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>

2022-02-16boot-libre: add --gen-blob-script to generate a deblob scriptDenis 'GNUtoo' Carikli
This should enable various distributions and build system to reuse the generated script to deblob u-boot releases themselves. Signed-off-by: Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org>

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).
