[coreboot] coreboot qemu q35 grub hang

[John Fastabend]

Hi,

I'm trying to get coreboot working with QEMU x86 q36/ich9 but it
is hanging at grub prompt. With coreboot compiled for i440fx/pii4 and '-M pc'
on the qemu command this works fine. Also native SeaBIOS works with
q35 option no problem.

So I'm wondering if anyone has this working. Maybe I'm just missing
some option somewhere? This is on latest git repository and I was sure
this worked at some point (I rolled back to last year and it was still
hanging) but I haven't tried to bisect it yet.

This is my qemu command,

# qemu-system-x86_64 -bios ./coreboot.rom \
   -hda /var/lib/libvirt/images/Fedora-test0.img \
   -M q35 -m 8G  -enable-kvm -smp 1 \
   -chardev file,id=debugcon,path=/tmp/bios.log \
   -device isa-debugcon,iobase=0x402,chardev=debugcon

Here is my config.
