"./update project trees" is a leftover from the
old build system design, prior to audits.
this particular call is for when xtree is defined,
which means that a given tree must rely on the given
coreboot tree defined by xtree. the "xtree" tree is
downloaded, so that its crossgcc builds can be re-used
to save time when building targets across many trees.
this is because trees often use identical crossgcc builds.

The E6400 uses a 100 MHz reference clock on DPLL_REF_SSCLK, whereas
libgfxinit assumed that the reference was always 96 MHz. The frequency
difference caused by a 100 MHz reference with PLL config values
calculated assuming a 96 MHz reference were not significant enough to
cause noticable issues with the more common 1280 x 800 panels, but are
enough to matter for the 1440 x 900 panels which use a higher pixel
clock. This only affected the pre-OS graphics environment provided by
libgfxinit, as Linux drivers would determine the reference clock
frequency based on data in the VBT.
Fix this by making the reference clock frequency in libgfxinit
configurable for GM45 based on a new coreboot Kconfig, which is set to
100 MHz for the E6400.

for single-tree project (e.g. flashprog):
config/submodule/PROJECT/MODNAME/patches
for multi-tree project (e.g. coreboot):
config/submodule/PROJECT/TREE/MODNAME/patches
MODNAME is e.g.:
3rdparty/vboot directory in coreboot: would become vboot
(the submodule codepath is filtered to up to the final slash)
another example:
submodire src dir 3rdparty/foo/bar
MODNAME would be "bar"
Add whatever patches you like to a given submodule.
An example patch is included in this commit.

the function is very small and only called once,
from fetch_project_trees()
merge it into fetch_project_trees()

one of the calling functions relies on the return value
to be always 0, so these error conditions in mkrom_tarball
have been altered to cause an *exit* (non-zero) instead.
in practise, the commands in question were printf commands
run after tho directory they output to had been created,
so write access would probably not be an issue.
nonetheless, technically correct is the best kind of correct.

failing. we must provide feedback to the user.

The build system already deletes .git in all source
directories for each given release, but does so at
the very end; it still does, but now it is deleted
one by one per project, to save space during very
large builds (release sizes vary wildly, depending
on how many trees exist for coreboot basically).
If you're building entirely in tmpfs (as I do), this
could be a problem if you have lots of .git/ directories.
This change reduces disk usage, or in the above example,
memory usage when running the build system from tmpfs.
This complements another recent change, where ROM images
are compressed per target during release builds, rather
than all at the very end of the process. It is part of a
series of optimisations, to reduce the memory and disk
usage of the build system, and to reduce I/O wastage
in general.
This change will not be the last of such changes!

when running the inject logic, we should still initialise
the git repository because these commands make use of the
coreboot build system which requires git.

an equivalent change has been made in cbmk.
certain lbmk-specific variable names have been made
generic, with certain functions and other variables
moved around.
i maintain sync between libreboot and canoeboot, where
both projects can have the same behaviours, and most of
the merge conflicts have to do with variable names
containing "LBMK", "lbmk", "cbmk" or "CBMK", or
indeed "canoeboot" and "libreboot"
LBMK/lbmk/CBMK/cbmk variables between canoeboot and
libreboot now contain the string XBMK/xbmk
it should now be *much* easier to merge build system
changes between lbmk and cbmk.

i always say, code should never document itself.
that's what documentation is for. the releases
contain documentation under docs/ but the git
repository does not; for that, use the website.
(in practise, lbmk usually needs internet anyway)

it's only used from main() in the main build script,
and it's very small, as is main()
therefore, move the logic into main()

it's a pointless feature, initially added just to one-up
gnuboot and only intended for canoeboot, to provide u-boot
tarballs with deblobbing. this was done, because the parabola
build system has certain limitations so the idea is to provide
them with tarballs. but why? they can just fix their build system...
delete this bloat from lbmk. we only need to provide full sources,
and rom images.

in lbmk, we call check_project() to set variables
such as projectname, version, version date
this is unnecessary, because all main scripts use
this functionality anyway
do it by default

releases aren't reproducible anyway. we were
using options available in gnu tar for this.
it will be revisited at a later date. however, the next
time this is done, we will use another method because
there are in fact portable ways to create tarballs
reproducibly, documented on reproducible-builds.org
to be revisited, at a later date. for now, remove bloat.

it's only called once, from this file, within a small
function, and the function itself is very small.
remove, and put the contents of the function in the
calling function.

this function is not needed, because it's only called
once and it's very small.
furthermore: insert_version_files does ntot need to be called here,
because they same files are generated immediately afterward when
running that version of lbmk.

export LBMK_RELEASE="y"
if this is done, the tarball is created instead
of a directory, and the rom images are nuked using
./vendor inject with the nuke option, inserting the
correct version files; the rom directory is deleted
now the release script logic simple renames existing
tarballs. the benefit of this change is fewer lines of
code, and now lbmk doesn't use an insane amount of disk
space when building a *lot* of release images (the
uncompressed directories are deleted after each build)
