2021-05-07soc/intel/{adl,tgl,jsl}: Enable power button smi after BS_CHIPS_EXITKane Chen
On tgl, we noticed system hang if a shutdown is triggered before fsps. The dut is unable to shutdown properly due to tcss is stuck before tcss_init in fsps. This change enable power button smi on jsl, tgl, adl after fsps. it can also prevent a shutdown failure due to lack of fsps init on certain ip. BUG=b:186194102, b:186815114 TEST=Power on the system and pressing power button repeatedly doesn't cause the system hang during shutdown.

ACPI S3 is a global state and it is no longer needed to pass it as a parameter.

2020-10-28soc/intel: deduplicate ACPI timer emulationMichael Niewöhner
The code for enabling ACPI timer emulation is the same for the SoCs SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to common code. APL differs in not having the delay settings. However, the bits are marked as "spare" and BWG mentions there are no "reserved bit checks done". Thus, we can write them unconditionally without any effect. Note: The ACPI timer emulation can only be used by SoCs with microcode supporting CTC (Common Timer Copy) / ACPI timer emulation.

2020-10-26soc/intel: drop unneeded ISST configuration codeMichael Niewöhner
The code configuring ISST (Intel SpeedShift Technology) sets the ISST capability bits in CPUID.06H:EAX. It does *not* activate HWP (Hardware P-States), which shall be done by the OS only. Since the capability is enabled by default (opt-out), there is nothing to do for us in the enabled-case. Practically speaking, there is no value at all in disabling the capability, since one can configure the OS to not enable HWP if that is desired. The two other bits for EPP and HWP interrupt that were set by the code are not set anymore, too. It was tested, on three platforms so far (CML-U, KBL-H, SKL-U), that these are set as well by default in the MSRs reset value (0x1cc0). To reduce complexity and duplicated code without actual benefit, this code gets dropped. The remaining dt option will be dropped in CB:46462. Test: Linux on Supermicro X11SSM-F detects and enables HWP: [ 0.415017] intel_pstate: HWP enabled Change-Id: I952720cf1de78b00b1bf749f10e9c0acd6ecb6b7 Signed-off-by: Michael Niewöhner <foss@mniewoehner.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/46460 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Felix Singer <felixsinger@posteo.net> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

Move a whole bunch of copy-pasta code from soc/intel/{bdw,skl,cnl,icl, tgl,ehl,jsl,adl} and cpu/intel/{hsw,model_*} to cpu/intel/common. This change just moves the code. Rework is done in CB:46588.
