There are a few instances of MBEDTLS_*_C (specifically for DES) in
psa_crypto.c. Change to the PSA_WANT_KEY_TYPE_DES macros to reflect the
new PSA crypto config.

Add additional ifdef checks in the PSA config to detect when an
algorithm is entirely implemented in hardware. If there is any
combination of cipher and padding type that is not supported by the HW
acceleration, enable the SW acceleration.

This file will always be used with the PSA configurations, so use the
MBEDTLS_PSA_BUILTIN... definitions for the symmetric cyphers.

PSA defines CBC with no padding, and CBC with PKCS7 padding. The bare
"ALG_CBC" is not defined, so remove this definition.

For the new features conditionalized on MBEDTLS_PSA_ACCEL_..., define a
correlated MBEDTLS_PSA_BUILTIN_... if it is not defined. This prevents
check_names from considering these new defines as typos.

Add support for supported block modes using the PSA crypto config.
These are mapped to Mbed TLS config options as best as possible.

Update the psa/crypto_config.h with the newly defined PSA_WANT_
definitions for symmetric ciphers and block modes.

There was some intentional duplication between
library/psa_crypto_random_impl.h and include/mbedtls/psa_util.h, with
the intent that the compiler would complain if one file was edited in
a way that's incompatible with the other file. However, the two files
were never included together, and in fact could not be included
together because some definitions can't be duplicated (type, static
variable).
Now library/psa_crypto_random_impl.h includes
include/mbedtls/psa_util.h, so the compiler will check what it can.
There is less redundancy since it isn't always possible to declare
something twice (specifically, types can't be declared).

The SSL test programs can now use the PSA RNG, and the PSA RNG can use
an external RNG. The build conditions hadn't been updated and didn't
cover the case when MBEDTLS_TEST_USE_PSA_CRYPTO_RNG is enabled but
MBEDTLS_USE_PSA_CRYPTO is disabled. Fix this.

The point of having an external RNG is that you can disable all
built-in RNG functionality: both the entropy part and the DRBG part.

The dependency is on MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG plus
MBEDTLS_PSA_CRYPTO_C. MBEDTLS_USE_PSA_CRYPTO is irrelevant.

Move the call to destroy the PSK to before freeing the SSL session
data and calling rng_free(), which deinitializes the PSA subsystem.
This particular ordering was chosen to make the ssl_client2 more
similar to ssl_server2. This fixes the client failing on the
psa_destroy_key() call in `ssl-opt.sh -f 'opaque psk on client'`.

The SSL test programs can now use mbedtls_psa_get_random() rather than
entropy+DRBG as a random generator. This happens if
the configuration option MBEDTLS_USE_PSA_CRYPTO is enabled, or if
MBEDTLS_TEST_USE_PSA_CRYPTO_RNG is set at build time.

Use PSA_EXPORT_KEY_OUTPUT_SIZE macro to compute the

instead of computing it alongside the key type and

Extend import/export/generate key through a PSA
transparent driver without software fallback
testing to RSA keys.

Now that the support for key generation in the transparent
test driver is at the same level as the support in the
Mbed TLS library, remove the restriction on the generate
key test case that was introduced by the work on key
import and export through the PSA driver interface.

Add a test in test_suite_psa_crypto_driver_wrappers that
when accelerators do not support the generation of a key
and there is no software fallback, the key generation
fails with the PSA_ERROR_NOT_SUPPORTED error code.
Signed-off-by: Ronald Cron <ronald.cron@arm.com>
When generating transparent keys, we need to be able
to compute the size of the key buffer whether the
key is generated by the Mbed TLS library or by an
accelerator. Thus, change the RSA/ECP
MBEDTLS_PSA_BUILTIN_... compilation guards with
their PSA_WANT_... counterparts.
