Ok, but it would be nice to see some runtime soc-type detection for gpiolib. 
s3c2410/s3c2440/s3c2442 doesn't differ too much (actually, they're same in 
gpiopart, s3c2410 lacks some gpiobanks that s3c244[0,2] have, and difference 
in pull-up/pull-down on s3c2440 and s3c2442).
I think it's not good to make artificial restrictions for building single 
binary kernel for these socs.
