Dear Fabio Estevam,

> RPC: Registered tcp transport module.
> RPC: Registered tcp NFSv4.1 backchannel transport module.
> Bus freq driver module loaded
> IMX usb wakeup probe
> usb h1 wakeup device is registered
> mxs_cpu_init: cpufreq init finished

> Loading the same kernel using the bootlets from the

> Comparing the DDR2 initialization from the bootlets code against the U-boot

> Also tested with 'mtest' command, which runs succesfully.
