Thanks for catching. Don't know why I missed those two boards.

But looking at the code (board/sandburst/common/ppc440gx_i2c.c), this seems to 
be a driver for the PPC4xx I2C bus 1. The common 4xx I2C driver 
(cpu/ppc4xx/i2c.c) is fully capable of handling I2C bus 0 *and* 1. Perhaps 
this was not the case when Travis wrote the board support. I would really like 
to drop this board specific code, as it doesn't seem necessary for me.

The board maintainer, Travis Sawyer, doesn't work for Sandburst (acquired by 
Broadcom some time ago?) any more. So we can't get his comments on this. Not 
sure what to do with those Sandburst boards now. They are not actively 
maintained any more. Perhaps we should remove them some time soon?

Wolfgang, what do you think? Should we try to carry such unmaintained boards 
on for ever?

Thanks.

Cheers,
Stefan
