The init microcode knows very well which calibrations are required and sends us results for those that are. Consequently, we can just send all of those to the RT uCode again. The problem with having the driver know about this is that it is a uCode feature, not a hardware feature so the config is completely unsuitable. The only thing we need to check is whether the device needs crystal calibration or not, add a new parameter to the configuration for that. This makes new uCode work on 6000 series devices.
