Subject: [PATCH 01/03] ARM: shmobile: sh73a0: Introduce generic setup callback
Date: Thu, 04 Sep 2014 02:28:45 +0000 [thread overview]
Message-ID: <20140904022845.26216.45573.sendpatchset@w520> (raw)
From: Magnus Damm <damm+renesas@opensource.se>
Add a generic sh73a0 machine setup callback for the upcoming
sh73a0 multiplatform case. Cache needs to be configured, and
legacy clocks must be omitted.
Signed-off-by: Magnus Damm <damm+renesas@opensource.se>
