As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.
Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

* \brief PSA cryptography module: Mbed TLS platform definitions
|
|
*
|
|
* \note This file may not be included directly. Applications must
|
|
* include psa/crypto.h.
|
|
*
|
|
* This file contains platform-dependent type definitions.
|
|
*
|
|
* In implementations with isolation between the application and the
|
|
* cryptography module, implementers should take care to ensure that
|
|
* the definitions that are exposed to applications match what the
|
|
* module implements.
