This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

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 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 LS1021ATWR board Overview ------------------------- - DDR Controller - Supports rates of up to 1600 MHz data-rate - Supports one DDR3LP SDRAM. - IFC/Local Bus - NOR: 128MB 16-bit NOR Flash - Ethernet - Three on-board RGMII 10/100/1G ethernet ports. - CPLD - Clocks - System and DDR clock (SYSCLK, DDRCLK) - SERDES clocks - Power Supplies - SDHC - SDHC/SDXC connector - Other IO - One Serial port - Three I2C ports Memory map ----------- The addresses in brackets are physical addresses.
