It not make sense to load our firmware to the ZTEX boards, because we would loose the ability to load the FPGA bitstream. Also we don't want to include this in our firmware. Finally, we want to support the default ZTEX firmware. Hence, this drafts one possibility to allow for different firmware interfaces. The differences between interfaces are: * How GPIO pins are accessed * Which endpoints are used for the FIFOs If we anticipate only ZTEX and our firmware, I would suggest we explore adopting the ZTEX interface. Else this is maybe a direction we want to go.

Not a PR, but just a plain draft so far. |

approach looks good to me. Let's have a detailled review once the ZTEX firmware is ready and we know that the abstraction actually covers all cases we want to have covered. |
