Currently, reading /proc/cpuinfo provides userspace with CPU ID of the CPU carrying out the read from the file. Userspace using this information may decide what module to load or how to configure some specific (and processor-depended) settings or so. However, since really different SoCs can share same ARM core, this information currently is not so useful. For example, TI OMAP4460 and OMAP4470 SoCs show the same information in the /proc/cpuinfo whereas they are different. Since in most cases ARM CPU is a part of some system on a chip (SoC), the "cpuinfo" file looks like exactly that place, where this information have to be displayed. So 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) Example: / # cat proc/cpuinfo [...] CPU variant : 0x2 CPU part : 0xc09 CPU revision : 10 SoC name : OMAP4470 ES1.0 HS Hardware : OMAP4 Blaze Tablet Revision : 20edb4 [...] Signed-off-by: Ruslan Bilovol <ruslan.bilovol@ti.com> --- arch/arm/include/asm/setup.h | 1 + arch/arm/kernel/setup.c | 9 +++++++++ 2 files changed, 10 insertions(+)
