[U-Boot] L2 cache and LCD on sunxi

Hi,

I ran up a banana PI and noticed that HDMI works in U-Boot. Great!

Scrolling seems very slow though - is the L2 cache disabled perhaps?

Also are there instructions for getting an LCD running in U-Boot? I have an Olimex A20-OLinuxion-MICRO (what a mouthful!) with a 7 inch display if that matters. I can't find any useful information so far.

Regards, Simon
