Overview
--------
The LS1046A Development System (QDS) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1046A
LayerScape Architecture processor. The LS1046AQDS provides SW development
platform for the Freescale LS1046A processor series, with a complete
debugging environment.
