T113 Longan 系统配置(Linux)

本系列调试说明记录了Linux在全志T113-S3/S4平台上的移植过程，说明过程中可能会技术瑕疵，希望大家提供宝贵意见。
本文移植的硬件平台来自于盈鹏飞嵌入式的SBC-T113S(处理器是T113-S3)主板。

SBC-T113S产品特性：

•  采用Allwinner公司Cortex-A7双核T113-S3/S4处理器，运行最高速度为1.2GHZ；
• 内置64-bit XuanTie C906 RISC-V协处理器(仅T113-S4支持)；
• 支持JPEG/MJPEG视频编码，最大分辨率1080p@60fps；支持多格式1080P@60fps视频解码 (H.265,H.264, MPEG-1/2/4)；
• 支持RGB666/LVDS/MIPI-DSI，分辨率最高1920x1080；
• 支持128-256M Bytes DDR3 SDRAM,其中T113-S3内置128MB;T113-S4内置256MB；
• 支持SPI NAND存储和启动(默认：256MB；最大1GB)或者EMMC启动(默认：4GB,最大32GB)；
• 支持一路USB2.0 OTG(设计为TYPE-A接口)；支持二路USB2.0 HOST;
• 支持七路RS232通信或者6路RS232和1路RS485(隔离)；
• 支持一路CAN BUS通信（隔离）；
• 支持一路10/100M以太网；
• 稳定的操作系统的支持，可预装LINUX 5.4或者OpenWRT；
• 经典尺寸主板，尺寸为120*100MM；
