From a0974e6e217aead196033d72f898e2acb575304d Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 11 Oct 2013 14:52:08 +0100 Subject: [PATCH] arm64: big-endian: add big-endian support to top-level arch Makefile This patch adds big-endian support to the AArch64 top-level Makefile. This currently just passes the relevant flags to the toolchain and is predicated on a Kconfig option that will be introduced later on.
