That is what the elf loader does in a "normal" system. Grant did it on the PowerPC architecture - look at the archives, he didn't write new code for this, it's already in there. Here is the reversion back to the old way: <http://article.gmane.org/gmane.comp.boot-loaders.u-boot/33297> If you un-revert it (re-revert it?), you will have what Grant did. For some set of PowerPC platforms, it Just Works[tm]. For other architectures and platforms, start from this and make it work.
