If anyone has any objections, please let me know. ------------------ From: Thorsten Blum [ Upstream commit b668edaf8dcc8d09f6f1e71797422b44d4bd22a3 ] Tested on hardware with an ATECC608B at 0x60. The device binds successfully, passes the driver's sanity check, and registers the ecdh-nist-p256 KPP algorithm. The hardware ECDH path was also exercised using a minimal KPP test module, covering private key generation, public key derivation, and shared secret computation.
