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！

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,
};
