1解壓縮文件
tar -jxf linux-3.0.tar.bz2
cd linux-3.0
2修改makefile，配置CPU類型和交叉編譯器（195,196行）
ARCH ?= arm
CROSS_COMPILE ?= /opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-
注意：在配置交叉編譯器路徑的時候，不要多加多餘的空格，否則編譯器不會被找到，我剛剛修改的cross_compile的時候，就是因爲在arm-linux-後面多加了一個空格，然後編譯器找不到，害得我搞了很久才發現。
添加zImage頭製作（559行後面）
cp arch/arm/boot/zImage . -f
../u-boot-2010.09.bak/tools/mkimage -A arm -O linux -T kernel -C none -a 30008000 -e 30008040 -n "Linux Kernel" -d zImage
linuxrom-s3c2440.bin
rm -f zImage
該段是在linux編譯的內核的前面，加上一個64字節的頭，讓u-boot能夠引導內核啓動
3拷貝 arch/arm/configs/s3c2410_defconfig作爲.config的模板，
make menuconfig
System Type --->
[*] SMDK2440
[*] SMDK2440 with S3C2440 CPU module
Kernel Features --->
[*]UsetheARMEABItocompilethekernel
[*] Allow old ABI binaries to run with this kernel (EXPERIMENTAL)
4修改時鐘和串口
將arch/arm/mach-s3c2440/mach-smdk2440.c中的__init smdk2440_map_io()函數中對時鐘的初始化修改爲12MHz:
s3c24xx_init_clocks(12000000);
將drivers/tty/serial/samsung.c中設置如下：
#define S3C24XX_SERIAL_NAME "ttyS"
將uart_driver s3c24xx_uart_drv結構體中的.driver_name設置爲如下
.driver_name = "ttyS",
5修改arch/arm/tools/mach-types，將machine_ID配置爲如下
s3c2440 ARCH_S3C2440 S3C2440 1999
mini2440 MACH_MINI2440 MINI2440 362
6 開始編譯：make
編譯好了之後，把linxurom-s3c2440.bin 下載到開發板的30008000地址下，啓動，這時候我們發現，我們的開發板已經跑起來了，可以進入內核了。
