前面介绍了基于mini6410来移植，这次完全由自己从头移植，以mach-smdk6410.c为基础！

1、nand flash MTD分区移植(拿来主义不是mini6410可以，模仿它的)

a、

static struct mtd_partition smdk6410_nand_part[] = {

[0] = {

.name = "uboot",

.size = SZ_1M,

.offset = 0,

},

[1] = {

.name = "kernel",

.size = SZ_2M,

.offset = SZ_1M,

},

[2] = {

.name = "rootfs",

.size = MTDPART_SIZ_FULL,

.offset = SZ_1M + SZ_2M,

},

};

static struct s3c2410_nand_set smdk6410_nand_sets[] = {

[0] = {

.name = "nand",

.nr_chips = 1,

.nr_partitions = ARRAY_SIZE(smdk6410_nand_part),

.partitions = smdk6410_nand_part,

},

};

static struct s3c2410_platform_nand smdk6410_nand_info = {

.tacls = 25,

.twrph0 = 55,

.twrph1 = 40,

.nr_sets = ARRAY_SIZE(smdk6410_nand_sets),

.sets = smdk6410_nand_sets,

};

b、

static struct platform_device *smdk6410_devices[] __initdata = {

。。。。。。。。。。。。。

//add by hcm

&s3c_device_nand,

};

static void __init smdk6410_machine_init(void)

{

u32 cs1;

s3c_i2c0_set_platdata(NULL);

s3c_i2c1_set_platdata(NULL);

s3c_fb_set_platdata(&smdk6410_lcd_pdata);

s3c_hsotg_set_platdata(&smdk6410_hsotg_pdata);

samsung_keypad_set_platdata(&smdk6410_keypad_data);

//add by hcm

s3c_nand_set_platdata(&smdk6410_nand_info);

到这我想直接去编译，然后发现少哪些头文件可是不加头文件就出现：

make[1]: *** [arch/arm/mach-s3c64xx/mach-smdk6410.o] 错误 1

make: *** [arch/arm/mach-s3c64xx] 错误 2

c、不得已只能对照mini6410加入相关头文件

//add by hcm

#include <linux/mtd/mtd.h>

#include <linux/mtd/partitions.h>

#include <plat/nand.h>

编译ok！

S3C24XX NAND Driver, (c) 2004 Simtec Electronics

0x000000300000-0x000010000000 : "rootfs"



2、DM9000移植



a、

/* DM9000AEP 10/100 ethernet controller */

static struct resource mini6410_dm9k_resource[] = {

[0] = DEFINE_RES_MEM(S3C64XX_PA_XM0CSN1, 2),

[1] = DEFINE_RES_MEM(S3C64XX_PA_XM0CSN1 + 4, 2),

[2] = DEFINE_RES_NAMED(S3C_EINT(7), 1, NULL, IORESOURCE_IRQ \

| IORESOURCE_IRQ_HIGHLEVEL),

};

static struct dm9000_plat_data mini6410_dm9k_pdata = {

.flags = (DM9000_PLATF_16BITONLY | DM9000_PLATF_NO_EEPROM),

};

static struct platform_device mini6410_device_eth = {

.name = "dm9000",

.id = -1,

.num_resources = ARRAY_SIZE(mini6410_dm9k_resource),

.resource = mini6410_dm9k_resource,

.dev = {

.platform_data = &mini6410_dm9k_pdata,

},

};

b、

&smdk6410_device_eth,

c、

#include <linux/dm9000.h>

3、简单的lcd支持

static struct s3c_fb_pd_win smdk6410_fb_win0 = {

.max_bpp = 32,

.default_bpp = 16,

.xres = 800,

.yres = 480,

.virtual_y = 480 * 2,

.virtual_x = 800,

};

static struct fb_videomode smdk6410_lcd_timing = {

.left_margin = 8,

.right_margin = 13,

.upper_margin = 7,

.lower_margin = 5,

.hsync_len = 3,

.vsync_len = 1,

.xres = 800,

.yres = 480,

};

改为4.3寸lcd

static struct s3c_fb_pd_win smdk6410_fb_win0 = {

.max_bpp = 32,

.default_bpp = 16,

.xres = 480,

.yres = 272,

.virtual_y = 272 * 2,

.virtual_x = 480,

};

static struct fb_videomode smdk6410_lcd_timing = {

.left_margin = 2,

.right_margin = 2,

.upper_margin = 2,

.lower_margin = 2,

.hsync_len = 41,

.vsync_len = 10,

.xres = 480,

.yres = 272,

};
