The first time virtio_init() gets called from board_init() PCI isn't ready. Thus any 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 --- The patch works for my but:
a) maybe virtio_init() should called only from board_init() the same way as on ARM?
b) can a repeated virtio_init() break already detected/initialized devices?
