From d9d0af98d75a76dc5da9bf70cfeb1fe2b06b0f22 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 2 Jul 2019 21:41:29 +0200 Subject: [PATCH] crypto: arm/aes-neonbs - switch to library version of key expansion routine Switch to the new AES library that also provides an implementation of the AES key expansion routine. This removes the dependency on the generic AES cipher, allowing it to be omitted entirely in the future.
