Use SPI flash to boot the NB3000XN/AL with a combined image

The NanoBoard 3000XN and AL provide a number of options for auto-configuring the onboard FPGA:
The SPI Flash memory inside the Spartan 3AN (NB3000XN board only).
The two SPI Flash devices on the NanoBoard itself – the Embedded Flash and the Boot Flash.
There’s also a handy utility included in the Altium reference designs that makes it easy to create a combined hardware/firmware boot code, which can be applied to whichever Flash memory you use.
