From b668edaf8dcc8d09f6f1e71797422b44d4bd22a3 Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Sun, 12 Apr 2026 11:56:43 +0200 Subject: [PATCH] crypto: atmel-ecc - add support for atecc608b 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.
