It seems that new kiwi does not support u-boot (non EFI/Grub2) images? Is there a solution/workaround? I have not ported plain u-boot support to the next generation kiwi, because of the effort to move all boards to efi boot. u-boot basically works as the EFI firmware being capable to load the grub efi module(s).

Yes, but not all boards are supporting EFI with U-Boot. Especially Arndale because "Samsung's bl1 lies at sector 1, overlapping with the EFI GPT, so we can not use EFI".

This is not true. For those boards, we can still use EFI, but need to convert to MBR. This is done in uboot-image-install.in in section "Convert GPT to MBR if necessary".

The only case I'm aware of where EFI is not a viable option is when we rely on U-Boot that is delivered with the system, but doesn't have efi_loader enablement. Apart from moonshot and midway I'm not aware of any such system still alive.

Is 32-bit Allwinner working with UEFI by now? Last time I tried it still fell apart and thus needed boot.scr.

Why does it fall apart? I‘m not aware of anything specific to Allwinner devices that would make it fail.

I didn't figure out and I haven't heard from anyone since. Probably missing memory reservations? IIRC my Cubietruck got into GRUB but had problems loading the kernel, hanging. Jetson TX1 was another case where UEFI was not working. It aborts and resets when loading GRUB. Dragonboard 410c was another such case I reported in the past. Theoretically they're all fixable, but right now there are a couple platforms where UEFI in U-Boot is not working.
