Yes, this would be best. But if you can map the I2C pins via pin multiplexing 
to some GPIO pins, you could use the existing soft_i2c driver.

I have no idea, since I don't have any infos about your I2C controller. I 
don't know if it is similar to any of the supported controllers. So you need 
to check this yourself.

From the PPC4xx user manuals. For example the PPC440EPx. You can download 
those manual from the AppliedMicro (AMCC) web site.
