Subject: [PATCH 07/08] ARM: shmobile: EMEV2 map_io update
Date: Tue, 02 Jul 2013 18:28:22 +0900 [thread overview]
Message-ID: <20130702092822.32066.80242.sendpatchset@w520> (raw)
In-Reply-To: <20130702092725.32066.54861.sendpatchset@w520>
From: Magnus Damm <damm@opensource.se>
Update the EMEV2 struct map_desc to exclude the SMU
and also include the ->map_io() callback in the DT
version of EMEV2 board support.
The EMEV2 SMP code can these days perform ioremap()
early on without the SMU information in the io_desc[].
To correctly support SMP in case of DT-only board
support then the ->map_io() callback is needed.
