For building kernel or to get boot-yocto image:  
Download latest release according to your PC(I have used Linux ubuntu 16.04) of 64 bit.  
Unzip the file.you will get legato-spm tool.  
Run "legato-spm --install --module WP750X --update-link "  
Run “legato-spm --install --module WP750X --sdk pdk.64”  
there will be “legato.source.”  
Enter into that directory and give “make”(It will take \>1 Hr max).  
later create build environment for kernel configuration for that you need to use below commands:  
source poky/oe-init-build-env build\_bin  
. poky to get build\_env  
bitbake linux-yocto -c menuconfig  
bitbake -c linux-yocto compile  
Run Once again “make” to reflect the configurations changed in the flashing image.
