+Overview
+--------
+The LS1046A Freeway Board (iFRWY) is a high-performance computing,
+evaluation, and development platform that supports the QorIQ LS1046A
+LayerScape Architecture processor. The FRWY-LS1046A provides SW development
+platform for the Freescale LS1046A processor series, with a complete
+debugging environment. The FRWY-LS1046A  is lead-free and RoHS-compliant.
