Signed-off-by: Chanwoo Choi Acked-by: Kyungmin Park --- Arnd Bergmann suggested that need proper driver instead of static memory mapping. As Chanho Park reply[2], Sachin Kamat already posted the DT support patch[1] for memory mapping for SYSRAM. [1] http://www.spinics.net/lists/linux-samsung-soc/msg27647.html [2] https://lkml.org/lkml/2014/4/10/161 So, I'm going to re-implement following patch related to static memory mapping after merged Sachin Kamat patch[1].
