Hi Steve,
Try Documentation/powerpc/booting-without-of.txt in the Linux tree. You can find some device trees in arch/powerpc/boot/dts. You can get/clone the dtc compiler from git://www.jdl.com/software/dtc.git.
Cheers, Emil.

One question about the 8360 version. When I compile it straight up for the MPC8360EMDS_HOST_66 configuration, I never see any output at the startup of U-boot. But if I comment out the open firmware defines in the include/configs/MPC8360EMDS.h config file, then all works. Why doesn't this work for me straight up on the board it was compiled for? (This has been true for all U-boot versions I've tried for the
8360).
that's odd - MPC8360EMDS_HOST_66 works fine here and there's nothing obvious I can see in the code that would warrant that sort of behaviour. Can you provide details?
I think the problem is in his device tree. Either it's missing or incorrect.
I'm sure that you are right, Timur. Every version of U-boot I've tried to use, all the way back to 1.3.x, for the 8360 as well as the 8349EMDS, has had the same problem. And as soon as I comment out the OF stuff in the config file, all is well. (I haven't looked into it in detail, so I can't provide a lot of info at the moment. ......and my new custom MPC8358 board arrived just about an your ago! Friday afternoon, right on time! ;-) ).
At this point, I know *nothing* about device trees or OF...... Is this something that lives outside of u-boot?
I guess someone probably needs to point me to some "device trees for dummies" info........
