=====Building Yocto BSP images including the U-Boot, the Linux kernel, and the target root file system=====
As known, Linux needs a root file system to operate: a root file system must contain everything needed to support the Linux system (applications, settings, data, etc.). The root file system is the file system that is contained on the same partition on which the root directory is located. The Linux kernel, at the end of its startup stage, mounts the root file system on the configured root device and finally launches the <code>/sbin/init</code>, the first user space process and "father" of all the other processes.
