2021-01-11{soc,vc,mb}/intel: Drop support for Cannon Lake SoCFelix Singer
Drop the support for the Intel Cannon Lake SoC for various reasons: * Most people can't use coreboot on Cannon Lake, since the required FSP binaries aren't publicly available. Given that FSP binaries for several newer platforms have been released, it's very unlikely that Cannon Lake FSP will ever be released. * It seems there is no interest in this, since the reference mainboard is the only available mainboard in tree. Also, remove the related reference mainboard intel/cannonlake_rvp and its FSP headers in intel/fsp2_0/cannonlake.

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>

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.

2018-12-13cpuid: Add helper function for cpuid(1) functionsSubrata Banik
This patch introduces 3 helper function for cpuid(1) : 1. cpu_get_cpuid() -> to get processor id (from cpuid.eax) 2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx) 3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx) Above 3 helper functions are targeted to replace majority of cpuid(1) references.

2018-10-26soc/intel/cannonlake: Add back PM TIMER EMULATIONLijian Zhao
ACPI PM timer emulation will be added back as default FSP stops TCO count for power saving, which will also stop ACPI PM timer within PCH. CPU PM TIMER EMULATION will help UEFI payload pass, instead of endless loop wait for ACPI PM timer counter to increase. BUG=N/A TEST=Build and boot up fine with whiskey lake rvp board into UEFI shell.

2017-09-11cpu/x86/mp_init: remove adjust_cpu_apic_entry()Aaron Durbin
The original purpose of adjust_cpu_apic_entry() was to set up an APIC map. That map was effectively only used for mapping *default* APIC id to CPU number in the SMM handler. The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.
