2019-07-19sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supportedPatrick Rudolph
The processor P_BLK doesn't support throttling. This behaviour could be emulated with SMM, but instead just update the FADT to indicate no support for legacy I/O based throttling using P_CNT. We have _PTC defined in SSDT, which should be used in favour of P_CNT by ACPI aware OS, so this change has no effect on modern OS. Drop all occurences of p_cnt_throttling_supported and update autoport to not generate it any more.

2017-08-10nb/intel/sandybridge/raminit: Add Kconfig option for fusesPatrick Rudolph
Add a new Kconfig option to ignore memory fuses that limit the maximum DRAM frequency to be used. The option is disabled by default and should only enabled by experienced users as it might decrease system stability or prevent a successful RAM training. Remove conflicting devicetree settings.

2017-08-10mb/lenovo/t*00/romstage: Switch to new hybrid driverPatrick Rudolph
Get rid of old hybrid graphics driver and use the new one. 1. Disable IGD and PEG in early romstage. The PEG port will get disabled on devices that do not have a discrete GPU. The power savings are around ~1Watt. The disabled IGD does no longer waste GFX stolen memory. 2. Get rid of PCI driver The Nvidia GPU can be handled by the generic PCI driver and allows to use the ACPI _ROM generator for Switchable graphics. 3. Settings are stored in devicetree. One driver for all Lenovo hybrid graphics capable devices. 4. Add support for Thinker1 GPU power handling. Only boards that do use reference design 2012 are known to be supported. Needs test on boards that do you use reference design 2013. Should reduce idle power consumption when using IGD by ~5Watt. Tested on Lenovo T430 without DGPU. PEG port is disabled. Needs test on all devices.

2016-06-20nb/intel/sandybridge/raminit: Allow 933Mhz on Lenovo devicesPatrick Rudolph
Set max_mem_clock_mhz in devicetree to 933Mhz. Allows to run the memory at up to DDR3-1866. The same frequency was allowed within the first vendor bios, but Lenovo than decided to limit it to DDR3-1333. Tested on Lenovo T520 and DDR3-1600 DIMM (RMT3170eb86e9w16). The RAM is now running at DDR3-1600 instead of DDR3-1333. This gives about 4% performance increase in glmark2 using the Intel GPU.
