This ROM will be started by QEMU and will load the firmware.
The firware will be based on Petit Boot, the aim of the bootstrap
"firmware"
is to ask QEMU to load the kernel and initramfs to the RAM.
It also builds the bootinfo structure to pass to the kernel the
same way QEMU does when it loads directly the kernel.
To build the bootstrap:
$ git submodule init roms/m68k-virt
$ git submodule updage roms/m68k-virt
"update"
You can combine as "update --init".
$ make -C roms m68k-virt-bootrom

We'll need to mirror that on gitlab.
Otherwise LGTM.
