First this is the wrong mailing list then. Its about U-Boot questions and you 
are asking about Linux I2C and SPI support. I suggest you move this over to 
linuxppc-dev.

To give you a quick answer to your questions: I2C is supported for 4xx in the 
current Linux kernel. SPI is still missing but I'm currently busy with 
integrating the 4xx SPI support and pushing it upstream. In a few days/weeks 
you should see something on the lists.

Best regards,
Stefan
