* Allow the use of in-kernel config fragments instead of only pulling config fragments from the OE meta data. * The absolute path to the config fragment is used to allow pointing to different fragment locations. * Update the linux-ti-staging_3.12 recipe which uses config fragments to specify the absolute path Signed-off-by: Chase Maupin <Chase.Maupin@ti.com> Signed-off-by: Denys Dmytriyenko <denys@ti.com>
