It is not a normal AMCC PPC4xx, its a customized PPC4xx chip. so I2C code wont work for me as it is.
i will have to map my register with i2c register used by u-boot.
Now i have downloaded latest u-boot version(Jan 25 2010 12:37 Link u-boot-latest.tar.bz2 -> u-boot-2009.11.1.tar.bz2) from ftp.
still ppc4xx_i2c structure i could not found.

So is this a "normal" AMCC PPC4xx (e.g. 440GX...) or a custom PPC4xx chip? If it's a common 4xx, then the normal PPC4xx I2C code should just work for you as well.
U-boot version that i am using is u-boot-2009.11.
That is before the restructuring. For new work please use the latest version from the git repository.
Here i am searching for the ppc4xx_i2c structure but not able to get it. on the other hand i have seen the i2c register macros used in i2c_transfer call.
Again, 2009-11 is already outdated. I reworked the I2C stuff in the meantime. Try the latest version and take a look at:
cpu/ppc4xx/i2c.c include/4xx_i2c.h
Cheers, Stefan
