OK6410（256M RAM ，1G SLC NAND）Uboot-2013-04移植（1）--SD卡启动

环境：ubuntu13.10 arm-linux-gcc4.4.1 OK6410（256M RAM ，1G SLS NAND）

1.修改U-boot-2013.04目录下的Makefile文件

    1.1 在CROSS_COMPILE ?=这里修改：

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

    1.2 把makefile里面的6400全部替换成6410

2.文件的复制和修改

     2.1 拷贝board/samsung/smdk6400目录里的所有文件 到board/samsung/smdk6410目录中

            更改board/samsung/smdk6410目录下smdk6400.c 为smdk6410.c ,

            更改board/samsung/smdk6410目录下smdk6400_nand_spl.c为smdk6410_nand_spl.c

            修改board/samsung/smdk6410目录下所有文件，将所有文件中的6400替换为6410

            修改board/samsung/smdk6410目录下lowlevel_init.S文件225行ldr r1, =0x200203为ldr r1, =0x80200203

            修改board/samsung/smdk6410目录下lowlevel_init.S文件，参考OK6410的管脚设置把

/* LED on only #8 */
ldr r0, =ELFIN_GPIO_BASE
ldr r1, =0x55540000
str r1, [r0, #GPNCON_OFFSET]
ldr r1, =0x55555555
str r1, [r0, #GPNPUD_OFFSET]
ldr r1, =0xf000
str r1, [r0, #GPNDAT_OFFSET]
修改为
/* LED on only #8 */
ldr r0, =ELFIN_GPIO_BASE
ldr r1, =0x00001111

    2.2 拷贝nand_spl/board/samsung/smdk6400目录里的所有文件 到 nand_spl/board/samsung/smdk6410目录中

            修改nand_spl/board/samsung/smdk6410目录下所有文件，将所有文件中的6400替换为6410

            修改nand_spl/board/samsung/smdk6410目录下Makefile文件，40行修改为SOBJS = start.o cpu_init.o lowlevel_init.o crt0.o

            修改nand_spl/board/samsung/smdk6410目录下Makefile文件，在

$(obj)start.S:
    @rm -f $@
    @ln -s $(TOPDIR)/arch/arm/cpu/arm1176/start.S $@
后添加
$(obj)crt0.S:
    @rm -f $@
    @ln -s $(TOPDIR)/arch/arm/lib/crt0.S $@

                                注意@前为tab键

    2.3 把arch/arm/include/arch-s3c64xx目录里的s3c6400.h拷贝一份到当前目录，并重命名为s3c6410.h

            把s3c6410.h中的所有6400替换成6410

            把820行开始的

#define DMC1_MEM_CFG 0x00010012 /* burst 4, 13-bit row, 10-bit col */
#define DMC1_MEM_CFG2 0xB45
#define DMC1_CHIP0_CFG 0x150F8 /* 0x5000_0000~0x57ff_ffff (128 MiB) */
#define DMC_DDR_32_CFG 0x0 /* 32bit, DDR */

#define DMC1_CHIP0_CFG 0x150F0 /* 0x5000_0000~0x6000_0000 (256 MiB) */
#define DMC_DDR_32_CFG 0x0 /* 32bit, DDR */

                    用以支持256MB内存

    2.4 把arch/arm/cpu/arm1176/s3c64xx/Makefile 中的COBJS-$(CONFIG_S3C6400)改为COBJS-$(CONFIG_S3C6410)

            修改arch/arm/cpu/arm1176/s3c64xx目录下所有文件，将所有文件中的#include 替换为

#ifdef CONFIG_S3C6400
#include <asm/arch/s3c6400.h>
#else
#include <asm/arch/s3c6410.h>
#endif

    2.5 把include/目录下的common.h文件的第644行 defined(CONFIG_S3C6400) || \ 下添加defined(CONFIG_S3C6410) || \

            把drivers/usb/host目录下的ohci-hcd.c文件的第69行 defined(CONFIG_S3C6400) || \ 下添加defined(CONFIG_S3C6410) || \

#include <common.h>
#include <asm/io.h>
#ifdef CONFIG_MMC_CHANNEL
#define MMC_CHANNEL CONFIG_MMC_CHANNEL
#else
#define MMC_CHANNEL 0
#endif
#define ELFIN_HSMMC_BASE (0x7C200000 + MMC_CHANNEL*0x10000)
#define HM_CONTROL4 (ELFIN_HSMMC_BASE+0x8C)
#define globalBlockSizeHide *((volatile unsigned int*)(0x0C004000-0x4))
#define globalSDHCInfo *((volatile unsigned int*)(0x0C004000-0x8))
#define LAST_BLKPOS (globalBlockSizeHide - 2)
#define BLK_SIZE 512
#define BL1_SIZE (1024*8)
#define BL2_SIZE (300*1024)
#if 0

#define DESTADDR CONFIG_SYS_PHY_UBOOT_BASE
#define CopyMMCtoMem(a,b,c,d,e) (((int(*)(int, uint, ushort, uint *, int)) \
(*((uint *)(0x0C004000 + 0x8))))(a,b,c,d,e))
int BootCopyMMCtoMem()
{
writel(readl(HM_CONTROL4) | (0x3 << 16), HM_CONTROL4);
return CopyMMCtoMem(0, STARTBLKADDR, BL2_BLKCNT, (uint *)DESTADDR, 0);
}

    2.8 修改 arch/arm/cpu/arm1176/s3c64xx/目录下的Makefile的COBJS-$(CONFIG_S3C6410) += cpu_init.o speed.o下面添加

                                                                                            COBJS-$(CONFIG_BOOT_SD) += s3c6410_sdboot.o

            修改 arch/arm/cpu/arm1176/目录下的Start.S，把

bl lowlevel_init
bl _main
修改为
bl lowlevel_init /* go setup pll,mux,memory */
#if defined(CONFIG_BOOT_SD) && !defined(CONFIG_NAND_SPL)
ldr sp, =CONFIG_SYS_INIT_SP_ADDR
bl BootCopyMMCtoMem
cmp r0, #0
copyerror:
beq copyerror
ldr pc, =_main
#else
bl _main
#endif

   
     2.9 修改board/samsung/smdk6410目录下u-boot-nand.lds文件 ，在 arch/arm/cpu/arm1176/start.o (.text)下添加

                                                             board/samsung/smdk6410/libsmdk6410.o (.text)

    2.10 把include/configs目录里的smdk6400.h拷贝一份到当前目录，并重命名为smdk6410.h
            在smdk6410.h的41行下添加#define CONFIG_BOOT_SD

            把smdk6410.h中的所有6400替换成6410

            166行改为#define PHYS_SDRAM_1_SIZE 0x10000000 /* 256 MB in Bank #1 */

3.编译和结果

    执行make distclean

    执行make smdk6410_config

    执行make all

    把编译出的u-boot.bin通过SD-write软件烧写到SD卡，开发板拨到SD卡启动，DNW显示如下
