LEAF Kernel config

Hi Folks

What is the canonical way to modify kernel config files? I see there is
a number of cdiff files in the repo, also the same number of
architecture related config files. Now I am wondering where exactly the
modifications should go and why we are keeping all this redundant
information. I believe we either need the diff/cdiff files or the actual
hardware related config files, but both???

Thanks
