+  Files in here are either common to all the s3c24xx family,
+  or are common to only some of them with names to indicate this
+  status. The files that are not common to all are generally named

+  As an example, initially s3c244x would cover s3c2440 and s3c2442, but
+  with the s3c2443 which does not share many of the same drivers in
+  this directory, the name becomes invalid. We stick to s3c2440-<x>
+  to indicate a driver that is s3c2440 and s3c2442 compatible.
+
+  This does mean that to find the status of any given SoC, a number
+  of directories may need to be searched.
