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?
Yes.
If so, would it be possible to do away with the DTS file altogether?
How, other than by encoding all the information about the board in code rather than data, which would be a step backwards?
On the other hand, would it be possible to do away with the cuboot*.c file by providing a complete DTS file?
Yes, though that eliminates the ability to dynamically set certain parameters from the firmware. Better is to use an up-to-date u-boot, and have u-boot fill in the dynamic fields (MAC address, clocks, command line, etc) directly.
