2018-09-02mb/lenovo: dGPU power handling on T430, T530Evgeny Zinoviev
Enable dGPU power handling on Lenovo ThinkPad T430, T530 via PMH7 register 0x50. Although there's no Thinker-1 chip on these models according to schematics, dGPU power control via PMH7 works the same as on T420/T520, so they can be considered Thinker-1-compatible. It can be tested from linux userspace using util/pmh7tool. To turn dGPU power off: pmh7tool -c 0x50 7 pmh7tool -c 0x50 3 To turn it on: pmh7tool -s 0x50 3 pmh7tool -s 0x50 7 To check whether it is on (bash): reg=0x$(pmh7tool -r 0x50) echo "$(( (( reg & 0x08 )) >> 3 ))" or just `pmh7tool -b 0x50 3` with https://review.coreboot.org/#/c/coreboot/+/28388/ Tested on ThinkPad W530.

2018-06-04mb/lenovo/t430/devicetree: Add missing TPM entryPatrick Rudolph
Tested on Lenovo T430: The TPM is advertised through ACPI tables and the version can be read using tpm_version, tcsd and tpm_tis.

2017-09-11mb/lenovo/*/devicetree: Add BDC detection supportPatrick Rudolph
Add support for BDC detection, based on the schematics for each board. Support for boards without schematics needs further testing. Needs test on all boards.

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.
