+Overview
+--------
+QorIQ LS1012A FREEDOM (LS1012AFRDM) is a high-performance development
+platform, with a complete debugging environment. The LS1012AFRDM board
+supports the QorIQ LS1012A processor and is optimized to support the
+high-bandwidth DDR3L memory and a full complement of high-speed SerDes ports.
+
+LS1012A SoC Overview
