A QuickBoot method for FPGA design remote update application note (PDF!) from Xilinx:
This application note presents detailed descriptions of the QuickBoot method that are important for evaluating the QuickBoot solution and debugging implementation problems. Demonstration implementations of the QuickBoot method are provided for the KC705 evaluation board using the serial peripheral interface (SPI) flash or byte-wide peripheral interface (BPI) flash. See KC705 Board Demonstrations, page 33 to run the QuickBoot demonstrations on the KC705 evaluation board.
