There will be virtually no change in the driver - all required stuff is already there. See the STE UX500 variant - they did exactly the same, enlarged the FIFO. One of the main reason I've immediately abandoned the idea of using FIQ was the need of changing the driver for no good reason.

Totally agree. The thing is that you are the only person right now who doesn't have any problems. The others can quickly benefit from the workaround. I think I made the status of this patch clear enough - let me quote myself: "HACK HACK HACK" ;-)

If we succeed with this, you (and all other users) will get the "improved" FPGA image. But for VE only indeed.
