Right - of course I want to build a working (diving;-) U-boot.
Because I didn't get any output with my own image, 
I started to attach the debugger...

My problem here is, that I have a working U-boot binary
without the sources *and* some sources that dont build
a working U-boot :(
It would be helpfull to send me your image. Once it works
here I will ask you for the sources :)
