Thanks for CCing me, I assume this is a driver for that "altera_epcq_controller"
which you can synthesise into your FPGA, is that correct? Is there an Hard IP 
variant of this controller in the public or is this purely Soft IP?

Also, I cannot find any documentation for this IP block even if I search through 
Quartus/QSys, is there any proper documentation available anywhere?
