This would help to print the SoC family number, with associated temparature, clock and reason for reset etc. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- arch/arm/mach-rockchip/Makefile | 1 + arch/arm/mach-rockchip/cpu-info.c | 16 ++++++++++++++++ 2 files changed, 17 insertions(+) create mode 100644 arch/arm/mach-rockchip/cpu-info.c
