I have the drivers working now. But there's a little problem left. When I try to use u-boot to update itself (write itself from RAM to Flash) it seems that it overwrites the out of band information too.
So when I try to reboot nothing is working because every program assumes that the first blocks are bad.
Do you have a suggestion how to fix that issue?

Thanks.
