Can you elaborate on what you're setting here? This seems like a potentially neat trick that should be documented.

It just enabling efidebug command to be able to setup efi variables. We have discussed it recently with Ilias in connection to efi boot without grub. I think Ilias is the best person to talk about details based on patches he is sending.
Thanks, Michal

It is documented, just not pushed yet u-boot/next, due to the file renaming on the documentation. You can find details here https://lists.denx.de/pipermail/u-boot/2021-March/444855.html but the tl;dr version is that , with newer kernels we can add the initrd path of the specific image in an EFI Boot### variable.
That allows you to boot EFI based vertical distros, that contain multiple initrd-kernel pairs, by just using the EFI interfaces and not have to rely on GRUB or whatever people were doing up to now.
Cheers /Ilias
Thanks, Michal
