Hi Shantur
[...]
Also the information is very limited, e.g. it does not show the Ubuntu version, kernel version, etc.
The length of the labels is only limited by available storage. It is the OS'es choice to opt for a such a short label.
Yes, really I am looking for metadata that includes more detail at different leaves, not just a label.
The job of these EFI is to load grub bootloader and rest all details (kernel version, OS, etc) is supposed to be handled by Grub.
Not necessarily. I'd prefer skipping GRUB for embedded boards that don't boot distros. You can load the kernel directly and u-boot allows to configure that (see eficonfig and efidebug). WE just need to make sure that a bootflow with grub works as intended
