+ * When a PSA driver for ECDSA is present, it is now possible to disable
+ MBEDTLS_ECDSA_C in the build in order to save code size. For PK, X.509
+ and TLS to fully work, this requires MBEDTLS_USE_PSA_CRYPTO to be enabled.
+ Restartable/interruptible ECDSA operations in PK, X.509 and TLS are not
+ supported in those builds yet, as driver support for interruptible ECDSA
+ operations is not present yet.
