Features
* When a PSA driver for ECDH is present, it is now possible to disable
MBEDTLS_ECDH_C in the build in order to save code size. For TLS 1.2
key exchanges based on ECDH(E) to work, this requires
MBEDTLS_USE_PSA_CRYPTO. Restartable/interruptible ECDHE operations in
TLS 1.2 (ECDHE-ECDSA key exchange) are not supported in those builds yet,
as PSA does not have an API for restartable ECDH yet.
* When all of ECDH, ECDSA and EC J-PAKE are either disabled or provided by
a driver, it is possible to disable MBEDTLS_ECP_C and still get support
for ECC keys and algorithms in PSA. See docs/driver-only-builds.txt.
