Configuring network booting for a development setup

Most professional i.MX6 boards will have an internal flash memory, and that would be the recommended way to boot firmware. The Wandboard is not really a product meant for professional use, so it does not have one, booting from a microSD card instead. But neither the internal flash nor the microSD card are ideal for development work, as any system change would involve a reprogramming of the firmware image.
