[PATCH] arch/arm/boards: Replace license and copyright boilerplate by SPDX identfiers

[PATCH] arch/arm/boards: Replace license and copyright boilerplate by SPDX identfiers

[Uwe Kleine-König]

This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.

The advantage is that these specifiers are machine-parseable which helps
license conformance, e.g. for packaging barebox in Debian.

While touching these files also do some minor comment reformatting to
get some uniform layout.

I'm unsure (and didn't add SPDX-FileCopyrightText consistently for these
(I hope)). Is the copyright "infecting" in this way? What is your
suggestion?

huch, I guess I first removed the comment about u-boot and then readded
it during my own review at the wrong place. Will fix.

Right, I didn't use a , as the email address looked as if it covered
both persons. An alternative I considered is to use two lines for the
two developpers and duplicate the email address. I don't like s/&/,/ as
after a name and a comma in all other locations a company only follows.

Best regards
Uwe

Yes. "based on" suggests to me "I copied the file and adapted it", so
the copyright lines from the copied file probably still apply – at least
I would count on it until we can disprove it (which we probably won't).
Further down in your patch we also had an "inspired by", but I don't
think that language is strong enough to warrant a copyright line.

Yeah, I don't have a favourite here either.

Hmmm, I don't see why you dropped the following files from your

Uhm, this was meant for v2, but I replied to the wrong thread, but your
v2 also didn't have "v2" in the subject, so I got confused :P

I didn't recheck them all, but my intention was to not modify files that
look like:

	Copyright (C) $year $someone

	based on path/to/another/file
	Copryright (C) $earlieryear $someoneelse

because I'm not 100% sure if the latter copyright line should be
included. So the plan was to first get the low-hanging fruit done and
then address the harder cases.

Best regards
Uwe

While going further through the barebox source tree there are more files
with this info. Last I found was

	arch/arm/cpu/no-mmu.c

Would be really great to get some input from you on this.

Best regards

There were some comments on the old thread (see
<20200523150007.erjwm3azjdyaywx4@pengutronix.de>), which didn't get
answered yet – are those resolved?

While going once more through this patch I noticed that there are a few
hunks that might be questionable and it would be great if you could
comment:

Is this right? I.e does Zodiac hold the copyright and you are "only" the
author? Or would

	// SPDX-FileCopyrightText: 2017 Andrey Smirnov <andrew.smirnov@gmail.com>, Zodiac Inflight Innovation

be more appropriate?

Same question for

[PATCH] arch/arm/boards: Replace license and copyright boilerplate by SPDX identfiers

[Uwe Kleine-König]

This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.

The advantage is that these specifiers are machine-parseable which helps
license conformance, e.g. for packaging barebox in Debian.

While touching these files also do some minor comment reformatting to
get some uniform layout.
