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.

a TQM860, but this is just an unimportant detail):

You fail to pass the device tree - which is essential.
And device tree support is not present in your old version of U-Boot.

Seems your documentation is a couple of years out of date.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