Bug #590: emulation/qemu-i440fx with GRUB payload: cbmem fails with `Table not found.`

* Author: Paul Menzel
* Status: New
* Priority: Normal
* Target version: none
* Start date: 2025-04-10
* Affected versions: 25.03
* Related links: In the GRUB command line, running GRUB’s `cbmemc`, it outputs the CBMEM console content. So, it seems to be overwritten later somehow.
----------------------------------------
See `emulation/qemu-i440fx/25.03-154-g9e757b3396/2025-04-10T04_35_41Z` in the board status repository for the configuration.

Building coreboot (25.03-154-g9e757b3396) for emulation/qemu-i440fx with GRUB (master) as payload, `cbmem` does not find the CBMEM tables and aborts with `Table not found.`.

    qemu-system-x86_64 -bios /dev/shm/coreboot/build/coreboot.rom -L /dev/shm -enable-kvm -smp cpus=2 -m 1G -hda /dev/shm/debian-32.img -serial stdio -net nic -net user,hostfwd=tcp::22222-:22

Using SeaBIOS, it works.
