移植u-boot-2010.09到Tiny6410开发板
Hyz
一、 开发环境
Fedora13、tiny6410开发板
二、 u-boot
1. 版本：u-boot-2010.09
2. 下载地址：www.denx.de/pub/u-boot/
三、 移植
(一) 首先需建立交叉编译环境
1. 将光盘Linux 目录中的arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz复制到Fedora9
某个目录下如tmp/，然后进入到该目录，执行解压命令：
#cd /tmp
#tar xvzfarm-linux-gcc-4.5.1-v6-vfp-20101103.tgz –C /
注意：C
后面有个空格，并且C 是大写的，它是英文单词“Change”的第一个字母，
在此是改变目录的意思。
如果你没有arm-linux-gcc-4.5.1-v6-vfp-20101103.tgz请到我的QQ空间下载。
执行该命令，将把arm-linux-gcc 安装到/opt/FriendlyARM/toolschain/4.5.1目录。
2. 把编译器路径加入系统环境变量，运行命令
#gedit /root/.bashrc
编辑/root/.bashrc文件，注意“bashrc”前面有一个“.”，修改最后一行为export
PATH=$PATH:/opt/FriendlyARM/toolschain/4.5.1/bin，注意路径一定要写对，否则将不会有效。
如图，保存退出。
重新登录系统(不必重启机器，开始->logout即可)，使以上设置生效，在命令行输入
arm-linux-gcc–v，会出现如下信息，这说明交叉编译环境已经成功安装。
(二) 解压安装源代码
1. 首先创建工作目录
工作目录/opt/FriendlyARM/tiny6410/linux
执行命令：#mkdir–p /opt/FriendlyARM/Tiny6410/linux
2. 将源代码放到linux系统下（使用sharefoder等）
如：放到/mnt/hgfs/share下
3. 解压安装u-boot源代码
在工作目录/opt/FriendlyARM/Tiny6410/linux中执行：
#cd /opt/FriendlyARM/tiny6410/linux
#tarxvzf /mnt/hgfs/share/u-boot-2010.09.tar.gz
会自动生成u-boot-2010.09文件夹
(三) 对u-boot-2010.09源代码进行修改
1. 打开顶层目录下的Makefile，并在ARM1176处添加下面红色部分内容

3. arch\arm\cpu\arm1176\s3c64xx\Makefile增加红色部分
COBJS-$(CONFIG_S3C6400) += cpu_init.o speed.o

6. 在board\samsung建立tiny6410的文件夹，并把smdk6400文件的所有文件复制过去
进入board\samsung\tiny6410\lowlevel_init.S

#define SROM_BW_REG __REG(ELFIN_SROM_BASE + 0x0)
#define SROM_BC0_REG __REG(ELFIN_SROM_BASE + 0x4)
#define SROM_BC1_REG __REG(ELFIN_SROM_BASE + 0x8)
#define SROM_BC2_REG __REG(ELFIN_SROM_BASE + 0xC)
#define SROM_BC3_REG __REG(ELFIN_SROM_BASE + 0x10)
#define SROM_BC4_REG __REG(ELFIN_SROM_BASE + 0x14)
#define SROM_BC5_REG __REG(ELFIN_SROM_BASE + 0x18)
#define INDEX_SROM_BW_REG 0x0
#define INDEX_SROM_BC0_REG 0x4
#define INDEX_SROM_BC1_REG 0x8
#define INDEX_SROM_BC2_REG 0xC
#define INDEX_SROM_BC3_REG 0x10
#define INDEX_SROM_BC4_REG 0x14
#define INDEX_SROM_BC5_REG 0x18
6. 在board\samsung建立tiny6410的文件夹，并把smdk6400文件的所有文件复制过去
进入board\samsung\tiny6410\lowlevel_init.S
/* LED on only #8 */
#if 0
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]
#endif
wakeup_reset:
/* Clearwakeup status register */
ldr r0, =(ELFIN_CLOCK_POWER_BASE +WAKEUP_STAT_OFFSET)
ldr r1, [r0]
str r1, [r0]
/* LED test */
#if 0
ldr r0, =ELFIN_GPIO_BASE
ldr r1, =0x3000
str r1, [r0, #GPNDAT_OFFSET]
#endif
上面两处红色部分屏蔽掉。
添加一个标志定义!defined(CONFIG_S3C6410)
/*#ifndef CONFIG_S3C6400*/
#if !defined(CONFIG_S3C6400) &&!defined(CONFIG_S3C6410)
ldr r1, [r0, #OTHERS_OFFSET]
bic r1, r1, #0xC0
orr r1, r1, #0x40
str r1, [r0, #OTHERS_OFFSET]
wait_for_async:
ldr r1, [r0, #OTHERS_OFFSET]
and r1, r1, #0xf00
cmp r1, #0x0
bne wait_for_async
#endif
下面同样也是
/* #elif !defined(CONFIG_S3C6400) */
#elif !defined(CONFIG_S3C6400)&&!defined(CONFIG_S3C6410)
/* According to661558um_S3C6400X_rev10.pdf 0x20 is reserved */
ldr r1, [r0, #OTHERS_OFFSET]
bic r1, r1, #0x20
str r1, [r0, #OTHERS_OFFSET]
#endif
mov pc,lr
board\samsung\Tiny6410\Makefile中添加
COBJS-y := smdk6400.o
COBJS-y := tiny6410.o
SOBJS := lowlevel_init.o
屏蔽掉下面三处红色部分：这个在smdk6400.c中
#include <common.h>
#include <netdev.h>
#include <asm/arch/s3c6400.h>
/*

*/
int board_init(void)
{

gd->bd->bi_arch_number= MACH_TYPE;
gd->bd->bi_boot_params= PHYS_SDRAM_1 + 0x100;
return 0;
}
修改如下部分：

printf("Board: TINY6410\n");
return 0;
}
#ifdef CONFIG_ENABLE_MMU

{
int rc = 0;
#ifdefined(CONFIG_DRIVER_DM9000)
rc= dm9000_initialize(bi);
#endif
return rc;
}
#endif
7. drivers\net\dm9000x.c增加红色部分

rxbyte = DM9000_inb(DM9000_DATA) & 0x03;
#if 1
u8 temp;
temp=DM9000_ior(DM9000_MRRH);
temp=DM9000_ior(DM9000_MRRL);
#endif
8. drivers\usb\host\ohci-hcd.c增加红色部分

defined(CONFIG_PCI_OHCI)|| \
defined(CONFIG_MPC5200) || \
defined(CONFIG_SYS_OHCI_USE_NPS)
9. include\configs\tiny6410.h（这个是smdk6400修改的吗）
//#define CONFIG_S3C6400 1 /* in a SAMSUNG S3C6400 SoC */
#define CONFIG_S3C6410 1 /* in a SAMSUNG S3C6400 SoC

#define CONFIG_S3C64XX 1 /* in a SAMSUNG S3C64XX Family */
#define CONFIG_SMDK6400 1 /* on a SAMSUNG SMDK6400 Board */
#define CONFIG_TINY6410 1
//#define MACH_TYPE 1270
#define MACH_TYPE 2520
把cs8900网卡换掉
#if 0
#define CONFIG_NET_MULTI
#define CONFIG_CS8900 /* we have a CS8900on-board */
#define CONFIG_CS8900_BASE 0x18800300

#define CONFIG_CMD_FAT
#define CONFIG_CMD_EXT2
#undef CONFIG_CMD_IMLS
/#define CONFIG_BOOTDELAY 3
//#define CONFIG_SYS_PROMPT "SMDK6400 # " /*Monitor Command Prompt */
改成你自己喜欢的提示字符这里是"TINY6410 # "
#define CONFIG_SYS_PROMPT "TINY6410 # " /* Monitor Command Prompt */
提高主频
Setting SYNC ASYNC
----------------------------------
667_133_66 X O
533_133_66 O O
400_133_66 X O
400_100_50 O O
**********************************/
#define CONFIG_CLK_667_133_66
//#define CONFIG_CLK_533_133_66
换掉这句
#define CONFIG_AMD_LV800
//#define CONFIG_SYS_FLASH_CFI 1 /* Use CFI parameters(needed?) */
#define CONFIG_SYS_NO_FLASH 1 /* Use CFI parameters (needed?) */
屏蔽下面的
#if 0
/* Use drivers/cfi_flash.c, even though the flash is notCFI-compliant */
#define CONFIG_FLASH_CFI_DRIVER 1
#define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_16BIT

Flash Write */
#endif
#define CONFIG_ENV_SIZE 0x4000 /* Total Size ofEnvironment Sector */
/*
* SMDK6400 board specific data
*/
这句也要改
//#define CONFIG_IDENT_STRING " for SMDK6400"
#define CONFIG_IDENT_STRING " for TINY6410"
10. include\common.h
添加红色部分
#ifdef CONFIG_4xx
ulong get_OPB_freq (void);
ulong get_PCI_freq (void);
#endif
#if defined(CONFIG_S3C24X0) || \
defined(CONFIG_LH7A40X) || \
defined(CONFIG_S3C6400) || \
defined(CONFIG_S3C6410) || \

11. 顶层的MAKEALL
