+Overview
+--------
+The LS1021ATWR is a Freescale reference board that hosts the LS1021A SoC.
+
+LS1021A SoC Overview
+------------------
+The QorIQ LS1 family, which includes the LS1021A communications processor,
+is built on Layerscape architecture, the industry's first software-aware,
+core-agnostic networking architecture to offer unprecedented efficiency
+and scale.
+
+A member of the value-performance tier, the QorIQ LS1021A processor provides
+extensive integration and power efficiency for fanless, small form factor
+enterprise networking applications. Incorporating dual ARM Cortex-A7 cores
+running up to 1.0 GHz, the LS1021A processor delivers pre-silicon CoreMark
+performance of over 6,000, as well as virtualization support, advanced
+security features and the broadest array of high-speed interconnects and
+optimized peripheral features ever offered in a sub-3 W processor.
+
+The QorIQ LS1021A processor features an integrated LCD controller,
+CAN controller for implementing industrial protocols, DDR3L/4 running
+up to 1600 MHz, integrated security engine and QUICC Engine, and ECC
+protection on both L1 and L2 caches. The LS1021A processor is pin- and
+software-compatible with the QorIQ LS1020A and LS1022A processors.

+ - Two PCI Express Gen2 controllers running at up to 5 GHz
+ - One Serial ATA 3.0 supporting 6 GT/s operation
+ - Two SGMII interfaces supporting 1000 Mbps
+ - Additional peripheral interfaces
+ - One high-speed USB 3.0 controller with integrated PHY and one high-speed
+ USB 2.00 controller with ULPI
+ - Integrated flash controller (IFC) with 16-bit interface
+ - Quad SPI NOR Flash
+ - One enhanced Secure digital host controller
+ - Display controller unit (DCU) 24-bit RGB (12-bit DDR pin interface)
+ - Ten UARTs comprised of two 16550 compliant DUARTs, and six low power
+ UARTs
+ - Three I2C controllers
+ - Eight FlexTimers four supporting PWM and four FlexCAN ports
+ - Four GPIO controllers supporting up to 109 general purpose I/O signals
+ - Integrated advanced audio block:
+ - Four synchronous audio interfaces (SAI)
+ - Sony/Philips Digital Interconnect Format (SPDIF)
+ - Asynchronous Sample Rate Converter (ASRC)
+ - Hardware based crypto offload engine
+ - IPSec forwarding at up to 1Gbps
+ - QorIQ Trust Architecture, Secure Boot, and ARM TrustZone supported
+ - Public key hardware accelerator
+ - True Random Number Generator (NIST Certified)
+ - Advanced Encryption Standard Accelerators (AESA)
+ - Data Encryption Standard Accelerators
+ - QUICC Engine ULite block
+ - Two universal communication controllers (TDM and HDLC) supporting 64
+ multichannels, each running at 64 Kbps
+ - Support for 256 channels of HDLC
