I followed the documentation mentioned at https://community.nxp.com/thread/333571. As mentioned there I inserted two layers as meta-fsl-arm & meta-fsl-arm-extra. There yocto building is done successfully but at booting time it is giving System Halted massage after kernel boot. Please get the total kernel logs below.
