Update image
------------
After the build finished, there will be an update image called
u-boot.update. This can either be used in the DFU mode (which isn't
supported yet) or encapsulated in an EFI UpdateCapsule.
To build the capsule use the following command
$ tools/mkeficapsule -f u-boot.update -i 1 UpdateUboot
Afterward you can copy this file to your ESP into the /EFI/UpdateCapsule/
folder. On the next EFI boot this will automatically update your
bootloader.
