The GUID is generated at runtime based on the devicetree compatible
string and the fw_image name.
(https://docs.u-boot.org/en/latest/develop/uefi/uefi.html#dynamic-firmware-update-guids)

So this means each board should get a unique GUID, based on the
compatible, and in addition, based on which storage device it is
booted from, as the fw_image name is different depending on the
boot device.
