note that the distro-bootcmd stuff should "just work" to avoid needing to do this step manually > however I see one error "Error to install/update FDT" while launch > ubuntu from grub menu. So, without editing grub.cfg to add 'devicetree' commands, it is expecting u-boot to load the correct fdt before 'bootefi'.. I have a patch[1] to do this as part of distro-bootcmd which we are using in fedora.

I think also CONFIG_DISTRO_DEFAULTS.. assuming there are no special hacks in ubuntu's grub build for arm/arm64, at least. For fedora we are not using any special arm specific patches for grub (or shim/fallback) and (at least with the addition of the patch mentioned above to handled fdt loading in u-boot) it all just works automatically the same way it does on x86_64 (with all the other patches that landed for 2017.11 so far).
