+Description:
+		The /sys/devices/soc directory contains a sub-directory for each
+		System-on-Chip (SoC) device on a running platform. Information
+		regarding each SoC can be obtained by reading sysfs files. This
+		functionality is only available if implemented by the platform.
+		This directory contains two kinds of attributes:
+			- Common attributes:
+				* machine: SoC machine name (e.g. Ux500).
+				* family: SoC family name (e.g. DB8500).
+			- SoC-specific attributes:
+				* SoC vendor declared
+                                * ST-Ericsson delcare the following
+                                  * soc_id: SoC serial number
+                                  * revision: SoC revision number
+				   * process: the way in which the chip was manufactured
+Users:
+		Any platform dependent user-space applications or profiling tools.
