+Overview
+--------
+The LS1043A Reference Design Board (RDB) is a high-performance computing,
+evaluation, and development platform that supports the QorIQ LS1043A
+LayerScape Architecture processor. The LS1043ARDB provides SW development
+platform for the Freescale LS1043A processor series, with a complete
+debugging environment. The LS1043A RDB is lead-free and RoHS-compliant.
