ARM: ux500: export System-on-Chip information ux500 via sysfs
Here we make use of the new System-On-Chip bus driver to export vital SoC information out to userspace via sysfs. This patch provides a data structure of strings to populate the base nodes found in: /sys/devices/soc[0|1|2|...]/[family|machine|revision|soc_id]. It also adds one more node as requested by ST-Ericsson. 'process' depicts the way in which the silicon was manufactured.
