At the moment it makes no difference, but it could if e.g. a new
algorithm was called 'foomask'.

By default, exclude macros whose numerical value is not a valid member
of the semantic type (e.g. PSA_ALG_xxx_BASE is not itself an
algorithm, only an intermediate value used to construct others). But
do include them with include_intermediate=True, which
generate_psa_constants.py does.

Update with CHACHA20_POLY1305, CHACHA20. Add in CTR, which was missing,

Change the psa_crypto use of the CHACHA20 cipher to also use the new

Change a few conditionals in the psa library to be based on the
MBEDTLS_PSA_BUILTIN_KEY_TYPE_DES instead of the WANT macros. Future
additions of HW acceleration will need to be mindful of these
definitions if any of this code is needed in those instances.

With the else branch commented out, both lines are unnecessary. We
could check for the invalid configuration in the future, once tests were
made to exclude this combination.

There is no PSA ALG_ECB, only ALG_ECB_NO_PADDING. Fix one incorrect
declaration, and remove another that is just redundant.

Only define MBEDTLS_CIPHER_MODE_CBC if one of the CBC modes is requested
and everything isn't covered by an accelerated version. This keeps this
from being defined in cases where everything needed would be
accelerated.

When converting definitions to use the new PSA defines, one erroneously

If any of the software block ciphers are selected, define an internal
macro to indicate this. This eliminates some redundancy that needs to
check for this.

Add checks for PSA_WANT_KEY_TYPE_CHACHA20, both with and without
MBEDTLS_PSA_CRYPTO_CONFIG. This only adds support for the ciphers
itself, presumably as a stream cipher (and not yet AEAD).

Even if there is an accelerated version of a (block) key type, enable

There are a few instances of MBEDTLS_*_C (specifically for DES) in

Add additional ifdef checks in the PSA config to detect when an
