Is this 'virt' machine not the _real_ > Qemu > virt ARM32? virt is a generic virtual platform and doesn't resemble any real hardware. This is nice for some use-cases, as it doesn't have the restrictions of real hardware systems, but then most of the peripherals are virtio or mapped on a virtual PCI bus. Barebox is lacking driver support for most of those peripherals, so the usefulness of this machine is limited when used with Barebox.
