      1 Overview
      2 --------
      3 QorIQ LS1012A FREEDOM (LS1012AFRDM) is a high-performance development
      4 platform, with a complete debugging environment. The LS1012AFRDM board
      5 supports the QorIQ LS1012A processor and is optimized to support the
      6 high-bandwidth DDR3L memory and a full complement of high-speed SerDes ports.
