[PATCH 2/2] crypto: atmel-ecc - add support for atecc608a

[Thorsten Blum <blum@kernel.org>]

The driver already supports the ATECC508A and ATECC608B and uses only
commands shared by these devices.

Microchip documents the ATECC608B as a backwards-compatible, functional
drop-in replacement for the ATECC608A, with the same device structure
and command interface [1]. Therefore, add support for the ATECC608A.

ATECC608A hardware was not available for testing.
