Explaining the NXP Yocto ecosystem

As we saw, Poky metadata starts with the meta, meta-poky, and meta-yocto-bsp layers, and it can be expanded by using more layers.

An index of the available OpenEmbedded layers that are compatible with the Yocto Project is maintained at http://layers.openembedded.org/.

An embedded product's development usually starts with hardware evaluation using a manufacturer's reference board design. Unless you are working with one of the reference boards already supported by Poky, you will need to extend Poky to support your hardware by adding extra BSP layers.
