*
* \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.
