Let's leave ENV out of this discussion. Moreover, this needs to be done in 
proper incremental steps.

Furthermore, new thread should be started.

Just an idea, to avoid undef in board-files, we can have #ifdef CONFIG... 
#define CONFIG... #endif constructions in the CPU-specific files. This will 
allow simple overriding (of course, these files would have to be included at the 
bottom of the board config file then).

Otavio, any plans to finish u-boot/mx23 soon?
