![]() When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |

Overview -------- The LS1021AQDS 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 supporting speeds up to 1600Mtps - ECC and interleaving support - VeTSEC Ethernet complex - Up to 3x virtualized 10/100/1000 Ethernet controllers - MII, RMII, RGMII, and SGMII support - QoS, lossless flow control, and IEEE 1588 support - 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 LS1021AQDS board Overview ------------------------- - DDR Controller - Supports rates of up to 1600 MHz data-rate - Supports one DDR3LP UDIMM, of single-, dual- types. - IFC/Local Bus - NAND flash: 512M 8-bit NAND flash - NOR: 128MB 16-bit NOR Flash - Ethernet - Three on-board RGMII 10/100/1G ethernet ports. - FPGA - Clocks - System and DDR clock (SYSCLK, DDRCLK) - SERDES clocks - Power Supplies - SDHC - SDHC/SDXC connector - Other IO - Two Serial ports - Three I2C ports Memory map ----------- The addresses in brackets are physical addresses.
