When I followed them I ended up with a dead mpc3815e-rdb. I suspect my 
u-boot image was bad in some way, but my concern was that others would 
end up in the same situation following the instructions. Since the 
existing u-boot version was able to boot the linux-yocto kernel recipe, 
there appears to be no need to reflash u-boot.

Absolutely, this wasn't intended as a final "solution". The issue 
appears to be related to the 4.5.1 version of gcc failing in various 
ways to build either u-boot master or v2010.09, or v2010.12. I will 
report this to the u-boot mailing list just as soon as I can get back to it.
