Build Yocto image
 Create a directory and switch to it Warning! Yocto builds require a lot of disk space (up to 100 GB). Make sure you have got enough before starting the build. mkdir build cd build export WORK=`pwd`  Clone basic Yocto layers: cd $WORK git clone git://git.yoctoproject.org/poky git clone git://git.openembedded.org/meta-openembedded git clone git://git.linaro.org/openembedded/meta-linaro.git git clone git://github.com/renesas-rcar/meta-renesas git clone git://github.com/CogentEmbedded/meta-rcar.git
