UBoot Performance issue in A13 MICRO

[iso9660]

I have noticed that when using last uboot in linux-sunxi repository the A13 MICRO has a performance regression.
I do usually test the board with guvcview for days. This evening I installed uboot following instructions bellow and noticed that the video was very slow comparing with uboot in Preliminary debian image at https://www.olimex.com/wiki/A13-OLinuXino-MICRO, so at last I decided to extract the uboot from the mentioned image to create my own images.
The slowdown can be also easily noticed when loading lxde desktop.
