Thanks for your helpful responses Scott and Ming Qian. Now, from reading the 
docco can you please verify my understanding is correct?- 

First, I need a basic DTS file which will give me a basic Device Tree. The 
cuboot*.c file takes care of adding other parameters to the Device Tree passed 
from u-boot via the old bd_info struct. 

Is this correct? If so, would it be possible to do away with the DTS file 
altogether? On the other hand, would it be possible to do away with the 
cuboot*.c file by providing a complete DTS file?
