Bug#873935: grub-coreboot: Explain use cases and what it does

[Julian Andres Klode]

Package: grub-coreboot
Version: 2.02-2
Severity: minor

I'm currently evaluating coreboot (reading a bit about it)
and came across this package and wonder what its purpose is.

I assume it is supposed to be chainloaded from an initial coreboot
payload, but since it's missing any instructions whatsoever, I can't
really figure out what it's doing.

I noticed it is creating a '/boot/grub/i386-coreboot/core.elf', so
I assume you could build like a FILO or grub2 coreboot image that
essentially chainloads a grub/i386-coreboot/core.elf binary from
a hard disk, but if you already have grub2 in the coreboot image,
it seems pointless to chainload into another one, so I really
can't see the usual use case here.
