2021-10-22soc/intel/denverton_ns: use mp_cpu_bus_initFelix Held
After adding the functionality to add a bus/link on the CPU cluster device in mp_cpu_bus_init if it is missing due to no LAPIC device being present in the devicetree below the CPU cluster device, we can use mp_cpu_bus_init as init function in cpu_bus_ops and implement mp_init_cpus.

2021-10-22arch/x86/ioapic: Select IOAPIC with SMPKyösti Mälkki
For coreboot proper, I/O APIC programming is not really required, except for the APIC ID field. We generally do not guard the related set_ioapic_id() or setup_ioapic() calls with CONFIG(IOAPIC). In practice it's something one cannot leave unselected, but maintain the Kconfig for the time being.

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.

2021-10-19soc/intel/common/cse: Add support for stitching CSE componentsFurquan Shaikh
This change adds support for allowing mainboards to stitch CSE components during build time instead of adding a pre-built CSE binary. Several Kconfig options are added to allow mainboard to provide the file names for different CSE region components. This makes use of the newly added cse_serger and cse_fpt tools to create following partitions: 1. BP1 - RO 2. BP2 - RW 3. Layout In addition to this, it accepts CSE data partition as an input using Kconfig CSE_DATA_FILE. All these partitions are then assembled together as per the following mainboard FMAP regions: 1. BP1(RO) : CSE_RO 2. BP2(RW) : CSE_RW 3. Layout : CSE_LAYOUT 4. Data : CSE_DATA Finally, it generates the target $(OBJ_ME_BIN) which is used to put together the binary in final coreboot.rom image. Several helper functions are added to soc/intel/Makefile.inc to allow SoCs to define which components use: 1. Decomposed files: Files decomposed from Intel release CSE binary in FPT format. 2. Input files: Mainboard provided input files using corresponding Kconfigs. 3. Dummy: Components that are required to have dummy entries in BPDT header. These helpers are added to soc/intel/Makefile.inc to ensure that the functions are defined by the time the invocations are encountered in SoC Makefile.inc.

2021-10-17soc/intel: transition full control over PM Timer from FSP to corebootMichael Niewöhner
Set `EnableTcoTimer=1` in order to keep FSP from 1) enabling ACPI Timer emulation in uCode. 2) disabling the PM ACPI Timer. Both actions are now done in coreboot. `EnableTcoTimer=1` makes FSP skip these steps in any possible case including `SkipMpInit=0`, `SkipMpInit=1`, use of the MP PPI or FSP Multiphase Init. This way full control is left to coreboot.

This is done to bring SKL, CNL, DNV in line with the other platforms, in order to transition handling of the PM timer from FSP to coreboot in the follow-up changes. For SKL and CNL, this temporarly redundantly disables the PM Timer, since FSP does that, too. This redundancy is resolved in the follow-up.

2021-10-13soc/amd/common: Add support to read and set SPI speeds from verstageKarthikeyan Ramasubramanian
Currently all SPI speed configurations are done through EFS at build time. There is a need to apply SPI speed overrides at run-time - eg. based on board version after assessing the signal integrity. This override configuration can be carried out by PSP verstage and bootblock. Export the APIs to set and read SPI speeds from both PSP verstage and bootblock.
