linux-2.6.20移植相关

wushuan10141

(1)准备工作
内核下载地址：
http://www.kernel.org/pub/linux/kernel/
9260补丁下载地址：
http://maxim.org.za/at91_26.html
须在linux下下载，XP下打补丁时会出错！
解压内核：tar jxvf linux-2.6.20.tar.bz2
补丁：zcat 2.6.20-at91.patch.gz | patch -p1

(2)修改内核使支持9260并能编译成功：
修改该目录下的Makefile文件
ARCH ?=$(SUBARCH)
CROSS_COMPILE ?=
改成：
ARCH = arm
CROSS_COMPILE =arm-linux-

获取9260的配置：make at91sam9260ek_defconfig 或者
cp arch/arm/configs/at91sam9260ek_defconfig ./config
make clean
make uImage
出错：
scripts/mod/sumversion.c: In function ‘get_src_version’:
scripts/mod/sumversion.c:384: error: ‘PATH_MAX’ undeclared (first use in this function)
scripts/mod/sumversion.c:384: error: (Each undeclared identifier is reported only once
scripts/mod/sumversion.c:384: error: for each function it appears in.)
scripts/mod/sumversion.c:384: warning: unused variable ‘filelist’
在sumversion.c中加入 #define

然后重新编译即可
