soc/intel/common/smbus: Add support for Apollo Lake SoC
Previously, SMBUS support was not required for Apollo Lake, since the SPD was read inside FSP-M, during memory initialization. However, the Kontron mAL-10 COMe module contains Nuvoton HWM chip that is connected to the processor via SMBUS. This patch adds SMBUS common driver support for Apollo Lake to initialize this HWM. TEST = After loading the nct7802 module on the Kontron mAL-10 with Linux OS, we can read the hwm registers, see temperature and fan speed: coretemp-isa-0000 Adapter: ISA adapter Package id 0: +52.0°C (high = +110.0°C, crit = +110.0°C) Core 0: +52.0°C (high = +110.0°C, crit = +110.0°C) Core 1: +52.0°C (high = +110.0°C, crit = +110.0°C) Core 2: +53.0°C (high = +110.0°C, crit = +110.0°C) Core 3: +53.0°C (high = +110.0°C, crit = +110.0°C) nct7802-i2c-0-2e Adapter: SMBus CMI adapter cmi in0: +3.35 V (min = +0.00 V, max = +4.09 V) in1: +1.92 V in3: +1.21 V (min = +0.00 V, max = +2.05 V) in4: +1.68 V (min = +0.00 V, max = +2.05 V) fan1: 0 RPM (min = 0 RPM) fan2: 1729 RPM (min = 0 RPM) fan3: 0 RPM (min = 0 RPM) temp1: +53.5°C (low = +0.0°C, high = +85.0°C) (crit = +100.0°C) sensor = thermistor temp4: +53.0°C (low = +0.0°C, high = +85.0°C) (crit = +100.0°C) temp6: +0.0°C Change-Id: I408ef84ede27a45fb057e22b2757fa6e66277ddd Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/44475 Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Werner Zeh <werner.zeh@siemens.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
