It's worth mentioning that the repository you point at here needs to be
checked out at the very same state that it was when you copied the file.

In other words, there is no magic that tries to match the barebox
version of the file to the closest linux/u-boot/... revision of the
file.

It's a thing to remember when somebody reminds you of adding the
origin-URL in a review and you call the script a week later when your
Linux repository already has another revision checked out.
