there are only two scripts under script/ now, and there
probably won't be many more. lbmk's design has simplified
to such a degree that the two-level directory structure is
no longer necessary.
the existing command structure has not changed. for example:
./build roms list
./update trees -f coreboot default
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:
./build roms all
./update roms all
these now do the exact same thing, whereas "./update roms all"
would have previously been an invalid command.

the main script isn't that big, and since the main
purpose of lbmk is geared toward the releases, it
makes sense to reduce the number of scripts by
merging into the main one
the way this works, "./update release" still works
afterward
so, the way lbmk is used shall remain unchanged

previous command:
./build serprog
now it is:
./build roms serprog
after that, it's the same arguments e.g.
./build roms serprog stm32
./build roms serprog rp2040

just to ensure that nothing goes wrong. we don't rely on
the status variable for releases, because there is another
variable, release, that target.cfg files declare, e.g.
release="n"
release="y"
you can just omit the variable, because it defaults to y, so
you only need declare it when it needs to be "n"

release="n" is set in target.cfg on haswell build targets
that use mrc.bin
script/update/release exports LBMK_RELEASE="y"
script/build/roms skips building a given target if release="n"
in target.cfg *and* LBMK_RELEASE="y"
you could also do the export yourself before running ./build roms,
for example:
export LBMK_RELEASE="y"
./build roms all
This would skip these ROM images. The native haswell raminit is
now stable enough in my testing, that I wish to delete the MRC-based
targets. This is in line with Libreboot's Binary Blob Reduction Policy,
which states: if a blob can be avoided, it should be avoided.
The problem is that users often run the inject script in *lbmk* from
Git, instead of from the src release archive. I forsee some users
running this on modern lbmk with older release images. If the mrc-based
target isn't there, the user may use an NRI-based target name, and
think it works; they will insert without MRC. I foresaw this ages
ago, which is why Caleb and I ensured that the script checks hashes,
and hashes are included in releases.
Therefore: for the time being, keep the MRC-based configs in lbmk
but do not include images for them in releases. This can be done
indefinitely, but I'll probably remove those configs entirely at
some point.
On the following boards, Libreboot now will *only* provide NRI-based
ROM images for the following machines:
* Dell OptiPlex 9020 SFF
* Dell OptiPlex 9020 MT
* Lenovo ThinkPad T440p
* Lenovo ThinkPad W541/W540
I now recommend exclusive use of NRI-based images, on Haswell
hardware. It's stable enough in my testing, and now supports S3.

lbmk otherwise uses nproc to set the number of build threads,
in these places:
* generic make commands in script/update/trees
* crossgcc make command in script/update/trees
the -T0 option is also used in script/update/release, when running
tar.
with this change, you can do:
export LBMK_THREADS=x
where x is the number of threads. when you then run
lbmk, your chosen number of threads will override
the default. this may be useful on a host that does
not have a lot of memory.

in shell scripts, a function named the same as a program included in
the $PATH will override that program. for example, you could make a
function called ls() and this would override the standand "ls".
in lbmk, a part of it was first trying to run the "fail" command,
deferring to "err", because some scripts call fail() which does
some minor cleanup before calling err.
in most cases, fail() is not defined, and it's possible that the user
could have a program called "fail" in their $PATH, the behaviour of
which we could not determine, and it could have disastrous effects.
lbmk error handling has been re-engineered in such a way that the
err function is defined in a variable, which defaults to err_ which
calls err_, so defined under include/err.sh.
in functions that require cleanup prior to error handling, a fail()
function is still defined, and err is overridden, thus:
err="fail"
this change has made xx_() obsolete, so now only x_ is used. the x_
function is a wrapper that can be used to run a command and exit with
non-zero status (from lbmk) if the command fails. the xx_ command
did the same thing, but called fail() which would have called err();
now everything is $err
example:
rm -f "$filename" || err "could not delete file"
this would now be:
rm -f "$filename" || $err "could not delete file"
overriding of err= must be done *after* including err.sh. for
example:
err="fail"
. "include/err.sh"
^ this is wrong. instead, one must do:
. "include/err.sh"
err="fail"
this is because err is set as a global variable under err.sh
the new error handling is much cleaner, and safer. it also reduces
the chance of mistakes such as: calling err when you meant to
call fail. this is because the standard way is now to call $err,
so you set err="fail" at the top of the script and all is well.

in some cases, the build system was needlessly, and sometimes
erroneously, creating crossgcc symlinks, which then caused an
issue, namely:
in lbmk release builds, dell e6400 is build before fam15h boards,
and it sets xtree, but fam15h_rdimm doesn't, and later this would
cause fam15h_rdimm boards to use xtree="default" (because they don't
set xtree), causing the newer toolchain to be used on coreboot 4.11.
this patch fixes the issue. quite a simple problem, actually.

with neutered ME, fan control fails. while there are
ways to mitigate it, many users will not, and will
likely see their system overheat, which is very
dangerous.
this bug (failed fan control on neutered ME) only
affects arrandale machines such as lenovo x201.
the newer machines are not affected by this.
other arrandale machines will probably not be added
to libreboot because of this, or they will be subject
to further testing.

this is now used in grub, for the FS_PAYLOAD_MODULES
option in the make command
lbmk should generalise as much logic as possible. in
some parts of it, logic is hurrently hardcoded, specific
to a given project that lbmk uses, but lbmk is essentially
a source-based package manager, like what you might find
on a small linux distro, so we need to try to
be as generic as possible.
lbmk is the "build system of build systems", so it has to
work generically with as many of them as possible

it is no longer hardcoded just to be handled for uefiextract.
it is now defined as cmakedir in target.cfg, for a single or
multi tree project. if multi tree, it is applied to the specific
tree, and has to be defined per tree
the way it works is: as per cmakelist, a project will define
which directory is to be built, and it will then generate
a makefile in the main source tree (the build tree in cmake
language, where the main CMakeLists.txt file exists)
when the makefile has been generated, the project is then treated
like any other project. the way cmake works, if a makefile has
already been generated by it, in a given directory, running it
again will fail and not affect anything; if it fails but the
makefile doesn't exist, then something is wrong, but if the
makefile does exist, then it's all fine and nothing happens
at present, this is only used for uefiextract, which is part
of src/uefitool

at present, the bootstrap and configure script is only
directly executed for grub, because grub is the only
project that uses them in lbmk
however, when i start adding linuxboot support, i will
have to start building a lot of projects, some of which
make use autoconf and bootstrap scripts
e.g.
./bootstrap --foo
./configure --bar
the "bootstrap" script is often used on GNU programs,
because they like to over-engineer absolutely everything

arch no longer needs to be set, on multi-tree projects,
and it has been renamed to xarch
the new behaviour is: if xarch is set, treat it as a
list of crossgcc targets and go through the list. set
the first one as the target, for what lbmk builds, but
build all of the defined crossgccc targets
crossgcc_ada is now xlang, and defines which languages
to build, rather than whether to build gcc-gnat

err.sh, but now it's handled there by a function,
which is called by the main script.

when make-all is being executed on a coreboot tree,
the "./vendor download target" command is used, where
target is the tree/board name.
that script then checks whether cbfstool and ifdtool
are built, and if they're not, they then call
./update trees -b coreboot utils bla bla bla
in this scenario, project=coreboot and mode="", meaning
make-all, and the same check that checks whether the
vendor download script should be run, is executed,
which in turn then checks cbutils again
fix the infinite loop by checking whether it was coreboot
utils, as opposed to *firmware*, that is to be built, before
running ./vendor download

at present, lbmk can remove microcode updates on images for
a given target, if the target specifies
microcode_required="n" in target.cfg
lbmk then provides images with microcode, and images without,
in a given release. although the user can also remove them
manually, this just makes it a bit more convenient, for those
users who do wish to run without the updates. this functionality
is provided only on those platforms where no-microcode is tested.
well, this behaviour implements a compromise on libreboot policy,
which is to always include microcode updates by default. see:
Binary Blob Reduction Policy
the *canoeboot* project now exists, developed in parallel with
libreboot, and it ships without microcode updates, on the same
targets where lbmk also handled this.
running without microcode updates is foolish, and should not
be encouraged. clean up lbmk by not providing this kludge.
the libreboot documentation will be updated, telling such users
to try canoeboot instead, or to remove the update from a given
libreboot rom - this is still possible, and mitigations such as
PECI disablement on GM45 are still in place (and will be kept),
so that this continues to work well.

the purpose of script/update/release is not to test the
build system, but to build release archives.
testing of lbmk is done during the course of development.
remove this bloat from the release script. we run the nuke
mode anyway, to scrub blobs from releases, which will more
or less test the logic in that script (the only difference
is that it runs e.g. ifdtool --nuke instead of -i).

don't handle "romtype" at all, in board target.cfg files
add /dev/null as pike2008 rom on amd boards. this serves
the same purpose, adding them as empty vga roms, to add
an empty rom in cbfs. pike2008 cards cause seabios to hang,
when their oproms are executed, so we insert a fake rom
on i945 thinkpads, use the coreboot config option:
CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK
when set, this enables the same bootblock copy, for use
with bucts. these two cases, namely pike2008 roms and

only call crossgcc for coreboot and u-boot, but use
hostcc for everything else. simplify the checking of
which architecture to compile for. "arch" in target.cfg
files has been modified, to allow further simplification.
without this patch, the logic currently only *barely* avoids
using crossgcc on things like utils, and only works in practise
because, in practise, lbmk only works on x86_64 anyway.
the new logic, as per this patch, is simpler and more robust.
