Calculate the SDRAM size from DMM configuration registers instead of using hard-coded values. This gives correct values for all different boards. It's assumed that DMM sections do not overlap memory areas. Signed-off-by: Aneesh V <aneesh@ti.com> Tested-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
