This patch set contains various improvements to the scripts to do u-boot tarball releases.
In addition it also adds tests for it: since the tarballs should be reproducible it's a good idea to have tests.
I also added --help in all the download scripts while I was at it.
I'm not sure if that works with pull request but I also tagged the 8833be159b commit (scripts: download: u-boot: fix u-boot repository URL) as u-boot-libre-2021.07-r1.
Then the next step will be to actually release the files on the mirrors.
looks good to me. merging
