During Secure Boot, a bootscript is validated using its header. This patch copies both these images to DDR from NOR and then validates and executed them from DDR. (If NOR is the boot source for LS2080).
This copy step is done to make this step common across booting sources. Because in case of non-xip memories (e.g. NAND, SD) it is neccessary to copy both these images to DDR.
For other ARM Platforms (ls1043 and ls1020), header is not copied from NOR to DDR (otherwise customers will need to modify the existing headers).
