This patch allows configuration of the eNET board for generation of a U-Boot image which can be loaded into RAM (using tftp for example). Executing the image loaded into RAM is very similar to a cold-boot (the image is relocated to upper memory etc). This allows very rapid development and testing of new features without needing to burn Boot-ROMs
