Implementation for setup_lapic() did two things -- call enable_lapic() and virtual_wire_mode_init(). In PARALLEL_MP case enable_lapic() was redundant as it was already executed prior to initialize_cpu() call. For the !PARALLEL_MP case enable_lapic() is added to AP CPUs.

2021-10-22cpu/x86/mp_init: move printing of failure message into mp_init_with_smmFelix Held
Each CPU/SoC checks the return value of the mp_init_with_smm and prints the same error message if it wasn't successful, so move this check and printk to mp_init_with_smm. For this the original mp_init_with_smm function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm function is created which then calls do_mp_init_with_smm, prints the error if it didn't return CB_SUCCESS and passes the return value of do_mp_init_with_smm to its caller. Since no CPU/SoC code handles a mp_init_with_smm failure apart from printing a message, also add a comment at the mp_init_with_smm call sites that the code might want to handle a failure.

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.

2020-03-28soc/intel/jasperlake: Add Jasper Lake SoC supportAamir Bohra
This is a copy patch from Tiger Lake SoC code. The only changes done on top of copy is changing below configs: 1. SOC_INTEL_TIGERLAKE -> SOC_INTEL_TIGERLAKE_COPY 2. SOC_INTEL_JASPERLAKE -> SOC_INTEL_JASPERLAKE_COPY 3. SOC_INTEL_TIGERLAKE_BASE -> SOC_INTEL_TIGERLAKE_BASE_COPY We started with initial assumption that JSL and TGL can co-exist. But now we see the SoC code in Tiger Lake is relying on too many compile-time directives to make two SoCs co-exist. Some of the differences are listed below: -> Kconfig: Multiple Kconfig options using if SOC_INTEL_{TIGERLAKE/JASPERLAKE} -> GPIO: GPIO communities have their own differences. This requires conditional checks in gpio.asl, gpio.c, gpio*.h, pmc.h and gpio.asl -> PCI IRQs: Set up differently for JSL and TGL -> PCIe: Number of Root ports differ. -> eMMC/SD: Only supported on JSL. -> USB: Number of USB port are different for JSL and TGL. -> Memory configuration parameters are different for JSL and TGL. -> FSP parameters for JSL and TGL are different. The split of JSL and TGL SoC code is planned as below: 1. Copy Tiger Lake SoC code as is, and change SoC Kconfig to avoid conflicts with current mainboard builds. 2. Clean up TGL code out of copy patch done in step 1. Make it JSL only code. The SoC config still kept as SOC_INTEL_JASPERLAKE_COPY. 3. Change JSL SOC Kconfig from SOC_INTEL_JASPERLAKE_COPY to SOC_INTEL_JASPERLAKE, dedede and jasperlake_rvp boards can bind to SoC code from soc/intel/jasperlake. This step establishes Jasper Lake as a separate SoC. 4. Clean up current JSL code from TGL code. This step establishes Tiger Lake as a separate SoC.
