Subject: [PATCH 1/9 v2] arm: introduce arm_add_mem_device to register dram device
Date: Mon,  1 Aug 2011 15:29:35 +0200	[thread overview]
Message-ID: <1312205383-13266-1-git-send-email-plagnioj@jcrosoft.com> (raw)
In-Reply-To: <20110801132643.GH6255@game.jcrosoft.org>

this will automaticaly register the device to armlinux_add_dram
