linux-2.6.30的内核移植到MINI2440

之前弄了很久的LINUX-2.6.31版本的，但是还是弄不出来，老是有很多的错误的，就是怎么也加载不了文件系统，所有我干脆就放弃了，来弄点底版本的，2.6.30版本。
很多书基本上都是这样写的

1.修改顶层Makefile文件
直接将Makefile文件里面的
ARCH ?= $(SUBARCH)
CROSS_COMPILE ?=
改为:
ARCH ?= arm
CROSS_COMPILE ?=arm-linux-

然后用S3C2410的默认配置文件
cp arch/arm/congfigs/s3c2410_defconfig .config 就是加载配置文件。S3C2410和S3C2440差不多的，
然后修改分区
来修改我们的arch/arm/plat-s3c24xx/common-smdk.c

主要修改smdk_default_nand_part[]
{
[0] = {
.name = “supervivi”,
.size = 0x00060000,
.offset = 0,
},
[1] = {
.name = “Kernel”,
.offset = 0x00060000,
.size = 0x00200000,
},
[2] = {
.name = “root”,
.offset = 0x00260000,
.size = 1024*1024*1024,
},
[3] = {
.name = “nand”,
.offset = 0x00000000,
.size = 1024*1024*1024,
}
};
后面的就用#if 0
……
4，5，6，7分区不用了
#endfi
在arch/arm/mach-s3c2440/mach-smdk2440.c
修改下时钟频率
s3c24xx_init_clocks(12000000);

在内核修改下Boot Option >Default kernel command sring的内容
noinitrd root=/dev/mtdblock2 init=/linuxrc console =ttySAC0,115200 mem=64M

加载YAFFS2
可以在网上下载，也可以用友善的CP下来，但是要在fs/KCONFIG 文件和fs/MAKEFILE的文件加入。可以参考友善提供的

到网上下载ysffs2源代码,解压之后进行如下修改:

./patch-ker.sh c /2440/linux-2.6.29

上面命令完成下面三件事情
(1)修改内核fs/Kconfig
增加一行:source "fs/yaffs2/Kconfig"
(2)修改内核fs/Kconfig
增加一行ojb-$(CONFIG_YAFFS_FS) +=yaffs2/
(3)在内核fs/目录下创建yaffs2目录
将yaffs2源码目录下面的Makefile.kernel文件复制为内核fs/yaffs2/Makefie;
将yaffs2 源码目录的Kconfig文件复制到内核fs/yaffs2目录下;
将yaffs2源码目录下的*.c *.h文件复制到内核fs/yaffs2目录下.
在内核根目录下执行:
#make menuconfig 配置yaffs2文件支持
File systems --->
Miscellaneous filesystems --->
<*>YAFFS2 file system support

到这里就差不多了，但是还要改下机器ID为1999
在arch/arm/tools/mach-types里面，原本问s3c2440 ARCH_S3C2440 S3C2440 362
的把362改为1999
最后输出为MACH_TYPE = 1999
