Probably.

I didn't want to create a lot of almost-equal files: the only
difference between the two boards is the .dtb to use. Hence I thought
of a script producing the config file from a template file.

But since there would be only 2 files for now it may be fine as well to
just have the two files.

I'll choose as soon as I start coding.
