Subject: [PATCH 01/08] ARM: shmobile: Fix base address readout in headsmp-scu.S
Date: Mon, 18 Feb 2013 22:46:57 +0900 [thread overview]
Message-ID: <20130218134657.17303.35378.sendpatchset@w520> (raw)
In-Reply-To: <20130218134648.17303.97576.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Rework the early SCU setup code in headsmp-scu.S to read
the base address in the same way as we use to fetch the
address of the invalidation function.
Reported-by: Bastian Hecht <hechtb@gmail.com>

Tested on r8a7779. Feel free to add incrementally or fold into:
