+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.
+
+The LS1021A SoC includes the following function and features:
+
+ - ARM Cortex-A7 MPCore compliant with ARMv7-A architecture
+ - Dual high-preformance ARM Cortex-A7 cores, each core includes:
+   - 32 Kbyte L1 Instruction Cache and Data Cache for each core (ECC protection)
+   - 512 Kbyte shared coherent L2 Cache (with ECC protection)
+   - NEON Co-processor (per core)
+   - 40-bit physical addressing
+   - Vector floating-point support
+ - ARM Core-Link CCI-400 Cache Coherent Interconnect
+ - One DDR3L/DDR4 SDRAM memory controller with x8/x16/x32-bit configuration

+ - 4-lane 6GHz SerDes
+ - High speed interconnect (4 SerDes lanes with are muxed for these protocol)
+   - 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
+ - QorIQ TrustArchitecture with Secure Boot, as well as ARM TrustZone supported
