RZN1 Zephyr Support

Hello,

I have a RZN1D Eval Board, and I am trying to get Zephyr to run on it. I notice that currently the only RZN board currently supported officially in the main Zephyr project is RZN2L.

Question1: is there a RZN1D Eval Board board definition for Zephyr available with you that I can use? 

Question2: If I have to make my own Board Definition, what would be a good starting point? i.e. which existing board definition would be easy to copy and modify? RZN2L uses a different core, so it may not be a good starting point, I feel.

Thanks in advance your your help

Best Regards
