Firstly, doing stuff if the driver is enabled or not is not a good idea,
as it means re-installing the kernel if you then go and build the driver
as a module at a later date.

Two, since I guess that the IDE gpio setup should be the same across all
s3c6410 based systems, then you should look at supplying a standard
platform data that the board can use instead of having to duplicate this
across all the boards.

Ok. I will remove the conditional compilation and move the platform
data from SMDK board file. Since the IDE driver is not accepted, these
patches will be updated and resent again with the libata based driver.

Thanks Ben for reviewing the patches.

Thomas.
