Now this is a problem. This breaks the backward compatibility with our X-Loader and we cannot just switch to 80100000...
And thinking back to when I was doing more OMAP3 conversions, there's no requirement to break compatibility with x-loader either. You just need to take care where you place things, see doc/SPL/README.omap3 for the SPL and X-Loader compatible setup.
