From 00568b8a6364e15009b345b462e927e0b9fc2bb9 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Thu, 21 Oct 2021 10:26:57 +0100 Subject: ARM: 9148/1: handle CONFIG_CPU_ENDIAN_BE32 in arch/arm/kernel/head.S MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit My intel-ixp42x-welltech-epbx100 no longer boot since 4.14. This is due to commit 463dbba4d189 ("ARM: 9104/2: Fix Keystone 2 kernel mapping regression") which forgot to handle CONFIG_CPU_ENDIAN_BE32 as possible BE config.
