Raw Blame History

 SoCFPGA EPCS/EPCQx1 mini howto:
 - Instantiate EPCS/EPCQx1 Serial flash controller in QSys and rebuild
 - The controller base address is the "Base" in QSys + 0x400
 - Set MSEL[4:0]=10010 (AS Standard)
 - Load the bitstream into FPGA, enable bridges
 - Only then will the driver work
