The files within the p256-m/ subdirectory originate from the p256-m GitHub repository. They are distributed here under a dual Apache-2.0 OR GPL-2.0-or-later license. They are authored by Manuel Pégourié-Gonnard. p256-m is a minimalistic implementation of ECDH and ECDSA on NIST P-256, especially suited to constrained 32-bit environments. Mbed TLS documentation for integrating drivers uses p256-m as an example of a software accelerator, and describes how it can be integrated alongside Mbed TLS. It should be noted that p256-m files in the Mbed TLS repo will not be updated regularly, so they may not have fixes and improvements present in the upstream project.
The files p256-m.c, p256-m.h and README.md have been taken from the p256-m repository.
It should be noted that p256-m deliberately does not supply its own cryptographically secure RNG function. As a result, the PSA RNG is used, with p256_generate_random() wrapping psa_generate_random().
