I applied the following patches for this test:
mx6: add OTP bank1 registers thermal: imx_thermal: use CPU temperature grade for trip points imx: mx6: add display of CPU temperature grade in print_cpuinfo() imx: mx6: add get_cpu_temp_grade to obtain cpu temperature grade from OTP mx: mx6: display max cpu frequency in print_cpuinfo() imx: mx6: add get_cpu_speed_grade_hz func to return MHz speed grade from OTP The log info: " U-Boot 2015.07-rc1-00256-gec154cc (May 18 2015 - 09:00:57) CPU: Freescale i.MX6SX rev1.2 996 MHz (running at 792 MHz) CPU: at 39C Reset cause: POR Board: MX6SX SABRE SDB I2C: ready DRAM: 1 GiB PMIC: PFUZE100 ID=0x11 MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2 In: serial Out: serial Err: serial Net: FEC [PRIME] Hit any key to stop autoboot: 0 " >Thanks, > >Fabio Estevam Regards, Peng. -- _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
