[meta-freescale] /dev/fb0 missing with nitrogen6x and latest Yocto&meta-fsl-arm master

[Carlos Rafael Giani]

Hello,

I just built an image for the nitrogen6x with poky, meta-openembedded, 
meta-fsl-arm, meta-fsl-arm-extra, meta-fsl-demos all at the latest 
master. boundary-kernel version is 4.1.15.

Looking at /dev/ shows that there is no /dev/fb0, fb1, or any fbX device 
node!

I did not add any arguments to the kernel command line. I built the 
core-image-x11 image. I also tried to add a uEnv.txt file to the boot 
partition, but it didn't help:

     bootargs=video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 
video=mxcfb1:dev=hdmi,1280x720M at 60,if=RGB24 console=ttymxc1,115200 
vmalloc=400M consoleblank=0 rootwait fixrtc root=/dev/mmcblk0p2

Any ideas what is going on? I attached the dmesg log.
