Build using manual steps

 * 1) 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.
 * 1) Clone basic Yocto layers:
 * 2) Switch to proper branches/commits
 * Another versions are not tested for compatibility.
 * Legacy BSP instruction can be found here R-Car Kingfisher Yocto Gen3 legacy
 * 1) Download proprietary driver modules to $WORK/proprietary folder
 * You should see the following files:
 * 1) Populate meta-renesas with proprietary software packages.
 * 2) Setup build environment
 * 3) Prepare default configuration files.
 * NOTE: extra configuration examples are available in the following directory:
 * 1) Add layer meta-rcar
 * 2) Start the build
 * 3) Building image can take up to a few hours depending on your host system performance. After the build has been completed successfully, you should see the output similar to:
 * and the command prompt should return.
 * 1) Bitbake has generated all the necessary files in ./tmp/deploy/images directory. You can verify its content:
 * Image is a Kernel image, *.dtb is a blob file, core-image--.tar.bz2 is the rootfs, modules-.tgz are kernel modules.
 * 1) You can now proceed with running Yocto images
