Hello Otavio

Thanks for you replies.

I'm taking a time out to port my code to yocto master / 3.10.31 kernel,
to prepare u-boot recipe and to address issues discussed in the mail.

Yes, we work with Kontron on "official" BSP.

Hmm... could you provide a bit more details on this?
Does SPL stand for "secondary program loader"? How does this relate to
having single image for different hw configs?

Do you mean what is described here -
http://boundarydevices.com/configuring-i-mx6-machines-different-screens-nitrogen6x-sabre-lite/
?

I still do not understand how this correlates with configuring displays
in device tree (just overrides it? then, what for to have display
configuration in device tree at all?)...
