Subject: [PATCH 02/14] arm64: big-endian: add big-endian support to top-level arch Makefile
Date: Fri, 11 Oct 2013 14:52:08 +0100 [thread overview]
Message-ID: <1381499540-28794-3-git-send-email-matthew.leach@arm.com> (raw)
In-Reply-To: <1381499540-28794-1-git-send-email-matthew.leach@arm.com>
From: Will Deacon <will.deacon@arm.com>
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.
