in practise, it was always correct because on projects
that used coreboot xgcc, the tree would always be called
default.
however, this is a bug. the logic uses a correct directory
name for coreboot in src/, but not elf/
this patch makes the two consistent, programattically.
this is therefore a preventative bugfix.

libreboot's policy is to thoroughly clean sources per
build, because we cache builds out of tree and avoid
re-builds if they exist; these and the sources are
deleted if metadata in config/ changes per project,
tree and/or target.
the problem is that this change only affects lbmk.git
it doesn't affect release archives, where project sources
do not have git-init applied to them. this will be
addressed.
can't use it on coreboot, because it will delete xgcc
tarballs in a way currently not handled, and handling
it will mean adding a project-specific hack.
the xgcc tarballs could be built out-of-tree, and this
will have to be done, otherwise coreboot will have to be
made gitclean="y" for now.
everything else is fair game.

yes, make it generalised. use a new variable in
mkhelper.cfg, gitclean and gitcleanargs
not enabled by default, but u-boot enables it. i'm
considering whether to use this by default, as it
is the general policy of lbmk to clean everything
just after a build, as builds are cached out of
tree. this way, we can do re-builds safely for each
project. there are probably a lot of subtle bugs that
might be fixed if we used this
the problem is that this is currently only used on
lbmk.git, but not on libreboot release archives which
lack .git directories; the main one is initialised in
lbmk, but not in upstream sources. we could just initialise
those.
in fact, that is probably what i'm going to do.

totally useless function. all it does is print
quotes. just printf the args into awk
this does literally the same thing. the output
will literally be the same.

do it from mk instead. we don't need to run pwd
anymore, because we just get the path and cd
to it, setting that as the path.

it should be clear on first reading, what the actual
control flow is. hiding the call in init.sh obscures
first reading.
now it is absolutely clear on first reading, that
xbmk_init is called before going through everything

util/crossgcc: Fix GNAT detection for gnat-15
this one is advisory instead, telling the user to
create such a symlink as we did. this is much less
invasive.
our own check was bad, because it basically silences
what is otherwise an error. coreboot's approach is
more correct, so we will defer to that instead.
note that this means older coreboot (for fam15h) is
no longer covered, but those trees don't use gnat
anyway as libgfxinit is unused on those targets
this lbmk patch removes 61 sloc of dead code, which
makes me very happy.

mk is so tiny now, and will likely never get
bigger. tree.sh is effectively the main script
now, so let's treat it as such.
i'll start splitting tree.sh instead. e.g.
move gcc setup to its own file.

this solves a bug that does not yet manifest, because
this bug *can't* currently trigger any error due to
lbmk's design. this is therefore a preventative fix,
for reasons that will become clear.
we previously put arguments in a variable, in a way
that didn't handle globbing. now we avoid a variable
and use "$@" instead, which solves the problem.
this also means that the main logic in mk can be
cleaner, as trees-specific control logic is now
placed entirely in tree.sh's main.
this means that we can now also wrap x_ around trees()
this was never a problem in the past, because all of
the arguments for trees commands never have globbing;
config names are always e.g. foo_bar, not foo bar
in commands where globbing did need to be handled,
those commands were never trees commands. e.g.
you had ./mk inject filename
yes, this is a design improvement, or a preventative
bug fix. pick your poison.

the previous design flaw was fixed by recent
refactors, such that i can now . include all
of lbmk at once, and have control logic right
after that.

just do includes in mk again. common.sh was stupidly
small, just pointless.
replace the entire command dispatcher with eval, printf
and awk, because i can, and it further reduces sloccount.

not needed at the moment, since we ensure that
the functions always exit with error under fault
condition. they always return zero.
nevertheless, this might catch some unexpected

we don't need a main here. it's so generic that we
can just leave it really small like it is now. now
it's much clearer what it actually does.

commands now fed from a file, include/common.sh
which in turn also includes other lib files
this makes mk completely generic, and means
that changes will now be completely in sync
with cbmk, ensuring a lack of merge conflicts,
though the file was already pretty small anyway.

now you can put lbmk somewhere on your system,
and symlink to the mk script from PATH
e.g. /usr/local/bin/lbmk -> /home/leah/lbmk/mk
lbmk will cd to itself, including from PATH,
because the string will then be passed through
readlink, which gets the real path.

i need only now implement a check for sys dirs
e.g. /etc/lbmk.cfg and check if it defines
e.g. other location for config/ and include/
then mk is a generic dispatcher and i can one
day make mk possible to install. for example, if
you have a bsd ports system and you want to
install lbmk
i could make it check user dirs too, overriding
defaults. for example /usr/local/etc/lbmk, but
then i might have ~/.config/lbmk
you no longer need to be in the xbmk directory
to run xbmk. it'll cd to itself, with this patch

with this new function, i can turn commands on and

I intend to merge every Chromebook that Mrchromebox supports,
into Libreboot, ready for the Libreboot 25.12 release. Work
is still ongoing, and several changes need to happen in lbmk.
I started working on it a few weeks ago (today is
14 November 2025 as I push this).
Still TODO:
* Automatically create lbmk coreboot targets, based
on the configs present in MrChromebox git
* Re-work git repository management in lbmk, such that
a list of upstreams is used, instead of a hardcoded
list per configuration; this will allow us to use
different remotes across the same project, even where
they diverge. This would then allow us to use the
MrChromebook repository directly, instead of cherry-picking
patches into upstream coreboot
* The note above about remotes would also mean that we can
use MrChromebox's own edk2 repository directly. All of this
would reduce the burden on lbmk.git
* Support building edk2 payloads, exactly mirroring the
setups used on MrChromebox builds
There are some things that need to be checked first, for
boards that use MMC-based or eMMC-based storage, for the
GRUB and SeaBIOS payloads, also U-Boot, because I will
also be using these.
As such, this current script shall sit in lbmk master, but
it is not yet finished.
