In the S3C2416 I don't need the mkimage stuff. I only need the raw SPL 
image padded at 8KB concatenated with the standard U-Boot. What I've 
done was to split the existing u-boot-ubl target in two; u-boot-ubl.bin, 
that I use to program the Flash, and u-boot-ubl that remains with the 
same functionality as before, just now it depends on u-boot-ubl.bin.
