From 5ce26f3b5ae8fafdd28375a004f7b8e924e9bacb Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Sun, 15 Sep 2013 17:10:43 +0200 Subject: [PATCH] ARM: move AES typedefs and function prototypes to separate header Put the struct definitions for AES keys and the asm function prototypes in a separate header and export the asm functions from the module. This allows other drivers to use them directly.
