It's really good to see work on this but I've got some concerns with the
approach being taken here.

This won't apply - this and several of the other machines are already

Please change this to use a platform data based approach rather than
these ifdefs: it's not a good approach for readability and it prevents
building multiple board drivers in one kernel which isn't good for
distributions. The s3c24xx_uda134x.c provides an example of how this
can be done. It may be more sensible to have a separate driver per
