i'm going to move the config recursion check
into a separate function, and global variables
make it easier to handle

this fixes a regression caused in previous (recent)
revisions. this script is a beast, and requires a
lot of taming, which is the purpose of my audit

yes, i know 3676 supersedes 2646
i still say 2646
saying 2646 is still technically valid,
for my purposes

the cbfstool command within subshell now also
exits with non-zero status, if it fails (most
likely because extraction failed, for some reason,
of the coreboot rom image for running through it)
|
|
the previous code merely exited from the subshell,
but the intended behaviour is for the entire script
to halt execution, and exit with non-zero status.
this patch fixes that bug.

top-down order for all logic, and shorter code lines,
conforming to rfc 2646 (no more than 80 characters)
the 80-character rule is violated for variables containing
long strings, such as wayback machine urls (can't be helped)
a few bugs were discovered, which will be fixed in follow-up
revisions, such as:
* exit status not handled inside subshell
* in general, exit status should be handled
more explicitly, rather than relying on -e

for our purposes, grub and gnulib are one in the same
if one fails, both have failed
exit with non-zero status if gnulib fails
the script sets -e so it will fail if grub fails to
download, which is tried before gnulib, and if that
happens, the grub directory is not created

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

this fixes the build error:
Error: name not set
Usage: ./download gitmodule [name]
when running:
./download all
running "all" runs all scripts under downloads,
one of which was the gitmodule script itself, therefore
being run without argument

The U-Boot download script does its work from the repository root
instead going into the newly created dirs, unlike the coreboot
counterpart. It should run the board-specific extra.sh files with the
downloaded paths as their working directory. Do so by a subshell.

The no-argument form of the U-Boot download script prepare trees for all
boards when run with no arguments, like the corresponding script for
coreboot. The usage text for this case was removed without any changes
to the corresponding code, assume it was by mistake and add it back.

Removing the git dirs was part of deblobbing, which Libreboot no longer
cares about. The variable that triggers it is no more. Remove the dead
code.

osboot is now part of libreboot, and will soon shut down.
libreboot now conforms to osboot policy.

Downloading coreboot and U-Boot takes quite the disk space and bandwith.
We don't need to download entire repos, only the revisions that we are
interested in.
Use the --depth=1 option to only download the files we need. Since the
initial clones may not have our target revision, always try to fetch it.

Keeping the git repositories is useful while development, e.g. to avoid
git cloning repositories over and over again while debugging download
scripts. Setting the NODELETE environment variable keeps the blobs and
the git repositories. Allow a slightly finer-tuned version of this where
we can keep only the git-related files by setting the variable to "git".

The coreboot download removes .git folders as they still contain the
removed blobs, remove those in the U-Boot version as well.

Although it's unlikely, boards might want to run extra commands after
the board-specific U-Boot directories are prepared. Copy the existing
mechanism for that from the coreboot download script to the U-Boot one.

Boards may need different sets of patches to be applied to their U-Boot
builds, copy the existing mechanism from the coreboot download script to

The coreboot download script tries to update submodules, since coreboot
does use git submodules to retrieve and compile the projects it depends
on. Although U-Boot doesn't use submodules, try to update them anyway to
match the coreboot download script.

The coreboot download script uses GitHub as a fallback if the upstream
coreboot is unavailable, use a similar fallback for U-Boot as well.

Boards may want to specify a board-specific U-Boot revision. At the very
least, pseudo-boards for u-boot-libre releases will need to specify their
U-Boot versions somehow.
Copy the existing mechanism from download/coreboot for specifying
build info with board.cfg files. Specify the commit hash for the
'v2021.07' pseudo-board, and 'master' as the default.

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.

When running ./download all, we have the following error:
resources/scripts/download/coreboot: Line 52: $1 is not set.
The ./download all command was broken by the following commit:
2bb805e2e07a7d3e1268a09d720ecd13e26af418 (download: Add --help in the
individual download scripts).

This doesn't change the existing usage of the scripts:
- For the Coreboot script, before this change, all arguments that were
passed were considered as board to download the Coreboot source code
for.
Here we added the '--help' and '--list-boards' arguments, so it
should not be an issue as it is extremely unlikely that a board
would be called '--help' or '--list-boards'.
- All the other scripts don't use any arguments so passing --help
should not conflict with the existing usage.

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).
