This is useful for e.g. HP EliteBook 2560p.
In coreboot config, enable e.g. (for lbmk blobutil):
CONFIG_KBC1126_FW1="../../ec/hp2560p/ec.bin.fw1"
CONFIG_KBC1126_FW2="../../ec/hp2560p/ec.bin.fw2"
In resources/blobs/sources you would have these entries:
EC_url
EC_url_bkup
EC_hash
don't download it. keep it in lbmk.
libreboot moved to codeberg for git hosting,
and i didn't want to keep lugging around an
extra git repo just for one tiny project.
libre mrc on haswell is quite buggy for now, but works in
a limited fashion
this patch re-adds the old configs, but as _mrc for example
t440p_12mb_mrc instead of t440p_12mb
and t440p_12mb (without _mrc) still uses the libre mrc code
courtesy of Angel Pons from the coreboot project
this uses the following patch set from gerrit, as yet
unmerged (in coreboot master) on this date:
https://review.coreboot.org/c/coreboot/+/64198/5
logic for downloading mrc blobs has been deleted from
lbmk, as this is now completely obsolete (for haswell
boards)
if other platforms are added later that need mrc.bin,
then logic will be re-added again for that
some checks check for specific utils, which are
then used to indicate the existence of other utils,
which means that building them singularly, as is
currently done, may result in errors later if another
tool doesn't exist compiled yet
this is an obscure bug, fixed by this patch. more of a
workaround really. a dirty hack. when checking for any
of the coreboot utilities required, build all coreboot
utilities that are possibly required
the utilities are small enough that this does not add
much extra time to build, and in most cases, all of them
will be needed anyway
By making lbmk fully POSIX-compliant, it will be easier to port lbmk to
other systems implementing POSIX such as Alpine Linux and FreeBSD.

Add U-Boot to the source release script's modules list so that it is
included in source release tarballs. Don't include the unused upstream
source and .git directories.

this is a hangover from pre-osboot-merge libreboot. the idea
was to distribute fsdg uboot archives
lbmk has uboot support, and releases will simply
include uboot in the main src archive like with everything else
the --nuke option in ifdtool will be used instead, to nuke
the ME regions in specific rom sets (and cbfstool will be
used to delete mrc.bin files from rom sets)
the new method being implemented is heavier on disk io, but
simplifies lbmk, and disk io could still be optimised in
the following ways:
* when copying roms from boards with ME in them, use
ifdtool --nuke to get filename.rom.new, and *move* (not copy)
filename.rom.new to the new destination (for use with tar)
* possibly modify ifdtool to make efficient use of mmap for
disk i/o; it currently loads entire roms into an allocated
buffer in memory
Add a 'v2022.07' pseudo-board for the U-Boot download script with the
default blobs list, and mark the version as supported in u-boot-libre
release script.

The U-Boot download script is designed to help with releasing
u-boot-libre and it can only prepare a generic U-Boot v2021.07 tree.
However, we will need to build board-specific versions of U-Boot to be
able to use it as a coreboot payload effectively.
As a first step toward that, make the download script prepare per-board
copies of U-Boot v2021.07. Then, add a 'v2021.07' pseudo-board for the
u-boot-libre release script to work on.
The u-boot-libre deblob script hash ends up chaning due to copying my
author attribution from the download script, update its hash.

The u-boot-libre tarball contents' mtimes are an unconventional value
due to timezone confusion. For reproducibility, timestamps like these
are usually set by a SOURCE_DATE_EPOCH which is respected by both
coreboot and U-Boot. Use it in the u-boot-libre release script as well,
and properly set the mtimes to the Unix epoch when it's not defined.

The u-boot-libre release script copies the blobs list into the release
as the deblob script, presumably due to a copy-paste error. Fix it to
correctly copy the generated deblob script.

The checksums in tests/u-boot-libre.sha512 do not match the tarballs
generated by this script when ran on a different timezone, e.g. UTC+3.
Explicitly specify a timezone for the tar command that makes the
tarballs match the checksums.

Many people using FSDG compliant distributions or wanting to use one
are already familiar with linux-libre. This change renames the
resulting tarball to u-boot-libre to make it easier for people to
understand the goal of this tarball.
In addition we also rename the version from v2021.07 (which is the git
tag corresponding to the release) to 2021.07 as u-boot upstream
tarballs use that.
The revision wasn't bumped as we didn't have any releases of
u-boot-libre yet.

Once the tarball are released, it will enable distributions to use
these tarballs to produce deblobbed u-boot packages.
Note that the produced tarball is not reproducible yet. Because of
that it has to be trusted.
During a release, it's a good idea to sign the uncompressed tarball as
the various compression formats and associated tools make different
tradeoffs.
For instance with xz, xz -9e tends to compress really well with the
the most used xz[1] implementation, and most GNU/Linux users probably
already have it installed, but and the drawbacks is that the format is
very fragile[2].
The lzip format is more suited for long term archiving but its most
packaged implementation[3] is less likely to be already installed by
users than more well known formats like xz, bzip2 or gzip.
Being able to add more compression formats after the release is also
useful, for instance to accommodate different build systems or use
cases (like being able to build u-boot with less dependencies in
distributions like Guix, or building u-boot directly on devices which
don't have enough RAM for xz for instance).

tianocore is a liability for the libreboot project. it's a bloated mess, and
unreliable, broken on many boards, and basically impossible to audit.
i don't trust tianocore, so i'm removing it.
this is forked from the "libre" branch in osboot, which is itself a libre,
deblobbed fork of osboot, a blobbed up fork of libreboot
libreboot needed to be purged clean. this is the new libreboot development
repository. the old one has been abandoned
