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.
