FPGA USB Bootloader - an open source IP for programming FPGAs without extra USB interface chips.

It implements a USB virtual serial port to SPI flash bridge on the FPGA fabric itself. For FPGAs that support loading multiple configurations it is possible for the bootloader to be completely unloaded from the FPGA before the user configuration is loaded in. From the host computer's perspective, the bootloader looks like a serial port.
