（2）移植nand驱动 复制s3c_nand.c
修改Kconfig config MTD_NAND_S3C tristate "NAND Flash support for S3C SoC" depends on ARCH_S3C64XX && MTD_NAND help This enables the NAND flash controller on the S3C.
No board specfic support is done by this driver, each board must advertise a platform_device for the driver to attach.
config MTD_NAND_S3C_DEBUG bool "S3C NAND driver debug" depends on MTD_NAND_S3C help Enable debugging of the S3C NAND driver
config MTD_NAND_S3C_HWECC bool "S3C NAND Hardware ECC" depends on MTD_NAND_S3C help Enable the use of the S3C's internal ECC generator when using NAND. Early versions of the chip have had problems with incorrect ECC generation, and if using these, the default of software ECC is preferable.
If you lay down a device with the hardware ECC, then you will currently not be able to switch to software, as there is no implementation for ECC method used by the S3C
修改makefile obj-$(CONFIG_MTD_NAND_S3C) += s3c_nand.o
启动后

还是不能加载mtdblock2 ？？？
原来是没有选上yaffs2支持，重新编译内核，已经可以加载原先烧录在板子上的android0.09内核

（3）移植触摸屏驱动 复制/drivers/input/touchscreen s3c-ts.c
Kconfig中添加 config TOUCHSCREEN_S3C tristate "S3C touchscreen driver" depends on ARCH_S3C2410 || ARCH_S3C64XX || ARCH_S5PC1XX default y help Say Y here to enable the driver for the touchscreen on the S3C SMDK board.
If unsure, say N.
To compile this driver as a module, choose M here: the module will be called s3c_ts.
config TOUCHSCREEN_NEW bool "new flip touch" depends on TOUCHSCREEN_S3C default y help Say Y here to enable the driver for the new version touchscreen on the S3C SMDK board.
Say N here to enable the driver for the old version touchscreen on the S3C SMDK board.
Makefile中添加 obj-$(CONFIG_TOUCHSCREEN_S3C) += s3c-ts.o
make menuconfig中添加 --- Touchscreens │ │ │ │ <*> S3C touchscreen driver │ │ │ │ [*] new flip touch
开机提示： S3C Touchscreen driver, (c) 2008 Samsung Electronics S3C TouchScreen got loaded successfully : 12 bits input: S3C TouchScreen as /class/input/input0
测试OK
(4)移植DM9000网卡驱动，这是最痛苦的部分！因为2.6.29内核没有做，得从开发板提供的2.6.24内核中移植，但是开发板这一块写的很不标准，用了很多24xx的头文件，导致移植非常痛苦。
1）这是正确的加载内容，参考 dm9000 Ethernet Driver eth%d: con201 Invalid ethernet MAC address. using default config, Please set using ifconfig eth0: dm9000 at f7200300,f7200304 IRQ 71 MAC: 00:e0:4a:bc:15:e7
2）从开发板提供的2.6.24内核中将dm9000_con201.c提出，编译，发现问题
CHK include/linux/compile.h CC drivers/net/dm9000_con201.o drivers/net/dm9000_con201.c:74:31: error: asm/arch/regs-irq.h: No such file or directory drivers/net/dm9000_con201.c:75:31: error: asm/arch/regs-mem.h: No such file or directory drivers/net/dm9000_con201.c:76:32: error: asm/arch/regs-gpio.h: No such file or directory drivers/net/dm9000_con201.c: In function 'dm9000_probe': drivers/net/dm9000_con201.c:417: error: 'S3C_SROM_BW' undeclared (first use in this function) drivers/net/dm9000_con201.c:417: error: (Each undeclared identifier is reported only once drivers/net/dm9000_con201.c:417: error: for each function it appears in.) drivers/net/dm9000_con201.c:422: error: 'S3C_SROM_BC1' undeclared (first use in this function) drivers/net/dm9000_con201.c:425: error: 'S3C_GPNCON' undeclared (first use in this function) drivers/net/dm9000_con201.c:426: error: 'S3C_GPNPU' undeclared (first use in this function) drivers/net/dm9000_con201.c:428: error: 'S3C_EINT0CON0' undeclared (first use in this function) drivers/net/dm9000_con201.c:430: error: 'S3C_EINTFLTCON0' undeclared (first use in this function) drivers/net/dm9000_con201.c:432: error: 'S3C_EINTPEND' undeclared (first use in this function) drivers/net/dm9000_con201.c:433: error: 'S3C_EINT0MASK' undeclared (first use in this function) make[2]: *** [drivers/net/dm9000_con201.o] 错误 1 make[1]: *** [drivers/net] 错误 2 make: *** [drivers] 错误 2 [kyon@SEP4020 kernel-6410]$
需要这3个头文件 drivers/net/dm9000_con201.c:74:31: error: asm/arch/regs-irq.h: No such file or directory drivers/net/dm9000_con201.c:75:31: error: asm/arch/regs-mem.h: No such file or directory drivers/net/dm9000_con201.c:76:32: error: asm/arch/regs-gpio.h: No such file or directory
3）继续出现问题
CHK include/linux/compile.h CC drivers/net/dm9000_con201.o drivers/net/dm9000_con201.c: In function 'dm9000_probe': drivers/net/dm9000_con201.c:419: error: 'S3C24XX_VA_SROMC' undeclared (first use in this function) drivers/net/dm9000_con201.c:419: error: (Each undeclared identifier is reported only once drivers/net/dm9000_con201.c:419: error: for each function it appears in.) drivers/net/dm9000_con201.c:427: error: 'S3C24XX_VA_GPIO' undeclared (first use in this function) make[2]: *** [drivers/net/dm9000_con201.o] 错误 1 make[1]: *** [drivers/net] 错误 2 make: *** [drivers] 错误 2 [kyon@SEP4020 kernel-6410]$
这里有问题，经过测试要添加如下内容 //add by kyon #define S3C24XX_VA_SROMC S3C_VA_SROMC #define S3C24XX_VA_GPIO S3C64XX_VA_GPIO//S3C_VA_GPIO //add end
4）发现需要在arch/arm中添加启动信息 plat-smdk64xx目录的dev. c //add by kyon #include <linux/dm9000.h>
#define S3C_VA_DM9000nc1 S3C_ADDR(0x03200300) #define S3C24XX_VA_DM9000CS1 S3C_VA_DM9000nc1 #define S3C24XX_SZ_DM9000CS1 SZ_1M
#define DM9000_ETH_IRQ_EINT0 S3C_EINT(7)//IRQ_EINT7 //这儿要注意！原来的IRQ_EINT7一定要改掉！
static struct resource dm9000_resources_cs1[] = { [0] = { .start = S3C24XX_VA_DM9000CS1, .end = (S3C24XX_VA_DM9000CS1+ S3C24XX_SZ_DM9000CS1), .flags = IORESOURCE_MEM, }, [1] = { .start = (DM9000_ETH_IRQ_EINT0), .end = (DM9000_ETH_IRQ_EINT0), .flags = IORESOURCE_IRQ, }, };
static struct dm9000_plat_data dm9000_setup_cs1 = { .flags = DM9000_PLATF_16BITONLY };
struct platform_device s3c_device_dm9000_cs1 = { .name = "dm9000_con201", .id = 0, .num_resources = ARRAY_SIZE(dm9000_resources_cs1), .resource = dm9000_resources_cs1, .dev = { .platform_data = &dm9000_setup_cs1, } };
EXPORT_SYMBOL(s3c_device_dm9000_cs1);
还要修改文件mach-smdk6410.c 一些定义，又重复定义了，应该放在一个通用的头文件中 //kyon extern struct platform_device s3c_device_dm9000_cs1;
#define S3C_VA_DM9000nc1 S3C_ADDR(0x03200300)
#define S3C24XX_VA_DM9000CS1 S3C_VA_DM9000nc1 #define S3C6400_PA_DM9000CS1 (0x18000300) #define S3C24XX_SZ_DM9000CS1 SZ_1M
在启动结构体中添加 static struct platform_device *smdk6410_devices[] __initdata = &s3c_device_dm9000_cs1,
还要添加地址映射： static struct map_desc smdk6410_iodesc[] __initdata = { { .virtual = (u32)S3C24XX_VA_DM9000CS1, .pfn = __phys_to_pfn(S3C6400_PA_DM9000CS1), .length = S3C24XX_SZ_DM9000CS1, .type = MT_DEVICE, }, };
前面没进行地址映射，开机不断内核崩溃，做到这里终于不内核内核崩溃
