What you say boils down to: Please help me, but don't mention the solution, because I'm not going to do that. In short, it's stupid. You are wasting your time, and ours. In the first step, please update your U-Boot. 0.4.0 has no support for device tree.

Seems your documentation is a couple of years out of date. Please update.
