From 6e7b9f4fa0aed88051d6700afa510430b5d3fb69 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 5 Mar 2014 19:58:37 +0100 Subject: aes: Move the AES-128-CBC encryption function to common code Move the AES-128-CBC encryption function implemented in tegra20-common/crypto.c into lib/aes.c . This is well re-usable common code. Moreover, clean the code up a bit and fix the kerneldoc-style annotations.
