e6e6b75ad3 psa: Remove MBEDTLS_PSA_CRYPTO_DRIVERS configuration option
The support for the PSA crypto driver interface
is not optional anymore as the implementation of
the PSA cryptography interface has been restructured
around the PSA crypto driver interface (see
psa-crypto-implementation-structure.md). There is
thus no purpose for the configuration options
MBEDTLS_PSA_CRYPTO_DRIVERS anymore.

382b34ca84 Work out the hash interface requirements
Finish working out the RSA-PSS example in terms of what it implies about the

algorithms if they are available through either interface, and that's all
there is to it. The details of how dispatch is done don't matter, what
matters is only the availability, and it's just the disjunction of
availabilities.

Instead of having a list of test suites of interest, have a list of

In order for this to only yield interesting results, we need to tune the
reference configuration a bit, in order to exclude STREAM and ECB to
more closely match the driver-based configuration.

c0d78e9e69 Remove outdated paragraphs about G5
- lack of support for PSA_CRYPTO_CONFIG is not really a reason not to
enable MBEDTLS_USE_PSA_CRYPTO by default - while it's true that
currently X.509/TLS do not behave as expected when PSA_CRYPTO_CONFIG and
MBEDTLS_USE_PSA_CRYPTO are both enabled, it's no worse than when
MBEDTLS_USE_PSA_CRYPTO is disabled.
- as a consequence of removing the paragraph mentioned above, the
sub-section about PSA_CRYPTO_CONFIG no longer belongs in the
"compile-time option" section. Also, it's superseded by the study work
that happened in the meantime (of which this PR is part). So let's
remove it, and the new commit will add something more up-to-date
instead.

since TLS 1.3 does not support PSK at all so far, and it is expected to
support opaque PSKs as soon as it gains PSK support, it will be just a
matter of selecting between psa_key_derivation_input_bytes() and

ff43ff6e78 Remove stability waiver from USE_PSA
It was initially motivated by the fact that the PSA Crypto APIs
themselves were not stable. In the meantime, PSA Crypto has reached
1.0.0 so this no longer applies.

If we want user to be able to fully benefit from PSA in order to
isolate long-term secrets, they need to be able to use the new APIs with
confidence. There is no reason to think those APIs are any more likely
to change than any of our other APIs, and if they do, we'll follow the
normal process (deprecated in favour of a new variant).

For reference, the APIs in question are:

mbedtls_pk_setup_opaque() // to use PSA-held ECDSA/RSA keys in TLS

mbedtls_ssl_conf_psk_opaque()   // for PSA-held PSKs in TLS
mbedtls_ssl_set_hs_psk_opaque() // for PSA-held PSKs in TLS

mbedtls_cipher_setup_psa() (deprecated in 3.2)
mbedtls_pk_wrap_as_opaque() (documented internal, to be removed in 3.2)

54eb0686b3 New function psa_crypto_driver_key_derivation_get_input_type
The new function psa_crypto_driver_key_derivation_get_input_type() allows
drivers to retrieve the effective type of each input step, and thus to call
the correct get-data function. This is simpler than the previous scheme
which required a somewhat contrived dance with get_key() and get_bytes() for
inputs that can be passed either as a key or as a byte buffer at the
application's choice.

25e39f24b9 Add section for Mbed TLS 2.25.0+
We hadn't updated the storage specification in a while. There have been no
changes to the storage layout, but the details of the contents of some
fields have changed.

Since this is now a de facto stable format (unchanged between 2.25 and 3.2),
describe it fully, avoiding references to previous versions.

Also have check_config.h enforce this. And MBEDTLS_SSL_EXPORT_KEYS has been removed,
so no longer mention it.
