[SBC] Orange Pi Zero

I would like to add support for the Orange Pi Zero, and ideally some of the other Orange Pi's. I am planning to use Orange Pi Zero to run a workshop this year, and would ideally like to use gobot for it.

Some helpful links: Orange Pi Armbian - the best board image for Orange Pi boards

Armbian has an image with a newer kernel (4.x) for the Orange Pi, and I believe that sysfs access to GPIO works. I will check tommorow on one of my Orange Pi One boards.

Hi @jadr2ddude this post has the GPIO mappings for this board: https://kaspars.net/blog/linux/orange-pi-zero-gpio

Seems like adding it would not take long. Are you planning on working on this? :)

@deadprogram yes I will work on it. However I only have Orange Pi One at the moment. I will need to wait for it to be shipped before I can test Zero pin mappings.

This appears to provide the Orange Pi One mappings if you wanted to add that as well: https://cdn.instructables.com/FVP/79LM/INRJEEUJ/FVP79LMINRJEEUJ.LARGE.jpg

Hello, I'm willing to help for the Orange Pi One (H3 allwiner) I don't remember my source but here is a json of the mapping.

I feel like we could simplify this by just making a multipurpose struct for a SBC where we can just provide a mapping.

Hi @niaow I was thinking along the same lines. If we could change the implementation to a more generic one and just add the mappings with some unified structures - this would be nice. Do you have done some implementations in this direction?
