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.

That is before the restructuring. For new work please use the latest version
from the git repository.

Again, 2009-11 is already outdated.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
