+
+- SoC Overview:
+
+The LS1046A is a cost-effective, power-efficient, and highly integrated
+system-on-chip (SoC) design that extends the reach of the NXP value-performance
+line of QorIQ communications processors. Featuring power-efficient 64-bit
+Arm Cortex-A72 cores with ECC-protected L1 and L2 cache memories for high
+reliability, running up to 1.8 GHz.
+
+Details about LS1043A can be found at `ls1046a`_.
+
+- LS1046ARDB Board:
+
+The LS1046A reference design board (RDB) is a high-performance computing,
+evaluation, and development platform that supports the Layerscape LS1046A
+architecture processor. The LS1046ARDB board supports the Layerscape LS1046A
+processor and is optimized to support the DDR4 memory and a full complement
+of high-speed SerDes ports.
+
+Details about LS1043A RDB board can be found at `ls1046ardb`_.
+
+- LS1046AFRWY Board:
+
+The LS1046A Freeway board (FRWY) is a high-performance computing, evaluation,
+and development platform that supports the LS1046A architecture processor
+capable of support more than 32,000 CoreMark performance. The FRWY-LS1046A
+board supports the LS1046A processor, onboard DDR4 memory, multiple Gigabit
+Ethernet, USB3.0 and M2_Type_E interfaces for Wi-Fi, FRWY-LS1046A-AC includes
+the Wi-Fi card.
