PS5, Line 230: 				## Fan Performance Control (Percent, Speed, Noise, Power)
Please see the previous discussion in https://chrome-internal-review.googlesource.com/c/chromeos/project/nissa/cra... The proposal from the quanta thermal team was:

- Fan controlled by EC only, based on `FAN` fw_config. No fan table in coreboot.
- Other DPTF settings in coreboot selected by `THERMAL_SOLUTION` fw_config.

So I don't expect to see a fan table in coreboot. Since there are 6W+fan SKUs, we can't select the fan table based on `THERMAL_SOLUTION` only. If we do need a fan table in coreboot, we'll have to change the fw_config setup.
