+* \brief
+* Provides variables necessary to inform programming tools how to program the
+* attached serial flash memory. The variables used here must be placed at
+* specific locations in order to be detected and used by programming tools
+* to know that there is an attached memory and its characteristics. Uses the
+* configuration provided as part of BSP.
