Generally this is where certain people are pushing Embedded Linux to
go, but that doesn't mean it makes any sense to do so. UEFI requires a
lot of extra code and complexity, 100K+ in U-Boot alone, not to
mention GRUB, etc. It doesn't support embedded things like FPGA
images. FIT is a good solution and as an industry we should be
innovating on that, not forcing UEFI everywhere. If you need OS
selection, Boot Loader Specification (with FIT) is a good option.

Note that I write this not as someone opposed to EFI protocols (which
I have expended a lot of effort implementing and reviewing). Horses
for courses.
