Subject: [PATCH 14/14] csky: Add EM_CSKY_OLD 39
Date: Mon, 31 Dec 2018 23:33:04 +0800 [thread overview]
Message-ID: <1546270384-4590-12-git-send-email-guoren@kernel.org> (raw)
In-Reply-To: <1546270384-4590-1-git-send-email-guoren@kernel.org>
From: Guo Ren <ren_guo@c-sky.com>
C-SKY historically used 39, the same value as MCORE, from which the
architecture was derived.
C-SKY binutils support both EM_CSKY and EM_CSKY_OLD, confirmed by
binutils:include/elf/common.h
Signed-off-by: Guo Ren <ren_guo@c-sky.com>
