The yocto-bsp, yocto-kernel and yocto-layer scripts have just been removed from master (for the sumo/2.5 release) and thus we'll need to remove references to these from the documentation. For yocto-layer we have a replacement in the form of bitbake-layers (specifically the create-layer subcommand), however for the others I suspect we'll have to come up with alternative instructions to perform the same actions.
