                 Other methods exist to accomplish grouping and defining configuration options.

+                and then push the changes to the local bare clone of the kernel.
+                The result is that you directly add configuration options to the Yocto kernel 
                 <filename>meta</filename> branch for your BSP.
                 The configuration options will likely end up in that location anyway if the BSP gets 
                 added to the Yocto Project.

                 In general, however, the Yocto Project maintainers take care of moving the

                 Not only is it easier for BSP developers to not have to worry about putting those

                 'global' knowledge about the kinds of common configuration options multiple BSPs in
