This is something we don't want, however. We need to not be adding more
files to the source directory as part of tests. This is a general bad
practice.

And in the likely event that you're going to note that python is slow,
please try your suggestion of 2019[1] and see about making U-Boot be a
python library, and if that doesn't work, look for other ways to speed
up python? Given all of the real time machine learning demos that are
built upon Python, it seems like piping data around fast should be
something that can be solved.

You're back to editoralizing in commit messages, and since you do
provide a helper for mk_fs you also simply could for setup_image.
