From b79848f225ac832ca0e973eb6cd7784bb6827f44 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 29 Apr 2022 15:34:44 +0200 Subject: crypto: fsl_hash: Remove unnecessary alignment check in caam_hash() While working on an LX2160 based board and updating to latest mainline I noticed problems using the HW accelerated hash functions on this platform, when trying to boot a FIT Kernel image. Here the resulting error message: Using 'conf-freescale_lx2160a.dtb' configuration Trying 'kernel-1' kernel subimage Verifying Hash Integrity ... sha256Error: Address arguments are not aligned CAAM was not setup properly or it is faulty error! Bad hash value for 'hash-1' hash node in 'kernel-1' image node Bad Data Hash ERROR: can't get kernel image! Testing and checking with Gaurav Jain from NXP has revealed, that this alignment check is not necessary here at all. So let's remove this check completely.
