The first patch exactly makes needed changes for ARM architecture and adds a common approach to show SoC name. Second patch uses this approach for TI OMAP4 SoCs (as live example). Why we need it? First - the /proc/cpuinfo becomes more informative. Added new line "SoC name" in the "cpuinfo" output for system on a chip name. It is placed between CPU information and machine information, so the file structure looks gracefully ('CPU-SoC-Hardware' instead of 'CPU-Hardware' that we have now) Second - this information may be used by userspace for different purposes (as example - OMAP4460 and OMAP4470 SoCs have different graphics accelerators, and userspace may want to know what libraries to use and what module to insert if the graphics drivers are built as modules) Looks like there were few attempts to do similar changes to cpuinfo without any luck (had stuck on review) so this functionality is still not in the kernel yet. In this patch series the update to cpuinfo is very short (10 lines) and easy. Comments are welcome as usual -------------------------------------------------- v3: Addressed comments from Nishanth (changed 'SoC name' field for OMAP - now it shows only SoC name without additional info) Updated commit messages. Updated this cover letter with additional information -------------------------------------------------- v2: Addressed comments from Russel (changed 'CPU name' > 'SoC name') Updatet commit messages.
