Actually, I've already slipped this one in through the u-boot-fdt 
repository (I took the liberty since it was a problem with fdt.o and 
CONFIG_OF_LIBFDT).

<http://article.gmane.org/gmane.comp.boot-loaders.u-boot/39261/>

The problem is that only a couple of 8xx boards are using libfdt, but 
they were *all* compiling fdt.c.  The result for the boards that did not 
have CONFIG_OF_LIBFDT was the compilation warnings on the (erroneously 
compiled) fdt.c.

I had fixed it independently, but Jean-Christophe's fix was better (more 
complete), so I dropped my patch and picked up his.
