Based on the patch by Takanari Hayama <taki@igel.co.jp> Adds support framework necessary to use Media RAM (MERAM) caching functionality with the LCDC. The MERAM is accessed through up to 4 Interconnect Buffers (ICBs). ICB numbers and MERAM address ranges to use are specified in by filling in the .meram_cfg member of the LCDC platform data Signed-off-by: Damian Hobson-Garcia <dhobsong@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
