SPL uses the image header to detect the boot device and to find the offset of the next U-Boot stage. Since this information is stored differently in the eGON and TOC0 image headers, add code to find the correct value based on the image type currently in use. Series-changes: 2 - Moved SPL header signature checks out of sunxi_image.h - Refactored SPL header signature checks to use fewer casts Series-changes: 3 - Fixed offset of magic passed to memcmp - Refactored functions to not return pointers (fixes ambiguous NULL) Signed-off-by: Samuel Holland <samuel@sholland.org>
