Summary

All files in this directory are distributed under the normal Mbed TLS dual Apache 2.0 or GPLv2-or-later license, and are copyright The Mbed TLS Contributors.

Background

The two files crypto_config_profile_medium.h and tfm_mbedcrypto_config_profile_medium.h are taken verbatim from the TF-M source code here:

https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git/tree/lib/ext/mbedcrypto/mbedcrypto_config

In TF-M, they are distributed under a 3-Clause BSD license, as noted at the top of the files.

In Mbed TLS, with permission from the TF-M project, they are distributed under a dual Apache-2.0 OR GPL-2.0-or-later license, with copyright assigned to The Mbed TLS Contributors.

We only retain the note at the top of the files because we are taking the files un-modified, for ease of maintenance.
