+New deprecations
+ * PSA_WANT_KEY_TYPE_xxx_KEY_PAIR and
+ MBEDTLS_PSA_ACCEL_KEY_TYPE_xxx_KEY_PAIR, where xxx is either ECC or RSA,
+ are now being deprecated in favor of PSA_WANT_KEY_TYPE_xxx_KEY_PAIR_yyy and
+ MBEDTLS_PSA_ACCEL_KEY_TYPE_xxx_KEY_PAIR_yyy. Here yyy can be: USE, IMPORT,
+ EXPORT, GENERATE, DERIVE. The goal is to have a finer detail about the
+ capabilities of the PSA side for either key.

+Features
+ * New symbols PSA_WANT_KEY_TYPE_xxx_KEY_PAIR_yyy and
+ MBEDTLS_PSA_ACCEL_KEY_TYPE_xxx_KEY_PAIR_yyy (where xxx is either ECC, RSA
+ or DH) were introduced in order to have finer accuracy in defining the
+ PSA capabilities for each key. These capabilities, named yyy above, can be
+ any of: USE, IMPORT, EXPORT, GENERATE, DERIVE.
