+Overview
+--------
+The LS2085A Development System (QDS) is a high-performance computing,
+evaluation, and development platform that supports the QorIQ LS2085A
+Layerscape Architecture processor. The LS2085AQDS provides validation and
+SW development platform for the Freescale LS2085A processor series, with
+a complete debugging environment.
+
+LS2085A SoC Overview
