+Changes
+ * Cryptography and platform configuration options have been migrated
+ from the Mbed TLS library configuration file mbedtls_config.h to
+ crypto_config.h that will become the TF-PSA-Crypto configuration file,
+ see config-split.md for more information. The reference and test custom
+ configuration files respectively in configs/ and tests/configs/ have
+ been updated accordingly.
+ To migrate custom Mbed TLS configurations where
+ MBEDTLS_PSA_CRYPTO_CONFIG is disabled, you should first adapt them
+ to the PSA configuration scheme based on PSA_WANT_XXX symbols
+ (see psa-conditional-inclusion-c.md for more information).
+ To migrate custom Mbed TLS configurations where
+ MBEDTLS_PSA_CRYPTO_CONFIG is enabled, you should migrate the
+ cryptographic and platform configuration options from mbedtls_config.h
+ to crypto_config.h (see config-split.md for more information and configs/
+ for examples).
