移植U-Boot-2009.08到友善之臂mini2440（六）

移植U-Boot-2009.08到友善之臂mini2440（六）

(1) include/configs/mini2440.h添加对2440的宏定义：

#define CONFIG_ARM920T          1       /* This is an ARM920T Core      */

//#define       CONFIG_S3C2410          1      /* in a SAMSUNG S3C2410 SoC     */

//#define CONFIG_SBC2410X          1      /* on a friendly-arm SBC-2410X Board  */

添加对2440、mini2440、LED的支持

#define CONFIG_S3C2440          1       /* in a SAMSUNG S3C2410 SoC     */

#define CONFIG_MINI2440         1       /* on a friendly-arm mini2440 Board  */

#define CONFIG_MINI2440_LED     1  /* Use the LED on Board */

#define CONFIG_S3C2440_NAND_BOOT       1

#define CONFIG_S3C2410_NAND_SKIP_BAD   1

(2)修改网卡的宏定义，注释掉CS8900的部分，添加对DM9000的支持

 

删除对cs8900的支持：

/* Hardware drivers*/

#if 0

#define CONFIG_DRIVER_CS8900    1       /* we have a CS8900 on-board */

#define CS8900_BASE             0x19000300

#define CS8900_BUS16            1 /* the Linux driver does accesses as shorts */

#endif

添加对DM9000的支持：

#define CONFIG_DRIVER_DM9000                  1

#define CONFIG_DM9000_USE_16BIT               1

#define CONFIG_DM9000_BASE                    0x20000300

#define DM9000_IO                             0x20000300

#define DM9000_DATA                           0x20000304

#define CONFIG_DM9000_NO_SROM           1

#undef CONFIG_DM9000_DEBUG

#define CONFIG_NET_MULTI                1

 

添加对nand命令的支持：

#define CONFIG_CMD_ASKENV

#define CONFIG_CMD_CACHE

#define CONFIG_CMD_DATE

#define CONFIG_CMD_DHCP

#define CONFIG_CMD_ELF

#define CONFIG_CMD_PING

#define CONFIG_CMD_NAND

//#define CONFIG_CMD_REGINFO

//#define CONFIG_CMD_FAT

 

#define CONFIG_BOOTARGS         "noinitrd root=/dev/nfs rw nfsroot=202.204.53.32:/opt/mini2440/nfs  ip=202.204.53.33: 202.204.53.32::255.255.255.0 console=ttySAC0,115200 init=/linuxrc mem=64M"

#define CONFIG_ETHADDR          08:00:3e:26:0a:5b

#define CONFIG_NETMASK          255.255.255.0

#define CONFIG_IPADDR           202.204.53.182

#define CONFIG_SERVERIP         202.204.53.181

#define CONFIG_GATEWAYIP        202.204.53.1

/*#define CONFIG_BOOTFILE       "elinos-lart" */

#define CONFIG_BOOTCOMMAND      " tftp 0x30008000 zImage.img;bootm"

#define CONFIG_OVERWRITE_ETHADDR_ONCE

#define  CONFIG_EXTRA_ENV_SETTINGS                                       \

       "stdin=serial\0"                                        \

       "stdout=serial\0"                                       \

       "stderr=serial\0"

 

修改载入内存地址：

#define CONFIG_SYS_LOAD_ADDR         0x30008000      /* default load address */

#define CONFIG_ENV_ADDR         (CONFIG_SYS_FLASH_BASE + 0x060000) /* addr of environment */

 

#define CONFIG_ENV_IS_IN_NAND 1

#define CONFIG_ENV_OFFSET               0X60000

#define CONFIG_ENV_SIZE                 0x20000 /* Total Size of Environment Sector */

 

#define MTDPARTS_DEFAULT "mtdparts=nandflash0:384k(bootloader)," \

                                              "128k(params)," \

                                              "5m(kernel)," \

                                              "-(root)"
