defined when you define CONFIG_HARD_I2C or CONFIG_SOFT_I2C.
In both cases you will need to define CFG_I2C_SPEED

Now, the u-boot i2c code for the mpc8xx (cpu/mpc8xx/i2c.c)
sets the cpu up as a master node and so its address should
therefore be cleared to 0 (See, eg, MPC823e User's Manual

If you use the software i2c interface (CONFIG_SOFT_I2C)
then the following macros need to be defined (examples are
eg: #define I2C_SCL(bit) \
if(bit) immr->im_cpm.cp_pbdat |= PB_SCL; \

I2C_DELAY
This delay is invoked four times per clock cycle so this
controls the rate of data transfer. The data rate thus
is 1 / (I2C_DELAY * 4). Often defined to be something
