* \brief PSA cryptography module: invasive interfaces for test only.
* The interfaces in this file are intended for testing purposes only.
* They MUST NOT be made available to clients over IPC in integrations
* with isolation, and they SHOULD NOT be made available in library
* integrations except when building the library for testing.

/** \brief Configure entropy sources.
* This function may only be called before a call to psa_crypto_init(),
* or after a call to mbedtls_psa_crypto_free() and before any
* subsequent call to psa_crypto_init().
* This function is only intended for test purposes. The functionality
* it provides is also useful for system integrators, but
* system integrators should configure entropy drivers instead of
* breaking through to the Mbed TLS API.
* \param entropy_init Function to initialize the entropy context
* and set up the desired entropy sources.
* It is called by psa_crypto_init().
* By default this is mbedtls_entropy_init().
* This function cannot report failures directly.
* To indicate a failure, set the entropy context
* to a state where mbedtls_entropy_func() will
* return an error.
* \param entropy_free Function to free the entropy context
* and associated resources.
* It is called by mbedtls_psa_crypto_free().
* By default this is mbedtls_entropy_free().
* \retval #PSA_SUCCESS
* Success.
* The caller does not have the permission to configure
* entropy sources.
* The library has already been initialized.
