+/** \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.
+ * \retval #PSA_ERROR_NOT_PERMITTED
+ *         The caller does not have the permission to configure
+ *         entropy sources.
+ * \retval #PSA_ERROR_BAD_STATE
+ *         The library has already been initialized.
