Introduce a framework that allows loading the System Firmware (SYSFW) binary as well as the associated configuration data from an image tree blob named "sysfw.itb" from an FS-based MMC boot media or from an MMC RAW mode partition or sector. To simplify the handling of and loading from the different boot media we tap into the existing U-Boot SPL framework usually used for loading U-Boot by building on an earlier commit that exposes some of that functionality. Note that this initial implementation only supports FS and RAW-based eMMC/SD card boot. Signed-off-by: Andreas Dannenberg <dannenberg@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
