Hi Mark and Shuming,
Thank you for the suggestion. I agree that it is better to use device
property to pass r0 and temperature through device property.
I am working on coreboot changes to parse data from VPD, and set device property
"rt1011,temperature_calib" and "realtek,r0_calib".
I think the patch in rt1011 driver will be much simpler once we have
that device property ready.
And there will be no machine driver change needed.

Thanks!
