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>

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.
