Before add CONFIG_SYS_MALLOC_F and CONFIG_SYS_MALLOC_F_LEN, uboot will complains "CPU: Temperature: Can't find sensor device". This is because DM and DM_THERMAL are enabled, but SYS_MALLOC_F is not configured.
After applying this patch, uboot can correctly detect the temperature. " U-Boot 2015.04-rc2-00146-g48b6e30-dirty (Mar 09 2015 - 13:04:36)
CPU: Freescale i.MX6DL rev1.1 at 792 MHz CPU: Temperature 44 C "
