It might be worth asking your electronics people whether they're going to use the Xilinx SysACE chip in your hardware design. If this is the case then you can program the Virtex and load in the kernel and bootloader from Compact Flash. I don't know whether uboot supports this out of the box since I wrote my own Virtex II bootloader, but it should be quite doable. Certainly you really want to avoid PROMs in the design if at all possible - with our design it's possible for us to swap out a CF and in one step replace all hardware and software, upgrading is a case of sending the customer a loopback mountable filesystem which reloads the CF after the customer downloads the "firmware update" via a web page.
