> you'd have to write some code that uploads the FPGA image and then burns it into the EPCS.

You might want to take a look at u-boot. You can upload using kermit, y/z modem, tftp, nfs, etc.

Then program the epcs using u-boot's epcs programming utilities. Even if u-boot isn't appropriate

for your application, you may still find some of its code useful.
