This includes structure definitions in `psa/crypto_struct.h`, size calculations in `psa/crypto_sizes.h`, and application code that's specific to a given cryptographic mechanism. In Mbed TLS itself, code under `MBEDTLS_USE_PSA_CRYPTO` and conditional compilation guards in tests and sample programs need `PSA_WANT_xxx`.
