+== Making Edits to Kernel Files and Rebuilding ==
+Typically this would be done via a patch in OpenWrt.
+
+However, it is possible to edit a kernel .c file in an existing build and then rebuild with the changes. 
+
+Example given below for Gateworks !OpenWrt 16.02
+ * Edit kernel file in build dir:
+{{{
+vi build_dir/target-arm_cortex-a9+neon_musl-1.1.12_eabi/linux-imx6/linux-4.4/drivers/net/usb/qmi_wwan.c 
+}}}
+ * Recompile kernel
+{{{
+make target/linux/compile
+}}}
+ * Push artifacts to !OpenWrt build system
+{{{
+make target/linux/install
+}}}
+ * Recompile !OpenWrt .ubi images (for Ventana NAND)
+{{{
+make -C gateworks/ imx6
+}}}
