* \def CONFIG_TFM_CRYPTO_API_RENAME
*
* \brief By setting this to 1, system integrators can rename the symbols of the
* PSA Crypto APIs available in the TF-M interface. It allows flexibility
* for some integration setups where multiple providers of the PSA Crypto
* APIs are available at link time. Normally this configuration option
* should not be enabled when building the Secure interface because the
* secure partitions will just use the standard function names. By default
* it prepends the "tfm_crypto__" prefix.
*
* \note This config option is not available through the TF-M configuration as
* it's for NS applications and system integrators to enable.
