Hi, This patch set introduces Microchip / Atmel ECC driver.
The first patch adds some helpers that will be used by fallbacks to kpp software implementations. The second patch adds ECDH support for the ATECC508A (I2C) cryptographic engine. The I2C interface is designed to operate at a maximum clock speed of 1MHz. The device features hardware acceleration for the NIST standard P256 prime curve and supports the complete key life cycle from private key generation to ECDH key agreement. Random private key generation is supported internally within the device to ensure that the private key can never be known outside of the device. If the user wants to use its own private keys, the driver will fallback to the ecdh software implementation.
