| * The PSA and Mbed TLS error space are now unified. This means that | |
| mbedtls_xxx() functions can return PSA_ERROR_xxx values. | |
| There is no longer a distinction between "low-level" and "high-level" | |
| Mbed TLS error codes.. | |
| This will not affect most applications since in both cases, the | |
| error values are between -32767 and -1 as before. |
