3The LS1046A Reference Design Board (RDB) is a high-performance computing,
4evaluation, and development platform that supports the QorIQ LS1046A
5LayerScape Architecture processor. The LS1046ARDB provides SW development
6platform for the Freescale LS1046A processor series, with a complete
7debugging environment. The LS1046A RDB is lead-free and RoHS-compliant.
