db003f31fc Remove unused definition
PSA defines CBC with no padding, and CBC with PKCS7 padding.  The bare
"ALG_CBC" is not defined, so remove this definition.

07cc04a8ad Updates to PSA crypto library based on review comments
Moved new check_crypto_config.h file from include/psa to library
directory and the file is now included from *.c instead of the
crypto_config.h file. Fixed guards in PSA crypto library based
on review comments for new PSA crypto config features.

b6f7afcb5c Move check config feature for PSA_WANT
Moved from doing the dependency checks for MBEDTLS_PSA_BUILTIN to
checking the PSA_WANT macros for the dependency checks. This required
moving the file into the include/psa directory and having the file be
included by crypto_config.h instead of config_psa.h.

9814fa2b08 Minor updates from review comments
Updated macros in config_psa.h that used ECC_xxx to use KEY_TYPE_ECC_xxx
per comments from review. Implemented a check_config_psa.h to help with
dependency checking of features enabled in config_psa.h. Added
check_config_psa.h to visual studio project.

7fc75eac21 Enable all features in crypto_config.h
In order to pass existing tests like test_psa_crypto_config_basic
and test_psa_crypto_config_no_driver, all the new features need
to be enabled in the default crypto_config.h file. This change
enables those features by default and updates the other new
tests to compensate for everything being enabled by disabling
some features for some of the tests as needed.

0e00519711 Add feature support for RSA for PSA crypto config
In the original attempt to add RSA support to PSA crypto config was too
generic. This set of changes adds support for the following RSA features:
PSA_WANT_ALG_RSA_PKCS1V15_CRYPT, PSA_WANT_ALG_RSA_PKCS1V15_SIGN,
PSA_WANT_ALG_RSA_OAEP, PSA_WANT_ALG_RSA_PSS, PSA_WANT_KEY_TYPE_RSA_KEY_PAIR,
and PSA_WANT_KEY_TYPE_RSA_PUBLIC_KEY.

There were also some updates to ensure the proper inclusion of PSA crypto
library code when certain features are enabled. These updates were made to
address warnings and errors in builds from the new tests for these
features being added for PSA crypto configuration.

f4c4cb008c Added additional support for ECP for PSA_CRYPTO_CONFIG
The KEY_TYPE_ECC_KEY_PAIR and KEY_TYPE_ECC_PUBLIC_KEY were previously
being guarded by MBEDTLS_ECP_C in the PSA crypto library code. This change
moves it to the new MBEDTLS_PSA_BUILTIN_xxx and separates KEY_PAIR
and PUBLIC_KEY as needed. Tests have also been added to validate the new
settings.

d032195278 Phase 2 support for MBEDTLS_PSA_CRYPTO_CONFIG
This phase adds in support for the following features being
added to the list of features that can be configured in the
include/psa/crypto_config.h header file using the PSA_WANT_ALG_xxx
macros: ECDH, HMAC, HKDF, and RSA. These changes include changes to
the PSA crypto library to use the appropriate new guards that
will allow the feature to be compiled in or out either using
new PSA_WANT_ALG_xxx or the previous MBEDTLS_xxx macros.

For HKDF and HMAC, most of the PSA library code did not have a
specific matching MBEDTLS_xxx macro for that feature, but was instead
using the generic dependent MBEDTLS_MD_C macro. The ECDH and RSA
features more closely aligned with a direct replacement with a similar
macro.

The new tests for RSA, HMAC, and HKDF would normally unset additional
dependent macros, but when attempting to implement that level of
testing it required removal of too many core features like MD_C, PK_C,
ECP_C and other low level features. This may point to additional phases of
work to complete the transition of these features to the new model.

0ea39e0ee4 Correct use of MBEDTLS_PSA_BUILTIN_ALG_xxx in crypto library
The psa crypto library was generically using PSA_WANT_ALG_xxx, but
should have been using the correct MBEDTLS_PSA_BUILTIN_ALG_xxx
definition since that code is the builtin version. There were also
a couple of spots that needed to ensure the code block was enabled
for either ECDSA or DETERMINISTIC_ECDSA, not just one of them.

Fixed all the new ALG_ECDSA_DETERMINISTIC names to be
ALG_DETERMINISTIC_ECDSA instead.

Fixed test to use correct definitions.

7b453130e2 Updates to fix check-names and all.sh tests after review
Need to make sure the new MBEDTLS_PSA_ACCEL_XXX defines are not checked
since they should be defined by the PSA driver. Updated the list-macros.sh
script to modify the instances of those found to match the corresponding
MBEDTLS_PSA_BUILTIN_XXX that are defined in config_psa.h

Fixed definition of MBEDTLS_PSA_BUILTIN_ALG_ECDSA_DETERMINISTIC, name was
incorrect. Also fixed a missing space in the comments of crypto_config.h

c7c03b7d17 Enhanced documentation for crypto_config.h
Provided more detailed documentation for crypto_config.h file so it
is clear to users can enable cryptographic mechanisms using
PSA_WANT_XXX. If MBEDTLS_PSA_CRYPTO_CONFIG is not set the settings in
this file are not used.

Ensure that defines used in this file are set to 1 and not simply defined
per the specification. Also removed the __cplusplus guards since they are
not needed for this file.

2dfaf9ca23 Update how MBEDTLS_PSA_CRYPTO_CONFIG is handled
Originally, MBEDTLS_PSA_CRYPTO_CONFIG was being used to allow
inclusion of mbedlts/config_psa.h, but that needed to be updated
so that mbedtls/config_psa.h is always included and the definitions
specific to PSA configuration are now guarded by
MBEDTLS_PSA_CRYPTO_CONFIG. This will allow for the standard setup
to continue working while new PSA configuration items to also work.

6e33dbe9fd Created infrastructure for MBEDTLS_PSA_CRYPTO_CONFIG
In order to prepare for PSA cryptographic mechanism for conditional
inclusion of various modules, there needs to be some updates to
the mbedtls configuration to enable that feature to work. This initial
set of changes just lays the ground work and future changes will
implement the functional features.
