Has anyone flashed a more functional version of U-Boot to their Edison? Where are the Edison-specific changes to the U-Boot source code? U-Boot is GPL, so they must be made freely available.
Try with this one: https://github.com/01org/edison-u-boot/tree/master/arch/x86 edison-u-boot/arch/x86 at master · 01org/edison-u-boot · GitHub
Instead of using /boards/intel go to /arch/x86
