From a8a752c084031905940129f8a6ba303925e0fac9 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 5 Mar 2014 19:59:52 +0100 Subject: env: Implement support for AES encryption into fw_* tools Implement support for encrypting/decrypting the environment block into the tools/env/fw_* tools. The cipher used is AES 128 CBC and the implementation depends solely on components internal to U-Boot. To allow building against the internal AES library, the library did need minor adjustments to not include U-Boot's headers which are not wanted to be included and define missing types.
