[PATCH 2/2] ARM: exynos_defconfig: Enable s5p-secss driver

From: Krzysztof Kozlowski
Date: Wed Jan 06 2016 - 21:15:47 EST


The Exynos SoC provides a Security SubSystem block for accelerating some
cryptographic operations. Enable the driver for it - s5p-secss to
utilize the hardware acceleration.

Currently the s5p-secss driver supports AES in CBC and ECB modes.
However on Odroid XU4 (Exynos5422) and Trats2 (Exynos4412) boards this
change introduces one booting error:

alg: skcipher: encryption failed on chunk test 1 for ecb-aes-s5p: ret=22

The cbc-aes-s5p properly registers itself and passes self-tests.
