TQ2440内核linux2.6.28移植

转自：http://blog.sina.com.cn/s/blog_95268f5001013ibg.html

内核的移植，是在u-boot的基础上进行的，所以u-boot在这之前一定要先弄好才好

怎样下载源码就不说了，下载后进入内核根目录/linux-2.6.28，修改根目录下Makefile大概193行改成下面这样：
193 ARCH ?= arm
194 CROSS_COMPILE ?=arm-linux-
接着进入这个目录linux-2.6.28/arch/arm/configs（如果没有就从网上下载补丁），在该目录下面可以看到
s3c2410_defconfig这个文件，这个就是我们要用到的默认配置文件，这是在内核根目录下执行
linux-2.6.28# make s3c2410_defconfig
#
# configuration written to .config
#
这样我们就建立起默认.config文件
接下来
linux-2.6.28#make menuconfig进入配置界面

接下来
（1）
System Type --->
S3C2410 Machines --->
[*] SMDK2410/A9M2410
[ ] IPAQ H1940
[ ] Acer N30
[ ] Simtec Electronics BAST (EB2410ITX)
[ ] NexVision OTOM Board
[ ] AML M5900 Series
[ ] Thorcom VR1000
[ ] QT2410
S3C2412 Machines --->
[ ] SMDK2413
[ ] SMDK2412
[ ] VMSTMS
S3C2440 Machines --->
[ ] Simtec Electronics ANUBIS
[ ] Simtec IM2440D20 (OSIRIS) module
[ ] HP iPAQ rx3715
[*] SMDK2440
[ ] NexVision NEXCODER 2440 Light Board
[*] SMDK2440 with S3C2440 CPU module
S3C2442 Machines --->
[ ] SMDM2440 with S3C2442 CPU module
S3C2443 Machines --->
[ ] SMDK2443

（2）在配置菜单中添加自己信息
General setup --->
(-EmbedSky) Local version - append to kernel releas
[*] System V IPC
(17) Kernel log buffer size (16 => 64KB, 17 => 128KB)
（3）选择是否支持EABI
Kernel Features --->
[ ] Preemptible Kernel (EXPERIMENTAL)
[ ] Dynamic tick timer
[*] Use the ARM EABI to compile the kernel
[*] Allow old ABI binaries to run with this kernel (EXPERIMENTA）
[*] Allow old ABI binaries to run with this kernel (EXPERIMENTA）
Memory model (Flat Memory) --->
[ ] 64 bit Memory and IO resources (EXPERIMENTAL)
196 static void __init smdk2440_map_io(void)
197 {
198 s3c24xx_init_io(smdk2440_iodesc, ARRAY_SIZE(smdk2440_iodesc));
上面红色部分如果是使用4.3.3（也就是支持EABI）编译链就选它，3.4.5以下就不用选
到了这里就差不多配置完了，要改动的不是很多，还要配置的下面再配，这时保存推出就可以了。
由于我们2440的晶振是12M的，而默认中不是这样，所以下面要改晶振，在arch/arm/mach-s3c2440/mach-smdk2440.c这个文件里改，如下：
199 s3c24xx_init_clocks(12000000);
200 s3c24xx_init_uarts(smdk2440_uartcfgs, ARRAY_SIZE(smdk2440_uartcfgs));
201 }
接下来修改机器码，在U-boot中用了168，所以这里也要改
在arch/arm/tools/mach-types文件里，改成如下：
379 s3c2440 ARCH_S3C2440 S3C2440 168

到了这里，就差不多了，这时make uImage生成uImage镜像
没有错的话会在arch/arm/boot生成uImage和zzimage
顺利的话如下：

下面来建立flash分区，这里的分区最好与我们在u-boot时分区对应，当然也可以不一样的，只是为了方便
在vim arch/arm/plat-s3c24xx/common-smdk.c文件里就可以修改自己喜欢的分区，如下：
109 static struct mtd_partition smdk_default_nand_part[] = {
110 [0] = {
111 .name = "u-boot",
112 .size = 0x40000,
113 .offset = 0x00000000,
114 },
115 [1] = {
116 .name = "krenel",
117 .offset = 0x200000,
118 .size = 0x200000,
119 },
120 [2] = {
121 .name = "jffs2",
122 .offset = 0x400000,
123 .size = SZ_8M,
124 },
125 [3] = {
126 .name ="yaffs2",
127 .offset = MTDPART_OFS_APPEND,
128 .size = MTDPART_SIZ_FULL,
129 }

然后还要修改nand flash读写匹配时间，在同一个文件里改
145 static struct s3c2410_platform_nand smdk_nand_info = {
146 .tacls = 10,
147 .twrph0 = 25,
148 .twrph1 = 10,
149 .nr_sets = ARRAY_SIZE(smdk_nand_sets),
150 .sets = smdk_nand_sets,
151 };
152
接下来还要修改 drivers/mtd/nand/Kconfig 增加对各种nand flash支持，如下
165 choice
166 prompt"Nand Flash Capacity select"
167 depends on MTD
168 help
169 EmbedSKy Board Nand Flash Capacity select
170 config EmbeddSky_64MB_NAND
171 boolean "64MB Nand for EmbedSky Board"
172 depends on MTD
173 help
174 Set 64MB Nand parts
175 config EmbeddSky_128MB_NAND
176 boolean "128MB Nand for EmbedSky Board"
177 depends on MTD
178 help
179 Set 128MB Nand parts
180 config EmbeddSky_more_than_256MB__NAND
181 boolean "256MB~1GB Nand for EmbedSky Board"
182 depends on MTD
183 help
184 Set 256MB~1GB Nand parts
185 endchoice
增加对应驱动配置，再次执行make menucofig进入配置界面
Device Drivers --->
<*> Memory Technology Device (MTD)support
<*> NAND Device Support --->
[*] S3C2410 NAND HardwareECC
Nand Flash Capacity select (256MB~1GB Nand for EmbedSky Board) --->
这时从新编译就好了
Creating 4 MTD partitions on "NAND 256MiB 3,3V 8-bit":
0x00000000-0x00040000 : "u-boot"
0x00200000-0x00400000 : "krenel"
0x00400000-0x00c00000 : "jffs2"
0x00c00000-0x10000000 : "yaffs2"
usbmon: debugfs is not available

接下来移植yaffs文件系统
（1）可以从www.alephl.co.uk/cgi-bin/viewcvs.cgi/获得源码
（2）将yaffs代码加进内核（打补丁就行）
首先进入你下载yaffs2所在目录，我的是#/work/cvs/yaffs2，然后执行如下命令
#./patch-ker.sh c /work/linux-2.6.28
这样就行了
（3）接下来就是配置增加对yaffs2的支持了
#make menuconfig
File systems --->
Miscellaneous filesystems --->
<*> YAFFS2 file system support
要打上补丁才会有这个选择的。
到了这里yaffs2文件系统移植完了。。。。。。。
接下来就是yaffs2文件系统的制作了。。。。。。。。。
