What I'm trying to get to is this: there's no working example (in the
shape of yocto BSP layer for instance) or evidence of anyone having
actually done it, ever. If you look at wic's bootimg-efi plugin, it
hardcodes vfat as partition type with no option for anything else. And
this is then used throughout meta-intel and meta-arm wks files, and
likely copied and tweaked into countless other layers. So it is not
exactly reassuring to hear 'but look at the zoo of filesystems that
u-boot supports'.

If I have a board in front of me (for instance, this Thinkpad X13
laptop from 2021 that I'm typing on right now), can I find out what it
can boot from? How?
