Furquan Shaikh 3f0d64329c soc/intel/common/cse: Support RW update when stitching CSE binary
This change updates the STITCH_ME_BIN path to enable support for
including CSE RW update in CBFS. CSE_RW_FILE is set to either
CONFIG_SOC_INTEL_CSE_RW_FILE or CSE_BP2_BIN depending upon the
selection of STITCH_ME_BIN config.

Furquan Shaikh f888c682f8 soc/intel/alderlake: Enable support for CSE stitching
This change enables support for stitching of BP1 and BP2 partitions
for CSE. This currently mimics what Intel FIT tool does w.r.t. adding
different components to the different partitions.

BP1:
* Dummy components: DLMP, IFPP, SBDT, UFSP, UFSG, OEMP.
* Decomposed components from CSE FPT file: RBEP, MFTP.
* Input components: PMCP, IOMP, NPHY, TBTP, PCHC.

BP2:
* Dummy components: DLMP, IFPP, SBDT, UFSP, UFSG, OEMP, ISHP.
* Decomposed components from CSE FPT file: RBEP, FTPR, NFTP.
* Input components: PMCP, IOMP, NPHY, TBTP, PCHC, IUNP.

Furquan Shaikh 6ef863c5c4 soc/intel/common/cse: Add support for stitching CSE components
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.

Furquan Shaikh 3959aa6351 southbridge/intel/common: Add an option to allow stitching of CSE binary
In the following changes, CSE binary for some platforms will be
stitched at build time instead of adding a pre-built binary. This
change adds a new Kconfig `STITCH_ME_BIN` which allows mainboard to
select if it wants to stitch CSE binary instead of adding a pre-built
one. In this case, ME_BIN_PATH is not visible to user and instead
mainboard and/or SoC code is expected to provide the recipe for
stitching the CSE image.

* A symbol may only be declared inside or outside a choice.

The linter treats every occurence of a `config` entry as a symbol
declaration, even when it's just setting a default or adding selects.
This is not easy to fix as the symbol objects are not created first
and then added to the $symbols array when we know what kind of decla-
ration we have, but are created incrementally inside this global

Bernardo Perez Priego bc89bc6680 mb/intel/adlrvp_m: Enable retimer force power gpio
Retimer FORCE_PWR GPIO is a debug GPIO, that has to be set LOW, to allow Retimer LC Domain
to toggle during a switch from DP Alt to TBT Alt modes.
Contrary to DS specifying it may be left unconfigured, hence floating, there are instances
seen during boot, where it stays HIGH (adlmrvp) or LOW (adlprvp).
Hence configure it to LOW.

Branch=none
Bug=none
Test=Boot to OS, connect TBT dock which enumerates in DP Alt,
     Login, TBT dock enumerates in TBT Alt

Kyösti Mälkki 5791123356 cpu/intel/hyperthreading: Use initial LAPIC IDs
For older CPU models where CPUID leaf 0xb is not supported, use
initial LAPIC ID from CPUID instead of LAPIC register space to
to detect if logical CPU is a hyperthreading sibling. The one
in LAPIC space is more complex to read, and might not reflect
CPU topology as it can be modified in XAPIC mode.

Use the common ACPI code to reduce code duplication.

After this change, `PSS_MAX_ENTRIES` is honored correctly in P-state
table generation (as of commit c2540a9) and the number reduces from 10
to 7 entries.

Also, remnants of P_BLK support missed in CB:58096 will vanish.

Tested on google/fizz: no errors in dmesg, ACPI tables remain the same
(except PSS, as mentioned above).

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.

it overrides the hardware PM Timer. Thus, only enable emulation

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.

platforms, in order to transition handling of the PM timer from FSP to

For SKL and CNL, this temporarly redundantly disables the PM Timer,
since FSP does that, too. This redundancy is resolved in the follow-up.
