I don't think we need to use C12A7328-F81F-11D2-BA4B-00A0C93EC93B with u-boot, since the partition being created is not an EFI system partition, for reference the pc gadget has this for ubuntu-seed because while ubuntu-seed is vfat, it is also the EFI system partition that gets booted off, i.e. ubuntu-seed has grub and shim and friends on it so it needs to be the EFI system partition type, but there is no such constraint on u-boot AFAICT unless somehow u-boot is being used with EFI somehow
