A layer is really just a location or area in which you place the recipes for your BSP.

<note>The Yocto Project supports four BSPs that are part of the
Yocto Project release: <filename>atom-pc</filename>, <filename>beagleboard</filename>,
<filename>mpc8315e</filename>, and <filename>routerstationpro</filename>.
The recipes and configurations for these four BSPs are located and dispersed
within the local Yocto Project files.
Consequently, they are not totally isolated in the spirit of layers unless you think
of <filename>meta-yocto</filename> as a layer itself.

On the other hand, BSP layers for Crown Bay, Emenlow, Jasper Forest,
N450, and Sugar Bay are isolated.</note>
N450, Cedar Trail, Fish River, Fish River Island II, Romley, sys940x, tlk,

<para>When you set up a layer for a new BSP, you should follow a standard layout.
