024, that page already says how to manually disable the seabios menu in the same way, if that is the setup you want. alternatively, a user may be wily enough to edit target.cfg for their board and compile a rom that only has the grub payload in it, if that is what the user wishes to do. regardless, the default configurations provided by lbmk must never be unsafe, norc should the build system support such unsafe settings; yes, grub as primary payload is technically still supported in lbmk. actually, at the time of this revision, i have half a mind to remove that functionality altogether, so that only seabios is allowed as primary payload, when compiling a rom image that also has grub, chainloading grub from the seabios menu instead.

2024-06-22lib.sh: remove badcmd()Leah Rowe
it's bloat. telling the user to rtfm is something that we already do on irc; they will still ask how to do everything, and ignore the message from badcmd(), or they will automatically know to rtfm. i'm on a massive purge, removing bloat from lbmk as part of Libreboot Build System Audit 6. all bloat must go.

2024-06-22lib.sh: more unified config handlingLeah Rowe
replace it with logic that simply uses "." to load files directly. for this, "vcfg" is added as a variable in coreboot target.cfg files, referring to a directory in config/vendor/ containing a file named pkg.cfg, and this file then contains the same variables as the erstwhile config/vendor/sources config/git files are now directories, also containing pkg.cfg files each with the same variables as before, such as repository link and commit hash this change results in a noticeable reduction in code complexity within the build system. unified reading of config files: new function setcfg() added to lib.sh setcfg checks if a config exists. if a 2nd argument is passed, it is used as a return value for eval, otherwise a string calling err is passed. setcfg output is passed through eval, to set strings based on config; eval must be used, so that the variables are set within the same scope, otherwise they'd be set within setcfg which could lead to some whacky results. there's still a bit more more to do, but this single change results in a substantial reduction in code complexity.

2024-06-21trees: more robust check to avoid "make fetch"Leah Rowe
do not use shorthand here. the test was failing to produce the desired result under some circumstances, for example when i did "./update release" i got this: make: Entering directory '/home/lbdev/lbmk/release/20240612-62-ga6b1a6bd/libreboot-20240612-62-ga6b1a6bd_src/src/stm32-vserprog' make: *** No rule to make target 'fetch'. Stop. make: Leaving directory '/home/lbdev/lbmk/release/20240612-62-ga6b1a6bd/libreboot-20240612-62-ga6b1a6bd_src/src/stm32-vserprog' ERROR script/trees: !mk src/stm32-vserprog fetch ERROR ./update: excmd: script/trees -f ERROR script/roms: Unhandled non-zero exit: ./update ERROR ./build: excmd: script/roms serprog ERROR ./update: build_release release/20240612-62-ga6b1a6bd: stm32 ERROR ./update: can't build rom images in the above circumstance, run_make_command was executed, which is not the desired behaviour; rather, fetch_project_trees or fetch_project_repo should be called, and then the script should immediately exit. it should also exit, without downloading anything, if a changelog file exists as in release archives.

2024-06-20Revert "roms: remove build_payloads() and split it up"Leah Rowe
This reverts commit 3610667e3db08ff1db4f7784ff5a879d8aebce9d. The output of some functions in the roms script are used as an argument in cp and mv commands, also cbfstool. I overlooked this fact in a previous code optimisation. Revert it. The change only reduced sloccount by a few lines anyway.

this is bloat, because it's something the user can already do at runtime configuration anyway. set it to a reasonable default of 8 seconds instead of 5, and don't honour the timeout variable in target.cfg. this will be documented in the next release. Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-06-19roms: remove build_payloads() and split it upLeah Rowe
payloads are compiled before coreboot, but it doesn't matter to the build speed whether this is done first. reduce the lines of code by checking payload builds *while* adding them to the coreboot images. this means that coreboot is now compiled first, before the payloads.

2024-06-17roms: remind the user about gkb filesLeah Rowe
nowadays, we don't insert GRUB keymaps automatically, for sake of efficiency; without one, the default is US QWERTY. a user will only want one keymap in particular, so this is more efficient. in practise, they're either building from source anyway, or using the inject scripts which compile cbfstool anyway, so the user will already have cbfstool. also output this message from the inject script.

2024-06-17roms: rename x variable to it in for loopaudit6-merge1Leah Rowe
there are two for loops that use x as a variable anme, and an idiosyncrasy of certain sh implementations is that these become global; the result in this case was that when you finish building every target in "./build roms", it would print "libgfxinit" repeatedly, comma separated, instead of a comma-separated list of the targets that were built. work around it by renaming the variable in one of the loops.
