The Mbed TLS implementations of ALG_TLS12_PRF, ALG_TLS12_PSK_TO_MS, ALG_HKDF, ALG_HKDF_EXTRACT, ALG_HKDF_EXPAND and ALG_PBKDF2 rely on HMAC operations through the driver interface. Thus if one of these algorithms is enabled and not accelerated, we need ALG_HMAC to be enabled (PSA_WANT_ALG_HMAC and PSA_WANT_KEY_TYPE_HMAC defined). As HMAC operations occur through the driver interface, HMAC operations can be accelerated even if the caller algorithm is not. Signed-off-by: Ronald Cron <ronald.cron@arm.com>
