ok, thanks - I will then apply Fabio's patches for the Freescale's boards.

I think also that using the environment seems a clumsy solution. We used
a lot of times in the past, and we have not unified their usage.

I admit that using DT also for u-boot seems a better solution. You're
right about i.MX6 in kernel, but on the other hand I like how it is
described for i.MX28 boards. The display-timings node contain all
information we need. It would be nice to have the same for i.MX6.

Best regards,
Stefano
