this is a driver for ST-Ericsson u8500 board(Snowball), with a ARM core inside. so you should compile like this: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- u8500_defconfig make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage On 15 November 2012 17:13, Zhang Rui <rui.zhang@xxxxxxxxx> wrote: > On Thu, 2012-11-15 at 16:32 +0800, Hongbo Zhang wrote: >> On 15 November 2012 16:13, Zhang Rui <rui.zhang@xxxxxxxxx> wrote: >> > On Fri, 2012-11-09 at 19:29 +0800, hongbo.zhang wrote: >> >> From: "hongbo.zhang" <hongbo.zhang@xxxxxxxxxx> >> >> >> >> This driver is based on the thermal management framework in thermal_sys.c.
