I was annoyed with Allwinner and deleted the design I was working on. Also,
I think they restricted the RGBTTL output to 1280x800 and EOMA68 requires
1366x768 minimum.

After using a superb LCD driver under Mr Ding's design direction the other
Business Units started to license some shoddy LCD driver that restricted
the framebuffer to 1MByte in size.

Any product that went beyond that *also licensed PowerVR* and there's no
way in hell I'm doing a Card with a PowerVR GPU.

All that having been said, it turns out yet again that it is Allwinner
Marketing Dept lying and incompetence that shoots themselves in the foot.

They started lying about the A20 a few years back, saying it is only
capable of 1024x768 because otherwise it made other offerings, more
"advanced", on the same marketing page, look bad.

http://linux-sunxi.org/A64 says the A64 can do up to 1920x1080p60 on the
RGBTTL interface.
