Not much too share, I'm using:
https://github.com/Freescale/fsl-community-bsp-platform
(master at the moment, I'm not sure if the imx6 GPU-drivers landed in danny, 
yet)

The only thing I've done within yocto is to removed x11 from DISTRO_FEATURES
(I've edited poky/meta/conf/distro/include/default-distrovars.inc, I'm pretty 
sure their is a proper way of doing this!)


The image file I'm last played with looked like this:

"
require core-image-base.bb

IMAGE_FEATURES += "ssh-server-openssh"
IMAGE_INSTALL += "strace gpu-viv-bin-mx6q gdb rsync libpng libpng12 git tslib"

DEPENDS = "gpu-viv-bin-mx6q libpng"
"

(Their was a reason why I've added stuff in IMAGE_INSTALL and DEPENDS .. but I 
don't recall the reason)


After the image is built, I'm using the generated sysroot and toolchain to 
build Qt (outside of yocto).

Their is a meta-qt5 repo as well, I heard it's not 100% done yet.
I haven't used it yet.
