pragmatic system distribution guideline compliance

2022-11-14T00:51:12+00:00

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

download: Use shallow clones for big projects

2022-08-27T14:35:55+00:00

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.

download: Allow keeping .git dirs with NODELETE=git

2022-08-27T14:35:55+00:00

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".

download/u-boot: Remove .git folders as well

2022-08-27T14:35:55+00:00

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

download/u-boot: Support running extra commands from board dirs

2022-08-27T14:35:55+00:00

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.

download/u-boot: Support applying patches from board dirs

2022-08-27T14:35:55+00:00

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 U-Boot download script.

download/u-boot: Try to update submodules as in coreboot script

2022-08-27T14:35:55+00:00

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.

download/u-boot: Use GitHub mirror as fallback

2022-08-27T14:35:55+00:00

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

download/u-boot: Support reading tree and revision from board.cfg

2022-08-27T14:35:55+00:00

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.

download/u-boot: Prepare files per board instead of per revision

2022-08-27T14:35:55+00:00

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.
