Hi Patrick, If you are running your image embedded at some board, and have easy access to the board, you can plug it to network and make u-boot download kernel from your machine. So that deploy a new kernel becomes simple as copy the new kernel to the tftp folder, and rebooting target. This is also true for device-trees. And if you have NFS support is true for all userspace too. :)
