This series does not apply cleanly any more on u-boot-i2c. I would have to
post an updated version.
In my opinion, It would be better that this series to be disregarded and the
new board Trats2 goes through the Samsung tree (it's been already tested).
Then later I should post new patches to adapt s3c24x0 i2c driver.
