How to connect and control an external device at wandboard/other i.mx6q board

as stated above I would like to connect an external communication chip with 8bit interface to the i.mx6q.

1. Is it correct that the EIM interface would be the choice for this task ?

2. I have a wandboard-quad where at least a few EIM pins are routed to the board-to-board connector so possibly this could be done with a new interface board, but maybe there's a board which allows easier access, do you have a suggestion to that ?

3. there shall be running a linux on the board, so for that external device a new custom device and drivers have to be added to linux, where could I start reading about this, or is there maybe some example for such a task?


Thank you very much
