Rakesh, you probably want to take a look at the mkconfig script. It is responsible for doing much of the board configuration in preparation for building, including the generation of the top level config.mk that specifies things like ARCH, CPU and BOARD.

Hi Rakesh,
I am new to u-boot. I want to understand the flow of u-boot.
Here is a starting point for you: http://marc.info/?t=130381454100002&r=1&w=2
I did not understand that how board gets configured? in older version of u-boot i can see <board name>_config option in makefile, but in newer version it is not available in Makefile. So where it is?
boards.cfg has name ARCH, CPU based on this the makefile uses the respective sources and config. I don't know the actual mechanism in make - but i'am sure someone can answer this ;)
