Subject: [PATCH 1/2] ARM: shmobile: Move shmobile_scu_base from .text to .data
Date: Thu, 28 Jan 2016 16:04:21 +0100 [thread overview]
Message-ID: <1453993462-12210-2-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1453993462-12210-1-git-send-email-geert+renesas@glider.be>
shmobile_scu_base is being written to, so it doesn't belong in the .text
section. Fix this by moving it from asm .text to C .data, as it's no
longer used from asm code since commit 4f6da36f7edd5790 ("ARM: shmobile:
Remove old SCU boot code").
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
