Yeah, but if we're shoving a lot of hardware-specific ACPI table
generation into the guest's firmware, instead of just doing it on the
qemu side where a number of us seem to think it belongs, then there *is*
a benefit to using Coreboot. When stuff changes on the qemu side and we
have to update the table generation to match, you end up having to
update just the Coreboot package, and *not* having to patch both SeaBIOS
The extra package in the distro really isn't painful to handle, and I
suspect it would end up *reducing* the amount of work that we have to do
to update. You update *just* Coreboot, not *both* of SeaBIOS and OVMF.

That has been said, and it's been said for the FAT implementation in the
kernel too. If a distribution is happy to ship the kernel without
ripping out its FAT support, then I see no reason why that distribution
wouldn't also be happy to ship a version of OVMF with a clean
implementation of FAT support. It doesn't make sense to be happy with
one but not the other.

That'll get merged soon. We are working on the corresponding spec

Ooh, shiny. Yeah, when I get back to actually working on it rather than
just heckling, I'll make sure I do :)
