解压缩3.3.7内核
tar jxf linux-3.3.7.tar.bz2 -C /
cd /linux/3.3.7
修改基本make环境
vim Makefile
195: ARCH = arm
196: CROSS_COMPILE = arm-linux-
运行make help中找出最接近的平台
make s3c6400_defconfig
勾选平台MINI6410 注：s3c6410也可以，但是s3c6410默认并无网络支持
make menuconfig
System Type --->
[*] MINI6410
uboot bootm启动时会像内核传递平台代码，设法解决平台编号问题
================= MACH-ID =================
u-boot:
vim include/configs/up6410_nand.h
or include/configs/up6410_sd.h
//#define MACH_TYPE 1626
#define MACH_TYPE 2520
or kernel:
vim arch/arm/tools/mach-types
#mini6410 MACH_MINI6410 MINI6410 2520
mini6410 MACH_MINI6410 MINI6410 1626
#smdk6410 MACH_SMDK6410 SMDK6410 1626
勾选相关的选项使内核支持NFS文件系统
=================== NFS ===================
make menuconfig
[*] Networking support --->
Networking options --->
[*] TCP/IP networking
[*] IP: kernel level autoconfiguration
