[oe] Howto get Video Framebuufer working

[Bernard Mentink]

Hi Guys,

Can anyone give me a helping hand getting graphics/framebuffer working on a new i.mx31 platform.

I have configured everything I can think of that is required in the kernel (see relevent section below) and the i.mx31 viddeo driver is definetely getting built. (See the object files below)

However, I do not see any /dev/fb0 device .... What do I need to do to get one going?

Cheers,
Bernie.
