Leah Rowe bd59d01ea2 trees: don't check if xgcc is already built
just run the make crossgcc command anyway.
coreboot's own build system checks itself, and much
more reliably, but the check is more thorough and a bit
slower.

in rare cases, lbmk may come into build issues with xgcc,
and if you run the build again, it will always fail every
time because the checks is based on whether the xgcc
directory exists, rather than checking each
individual crossgcc binary.

checking every binary is also possible, but as i said,
the coreboot build system already does that, so let's defer
to coreboot's own handling of it.

remove the directory check. this will slow down the build
process a little bit, but should improve reliability under
fault conditions.

Leah Rowe e7fcfac14e lib.sh: remove badcmd()
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.

Leah Rowe dec9ae9b43 lib.sh: more unified config handling
replace it with logic that simply uses "." to load
files directly.

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.

Leah Rowe c72904b6d1 trees: more robust check to avoid "make fetch"
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 ./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.

Leah Rowe b50a588cba grub: insert background in memdisk instead
the background is only a few kb. the whole rationale
before was to limit the space used in memdisk, but this
decision was made when the background was much bigger;
it has since been optimised greatly, and the grub modules
were heavily reduce, so it should be safe.

grub's memdisk breaks when you add too much data to it.
as part of simplifying the rest of lbmk, this change removes
some more bloat from the rest of lbmk. handling this in the
memdisk is much simpler than handling it with cbfstool.

i removed this before, when making grub multi-tree,
because the design i used in an earlier version of
the patch actually added the grub.elf generation
to grub source itself, but then i decided to hack

insert their own custom grub.cfg into cbfs without
needing to re-build their image.

don't create elfdir, create dest_dir, which is elfdir
plus the location within it

only create dest_dir within copy_elf, which is only
called if actually compiling the code

this avoids creating empty elf directories, and it
generally cleans up all handling, unifying the
handling of directories into a single function,
namely copy_elf() which already exists

Leah Rowe 591c7d28e0 git.sh: download "depend" projects *before*
don't do it after, because that means the main project
is saved under src/ before we know whether the subrepo
was downloaded.

the "depend" variable (in config/git/) is no longer used
for projects that go in subdirectories of a parent; now,
we use config/submodules/ for this type of dependency.

download the "depend" projects (as per config/git/) first.
this way, if they fail, the main one will fail, but if
they succeed and main fails, you can just run the main
download again and it won't fail.

this fixes a bug where, depending on how you download a
set of projects and depending on the order which you do so,
a given project can become un-downloadable on current design,
because git will complain that a directory already exists.

this fix is done not only in code (by this commit), but
by prior configuration changes.

Leah Rowe 7d99786a1a handle build.list from config/data/, not config/
certain code checks for build.list, to skip it, for
example in items()

we already use config/data/grub to store grub config data
that applied to all trees

create these directories too:

config/data/u-boot
config/data/seabios

to config/data/grub

Leah Rowe eb4ac3c334 make GRUB multi-tree and re-add xhci patches
The xHCI patches were removed because they caused issues
on Sandybridge-based Dell Latitude laptops. See:
https://codeberg.org/libreboot/lbmk/issues/216

The issue was not reported elsewhere, but we still don't
need xHCI support in Canoeboot's GRUB because none of the
available coreboot targets have xHCI support. However, we
may want it in the future and it helps to keep Canoeboot
in sync with Libreboot (this patch is adapted from lbmk).

Each given coreboot target can say which GRUB tree to use
by setting this in target.cfg:

grubtree="xhci"

In the above example, the "xhci" tree would be used. Some
generic GRUB config has been moved to config/data/grub/
and config/grub/ now looks like config/coreboot/ - also,
the grub.cfg file (named "payload" in each tree) is copied
to the GRUB source tree as ".config", then added to GRUB's
memdisk in the same way, as grub.cfg.

Several other design changes had to be made because of this:

* grub.cfg in memdisk no longer automatically jumps to one
  in CBFS, but now shows a menuentry for it if available

* Certain commands in script/trees are disabled for GRUB,
  such as *config make commands.

* gnulib is now defined in config/submodule/grub/, instead
  of config/git/grub - and this mitigates an existing bug
  where downloading gnulib first would make grub no longer
  possible to download in lbmk.

There is another reason for merging this design change from
lbmk, and that reasoning also applies to lbmk. Specifically:

This change will enable per-board GRUB optimisation in the
future. For example, we hardcode what partitions and LVMs
GRUB scans because * is slow on ICH7-based machines, due
to GRUB's design. On other machines, * is reasonably fast,
for automatically enumerating the list of devices for boot.

Use of * (and other wildcards) could enable our GRUB payload
to automatically boot more distros, with minimal fuss. This
can be done at a later date, in subsequent revisions.

i initially moved the nuke function to its own file so as

libreboot will not do full deblobbing like canoeboot does,
but there are still certain files that i like to delete

calling it "nukeblobs" in libreboot makes no sense, but
i like to avoid merge conflicts when cherry-picking
patches between cbmk and lbmk, so i like to make sure
that functions and variables common to both are named
the name.

simply calling it "nuke" or calling the files "nuke.list"
is probably inoffensive while conveying the same meaning.

Leah Rowe 3554593fd8 trees: reset makeargs per target/project
it wasn't being reset before. when coreboot is being
built, i add to makeargs every time. if multiple targets
are being built, the make command would end up looking
something like:

make -C src/coreboot/default UPDATED_SUBMODULES=1 \
    UPDATED_SUBMODULES=1

(the parameter would be printed twice)

of course, this doesn't check whether that parameter is
added already in target.cfg for a given target, but that's
ok because i won't add that one in target.cfg

i baked it into the code, only when handling coreboot,
because that was easier than either putting it in makeargs
for every coreboot target.cfg, or again modifying the code to
handle that; the current solution is the cleanest.

the existing command structure has not changed. for example:

these will still work, but the symlinks to "build" are now
strictly for backwards compatibility; they may be removed
at a later date, but i'll keep the current design for now.

this also leads to a quirk, for example:

./update roms all
