                 One thing missing in this particular BSP, which you will typically need when 
                 developing a BSP, is the kernel configuration file (<filename>.config</filename>) for your BSP.
                 When developing a BSP, you probably have a kernel configuration file or a set of kernel
                 configuration files that, when taken together, define the kernel configuration for your BSP.
                 You can accomplish this definition by putting the configurations in a file or a set of files 
-                inside a directory located at the same level as your append file and having the same name 
-                as the kernel.
