[Arm-netbook] 480 × 272 5" LCD lash up ready for testing

[joem]

Been busy in other areas.
The furthest I got was to note that some driver thing not done up - and may be intimately tied to VGA drivers.
It loads without error messages now and something happens on the video - though nowhere near interesting.
I order 2xcubie breakout boards and try wiring up those as back up.
If the cubie2 can do it, it can be ported to eoma in no time.
Olimex guys have LCD working, but there is not ONE complete working example
that cuts the chase to show anyone how its done for RGB LCD for A10 or A20.

Thanks for the settings, I will give it a go soon.
