2022-02-05cpu/x86/lapic: Move LAPIC configuration to MP initKyösti Mälkki
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.

2022-02-04soc/intel/{adl, common}: Add routines into CSE IA-common codeSubrata Banik
This patch adds routines to keep CSE and other HECI devices into the lower power device state (AKA D0I3). - cse_set_to_d0i3 => Set CSE device state to D0I3 - heci_set_to_d0i3 => Function sets D0I3 for all HECI devices Additionally, creates a config `MAX_HECI_DEVICES` to pass the HECI device count info from SoC layer to common CSE block.

2021-10-29soc/intel/apollolake: Fix BUG-message when checking for XDCI deviceWerner Zeh
The current check for XDCI enabled uses a static device path to an internal PCI device at a very late point in the boot flow. At this time the devicetree has been processed and disabled devices have been already removed. If this device (00:15.1, XDCI) is disabled in devicetree this will trigger the message 'BUG: check_xdci_enable requests hidden 00:15.1' in the log. This looks weird and is wrong since it is not a bug to disable this device when it is not needed. To avoid this look up the devicetree by a tree walk instead of using a static value for the devicetree.

With using a Kconfig option to add the x86 LAPIC support code to the build, there's no need for adding the corresponding directory to subdirs in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added (cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding MTRR code selection patch and having verified that all platforms added the MTRR code on that patch shows that soc/example/min86 and soc/intel/quark are the only platforms that don't end up selecting the LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y which gets overridden to n in the Kconfig of the two SoCs mentioned above.

All x86-based CPUs and SoCs in the coreboot tree end up including the Makefile in cpu/x86/mtrr, so include this directly in the Makefile in cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is selected be default could be added and the new CPU/SoC without MTRR support can override this option that then will be used in the Makefile to guard adding the Makefile from the cpu/x86/mtrr sub-directory. In cpu/intel all models except model 2065X and 206AX are selcted by a socket and rely on the socket's Makefile.inc to add x86/mtrr to the subdirs, so those models don't add x86/mtrr themselves. The Intel Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the subdirs. The Intel Xeon SP SoC directory contains two sub-folders for different versions or generations which both add x86/mtrr to the subdirs in their Makefiles.

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.

Apollo Lake and Gemini Lake do not have a hardware PM ACPI timer but only uCode PM Timer emulation. Add a Kconfig `NO_PM_ACPI_TIMER` denoting SoCs without PM Timer and make it mutually exclusive with the Kconfig `USE_PM_ACPI_TIMER`. This is partly redundant to `PM_ACPI_TIMER_OPTIONAL`, which will be dropped in the follow-up change, though.

Refer to detailed description below to understand the motivation behind this change. An advanced GPIO PM capabilities has been introduced since CNP PCH, refer to 'include/intelblock/gpio.h' for detailed GPIO PM bit definitions. Now with TGP PCH, additional bits are defined in the MISCCFG register for GPIO PM control. This results in different SoCs supporting different number of bits. The bits defined in earlier platforms (CNL, CML, ICL) are present on TGL, JSL and ADL too.

2021-03-05soc/intel/apollolake: Add `GPE0_STS_BIT` macroAngel Pons
The datasheet indicates that this bit is reserved. However, subsequent patches need to use this macro in common code, or else builds fail. To iron out this difference, mask out the bit in `soc_get_smi_status`, so that common code always sees it as zero. Finally, add an entry for the bit in `smi_sts_bits` for debugging usage, noting that it is reserved.
