[PATCH v2 0/4] video: add support for QEMU ramfb

[Ahmad Fatoum]

QEMU's ramfb is a very simple Qemu fw_cfg protocol, where the guest
need only write a video settings structure to /etc/ramfb to get
DMA from the framebuffer working. Add a driver for this on top
of a newly added character device interface.
