Hello,

In addition to the already proposed copyright note update, an alternative form was presented at the Tech Forum today. The form shown below is simpler and even more in line with Linux Foundation guidelines. It is already supported by several TrustedFirmware projects, making it a better option for us.

Please comment here or in Gerrit, already updated to this option.

Here is the copy of the new wording:

Ensure that each changed file has the correct copyright and license information. Files that entirely consist of contributions to this project should have a copyright notice and BSD-3-Clause SPDX license identifier of the form

SPDX-License-Identifier: BSD-3-Clause

SPDX-FileCopyrightText: Copyright The TrustedFirmware-M Contributors

to reflect the community ownership of the project. Individual copyrights can be traced back through the corresponding commits. For more details please refer to Linux Foundation guidelines on copyright notices for OSS projects. Patches that contain changes to imported Third Party IP files should retain their original copyright and license notices. If changes are made to the imported files, then add an additional SPDX-FileCopyrightText tag line as shown above.

The original form of the project copyright note as

is still appropriate but shall be avoided in the new files.

Thanks and best regards,

Anton

Please share your thoughts on the subject. I plan to bring this topic to the tech forum agenda on Thursday. Please join the discussion.

Thanks,
