 Poky is a reference distribution of the Yocto Project. It is a great starting point to build your own custom distribution as it contains both the build system and the the baseline functional distribution. Along with containing recipes for real target boards, it also contains the recipes for building the image, for example 64-bit Arm machines supported in QEMU. The example 64-bit machine emulated by QEMU does not emulate any particular board but is a great starting point to learn and try the basics of running this distribution.
