2022-12-09download/u-boot: Re-add usage text for no-argument formAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-12-09download/u-boot: Remove support for deleting git foldersAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>

osboot is now part of libreboot, and will soon shut down. libreboot now conforms to osboot policy.
2022-08-27download: Use shallow clones for big projectsAlper Nebi Yasak
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.

2022-08-27download: Allow keeping .git dirs with NODELETE=gitAlper Nebi Yasak
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". Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-27download/u-boot: Remove .git folders as wellAlper Nebi Yasak
The coreboot download removes .git folders as they still contain the removed blobs, remove those in the U-Boot version as well. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-27download/u-boot: Support running extra commands from board dirsAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-27download/u-boot: Support applying patches from board dirsAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-27download/u-boot: Try to update submodules as in coreboot scriptAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-27download/u-boot: Use GitHub mirror as fallbackAlper Nebi Yasak
The coreboot download script uses GitHub as a fallback if the upstream coreboot is unavailable, use a similar fallback for U-Boot as well. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
2022-08-27download/u-boot: Support reading tree and revision from board.cfgAlper Nebi Yasak
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.

2022-08-27download/u-boot: Prepare files per board instead of per revisionAlper Nebi Yasak
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. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>

2022-02-10Add support for releasing deblobbed u-boot 2020.07 source tarballsDenis 'GNUtoo' Carikli
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).
