* That section tries to look funny. U-Boot is serious stuff.
* The information is outdated. BDI3000 is not on sale, 
https://www.denx.de/wiki/bin/view/DULG/Manual is no longer maintained.
* It contains advice that we would prefer not to give like
   email("Hi, I am new to U-Boot, how do I get started?")
* It is incomplete. You cannot introduce a new board without defconfig.

An introduction chapter for new developers in doc/develop/ would be helpful.

Best regards

Heinrich
