OMAP SRAM can be used as video memory on OMAP1 and 2. However, there usually is very little SRAM available, thus limiting its use, and no board supported by the kernel currently uses it. This patch removes the use of SRAM as video ram for the omapdss driver to simplify memory handling. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
