When virtio_init() gets called from board_init() PCI isn't ready. Thus, virtio-over-PCI (e.g. network interfaces) devices can't be detected and used without additional `virtio scan` scan in the shell or a script.
Signed-off-by: Łukasz Stelmach l.stelmach@samsung.com --- Changes since v1: - remove virtio_init() call from board_init() - select BOARD_LATE_INIT for TARGET_QEMU_VIRT
