裸机程序指令集
本文主要对之前的裸机程序综合，从而实现裸机指令集项目。
项目简介：打印简易的linux界面，实现指令操控裸机程序
项目硬件：S5PV210开发版，串口线，SD卡
项目内容:
1.模拟210启动方式，实现本项目程序加载过程
210在启动过程：上电读取BL0程序，BL0实现观看门狗，初始化时钟，初始化堆和栈，判断启动方式（SD卡或Uart或USB启动）等并且读取代码BL1(16KB）到iSRAM，运行BL1代码来初始化NandFlash，再读取BL2到IRAM运行代码初始化DRAM,将OS读到DRAM,启动OS
项目程序启动：上电读取BL1，BL1（16KB）打开软开关，管看门狗，打开icache,设置SVC栈，初始化SDRAM，读取BL2到SDRAM，BL2实现linux界面和指令集
2.模拟uboot启动延时和环境变量
使用中断程序模拟uboot启动延时，以及环境变量增删改查
3.指令集实现(包含命令提示)
LED灯开关：led on|off
ADC采样：adc sample
蜂鸣器开关：buzzer on|off
lcd：
划线（（x1,y1）,(x2,y2)两点）：lcd line x1 y1 x2 y2
画圆（圆心（x1,y1），半径r）：lcd circle x1 y1 r
打印字符串(data 为要打印的字符串)：lcd string data
env(环境变量)：
打印环境变量：env print
修改/添加环境变量(已经存在该变量则修改，否则添加该变量)：env set env_name env_val
删除环境变量:env delete env_name
项目结果示例（不包含硬件结果：lcd，buzzer，led）：
