OK6410（256M RAM ，1G SLC NAND）Linux-3.8.3移植 （1）编译

1.把uboot-2013-04目录下/tools/mkimage文件复制到ubuntu的/usr/bin/目录下

2.修改linux-3.8.3目录下的Makeflie，添加交叉编译链

ARCH        ?= arm
CROSS_COMPILE    ?= /usr/local/arm/4.4.1/bin/arm-linux-

3.进入arch/arm/mach-s3c64xx目录，修改Kconfig，添加

config MACH_OK6410
    bool "OK6410"
    select CPU_S3C6410
    select SAMSUNG_DEV_ADC
    select S3C_DEV_HSMMC
    select S3C_DEV_HSMMC1
    select S3C_DEV_I2C1
    select SAMSUNG_DEV_IDE
    select S3C_DEV_FB
    select S3C_DEV_RTC
    select SAMSUNG_DEV_TS
    select S3C_DEV_USB_HOST
#    select S3C_DEV_USB_HSOTG
    select S3C_DEV_WDT
    select SAMSUNG_DEV_KEYPAD
    select SAMSUNG_DEV_PWM
    select HAVE_S3C2410_WATCHDOG if WATCHDOG
    select S3C64XX_SETUP_SDHCI
    select S3C64XX_SETUP_I2C1
    select S3C64XX_SETUP_IDE
    select S3C64XX_SETUP_FB_24BPP
    select S3C64XX_SETUP_KEYPAD
    help
      Machine support for the feiling OK6410

    在arch/arm/mach-s3c64xx目录下，复制mach-mini6410.c到当前目录并改名为mach-ok6410.c，并把mach-ok6410.c文件中的所有的mini6410修改为ok6410，所有的MINI6410修改为OK6410
    修改arch/arm/mach-s3c64xx/mach-ok6410.c中的static struct mtd_partition ok6410_nand_part 函数

static struct mtd_partition ok6410_nand_part[] = {
    [0] = {
        .name    = "Bootloader",
        .offset    = 0,
        .size    = (1*SZ_1M),
        .mask_flags = MTD_CAP_NANDFLASH,
    },
    [1] = {
        .name    = "Kernel",
        .offset    = (1*SZ_1M),
        .size    = (5*SZ_1M),
        .mask_flags = MTD_CAP_NANDFLASH,
    },
    [2] = {
        .name    = "File System",
        .offset    = (6*SZ_1M),
        .size    = (200*SZ_1M),
    },
    [3] = {
        .name    = "User",
        .offset    = MTDPART_OFS_APPEND,
        .size    = MTDPART_SIZ_FULL,
    },
};

    在arch/arm/mach-s3c64xx目录下的Makefile中，在obj-$(CONFIG_MACH_MINI6410) += mach-mini6410.o下面添加obj-$(CONFIG_MACH_OK6410) += mach-ok6410.o
    修改drivers/mtd/nand/nand_ids.c文件，加入对MT的1G SLS nandflash的支持，添加{"NAND 1GiB 1,8V 8-bit", 0x38, 4096, 1024, 512*1024, LP_OPTIONS},//MT

4. 进入arch/arm/tools目录，打开mach-types文件，添加ok6410      MACH_OK6410      OK6410      1626

5.回到linux-3.8.3目录下，执行make menuconfig

    先选择Load an Alternate Configuration File，输入arch/arm/configs/s3c6400_defconfig 

    选择General Setup,打开Cross_compiler tool perfix,输入/usr/local/arm/4.4.1/bin/arm-linux- 

    选择System Type,取消SMDK6400 ，A&W6410，SMDK6410等平台，只选择OK6410

    选择Save an Alternate Configuration File，保存为.config然后退出。
    执行make uImage
    执行结束后可在arch/arm/boot目录下找到uImage文件

6.把uImage文件拷贝到SD卡中，开发板从nandflash中启动，执行以下命令将uImage拷贝到nandflash的100000-600000中
    

7.重新从从nandflash中启动开发板，结果如下
