Sorry. No. I don't have any socfpga platform to be able to test it. I believe Alan will test it.

If we end up with any reasonable solution which will suitable for all of us I have no problem to add you here because every change in this subsystem should be validated by all parties. You should be definitely in a CC for all these emails which will be ensured by adding your names here.
But still there will be just one repo which will store patches for this subsystem.

It is just for adding fpga end driver here. I have here zynq devcfg driver. It is just preparation for others end driver.
