Hi All,
I'm trying to build u-boot with i2c support for  a mba2440 board. U-boot version is mba2440-uboot1.1.1. 
In mba2440.h config file i have selected the i2c commands :

#define CONFIG_COMMANDS \
                        (CONFIG_CMD_DFL         | \
                        CFG_CMD_CACHE         | \
                        CFG_CMD_NAND         | \
                        CFG_CMD_PING         | \
                        /*CFG_CMD_EEPROM |*/ \
                        CFG_CMD_I2C         | \
                        /*CFG_CMD_USB                  |*/ \
                        CFG_CMD_REGINFO  | \
                        CFG_CMD_DATE         | \
                        CFG_CMD_FAT                 | \
                        CFG_CMD_MMC                 | \
                        CFG_CMD_NET                 | \
                        CFG_CMD_ELF)

I get the following error when trying to build:

you use a very old version of u-boot, you should update to current
version.

As the error message says, some symbols are missing ... if you want to
use i2c, you must enable through a CONFIG option, which i2c driver you
want to use on your hardware. I cannot help you more here, because I
do not know anything about your board.

Yep!

Heiko

Actually i got that u-boot version from our vendor. They ported u-boot  
to make it work  with the mba2440 board(s3c2440 processor) they are  
selling,  but they didn't submit it as patch, i guess that's why i  
have all files for that board and you don't in mainline.
I've downloaded u-boot-2011-12 and tried porting it to the mba 2440  
hardware by adding configuration options and files but i had errors  
when compiling with arm-linux-gcc cross compiler. I think i'll just  
try to fix the missing symbols problem using the old u-boot version
Regards
Yannick
