Hello Fabio,
I work with Steve. There is really nothing in the boot log. U-boot runs fine and loads the kernel, decompresses it and displays message "Starting kernel" and we don't see any console output.
However when using 2.6.35 kernel and associated freescale patches, using the same u-boot and kernel command line parameters board boots just fine.
We have noticed that there have been lot changes between 2.6.35 and the latest 3.1.0 RC available from ARM git and also 3.0 git source from pentronix git.
Particularly stuff in arch/arm/mx28, mx23 seems to have been consolidated into arch/arm/mach-mxs
