How big is the spl now? For the OMAP4 spl, using '-ffunction-sections' and '--gc-sections' reduced the image size by 40% and helped it fit into the SRAM bugdet. I am sure your nand_spl is already fitting in the SRAM bugdet. But these flags may help reduce the size further. Do you want to try it?

Using gcc version 4.5.1 (Sourcery G++ Lite 2010.09-50) results in the same warnings and
Thanks, Dirk. I will fix these in the next version.
