give me some advice
Well, obviously you have a problem with the dfitions for your CPU in some of the header files. As I don't know your code (and I don't review any out-of-tree repositories) I can just say that you should fix your header files. As a quick and dirty workaound you could also disable KGDB support in your board configuration unless you really need it.
