Matt DeVillier a358f2b4f7 mb/google/brya: Compile gpio.c in SMM when needed
Without gpio.c compiled in, SMMSTORE will fail to initialize and hang.
Add a conditional inclusion so gpio.c is compiled in SMM when SMMSTORE
is selected.

TEST=build/boot google/banshee with SMMSTORE support enabled

Arthur Heymans fd4e676bb3 Revert "cbfstool/default-x86.fmd: Rename BIOS -> SI_BIOS"
This reverts commit 89b4f69746.

SI_BIOS is mostly used to indicate the BIOS region in Intel IFD. Not all
platforms are Intel platforms with an IFD, so revert this change. Also
tooling often depends on names not changing so renaming things should
not be done lightly. The default region should also be in sync with
non-x86 and made systematic across the tree.

Sridhar Siricilla 7301cfac60 soc/intel/common: Order the different types of cores based on APIC IDs
Currently coreboot presents the BSP core first, then efficient cores and
Performance cores as indicated below:

```
/sys/devices/system/cpu/cpu0/topology/thread_siblings_list:0-1
/sys/devices/system/cpu/cpu4/topology/thread_siblings_list:4
/sys/devices/system/cpu/cpu5/topology/thread_siblings_list:5
/sys/devices/system/cpu/cpu6/topology/thread_siblings_list:6
/sys/devices/system/cpu/cpu7/topology/thread_siblings_list:7
/sys/devices/system/cpu/cpu1/topology/thread_siblings_list:0-1
/sys/devices/system/cpu/cpu2/topology/thread_siblings_list:2-3
/sys/devices/system/cpu/cpu3/topology/thread_siblings_list:2-3

```
Existing code presents mix of different cores to OS and causes CPU load
balancing and power/performance impact. So, the patch fixes this
disorder by ordering the Performance cores first, compute die efficient
cores next, and finally SOC efficient cores if they are present. This
is done to run the media applications in a power efficient manner,
please refer the ChromeOS patches for details:
https://chromium-review.googlesource.com/c/chromiumos/platform2/+/3963893

Jeremy Compostella 1d79188dc5 soc/intel/cmn/cse: Handle EOP completion asynchronously
coreboot supports three instances of sending EOP:
1. At CSE `.final' device operation
2. Early as with Alder Lake in chip_operations.init if
   `SOC_INTEL_CSE_SEND_EOP_EARLY' is selected
3. At BS_PAYLOAD_BOOT as designed for Meteor Lake if
   `SOC_INTEL_CSE_SEND_EOP_LATE' is selected

Currently, Alder Lake uses #3 as it results in better and more stable
boot time. However, what would deliver even better result is to not
actively wait for CSE completion.

This patch introduces a new `SOC_INTEL_CSE_SEND_EOP_ASYNC' Kconfig
which split the action of sending EOP request and receiving EOP
completion response from the CSE.

This patch used in conjunction with #1 can significantly
improves the overall boot time on a Raptor Lake design. For example
`SOC_INTEL_CSE_SEND_EOP_ASYNC' on a skolas board can deliver up to 36
ms boot time improvement as illustrated below.

   |    #     | Late EOP | Async EOP |
   |----------+----------+-----------|
   |    1     | 1020.052 |   971.272 |
   |    2     | 1015.911 |   971.821 |
   |    3     | 1038.415 |  1021.841 |
   |    4     | 1020.657 |   993.751 |
   |    5     | 1065.128 |  1020.951 |
   |    6     | 1037.859 |  1023.326 |
   |    7     | 1042.010 |   984.412 |
   |----------+----------+-----------|
   | Mean     |  1034.29 |    998.20 |
   | Variance |   4.76 % |    5.21 % |

The improvement is not stable but comparing coreboot and FSP
performance timestamps demonstrate that the slowness is caused by a
lower memory frequency (SaGv point) at early boot which is not an
issue addressed by this patch.

We also observe some improvement on an Alder Lake design. For example,
the same configuration on a kano board can deliver up to 10 ms boot time
improvement as illustrated below.

   |        # | Late EOP | Async EOP |
   |----------+----------+-----------|
   |        0 | 1067.719 |  1050.106 |
   |        1 | 1058.263 |  1056.836 |
   |        2 | 1064.091 |  1056.709 |
   |        3 | 1068.614 |  1055.042 |
   |        4 | 1065.749 |  1056.732 |
   |        5 | 1069.838 |  1057.846 |
   |        6 | 1066.897 |  1053.548 |
   |        7 | 1060.850 |  1051.911 |
   |----------+----------+-----------|
   |     Mean |  1065.25 |   1054.84 |

The improvement is more limited on kano because a longer PCIe
initialization delays EOP in the Late EOP configuration which make it
faster to complete.

CSME team confirms that:
1. End-Of-Post is a blocking command in the sense that BIOS is
   requested to wait for the command completion before loading the OS or
   second stage bootloader.
2. The BIOS is not required to actively wait for completion of the
   command and can perform other operations in the meantime as long as
   they do not involve HECI commands.

On Raptor Lake, coreboot does not send any HECI command after
End-Of-Post.  FSP-s code review did not reveal any HECI command being
sent as part of the `AFTER_PCI_ENUM', `READY_TO_BOOT' or
`END_OF_FIRMWARE' notifications.

If any HECI send and receive command has been sent the extra code
added in `cse_receive_eop()' should catch it.

According to commit 387ec919d9 ("soc/intel/alderlake: Select
SOC_INTEL_CSE_SEND_EOP_LATE"), FSP-silicon can sometimes (on the first
boot after flashing of a Marasov board for instance) request coreboot
to perform a global request out of AFTER_PCI_ENUM notification. Global
request relies on a HECI command. Even though, we tested that it does
not create any issue, `SOC_INTEL_CSE_SEND_EOP_ASYNC' flag should not
be associated to the `SOC_INTEL_CSE_SEND_EOP_EARLY' flag to prevent
potential a global reset command to "conflict" with the EOP command.

This patch also introduces a new code logic to detect if CSE is in the
right state to handle the EOP command. Otherwise, it uses the
prescribed method to make the CSE function disable. The typical
scenario is the ChromeOS recovery boot where CSE stays in RO partition
and therefore EOP command should be avoided.

    [DEBUG]  BS: BS_PAYLOAD_LOAD exit times (exec / console): 0 / 14 ms
    [INFO ]  HECI: coreboot in recovery mode; found CSE in expected
             SOFT TEMP DISABLE state, skipping EOP

TEST=Tests on brya0 with and `SOC_INTEL_CSE_SEND_EOP_ASYNC' show
     End-Of-Post sent soon after FSP-s and EOP message receive at

     `GET_BOOT_STATE' HECI command with or without `heci_reset'. The
     implementation always successfully completed the EOP before
     moving to the payload. As expected, the boot time benefit of the
     asynchronous solution was under some injection scenario
     undermined by this unexpected HECI command.

Subrata Banik fa85b0f37c soc/intel/meteorlake: Allow to drop redundant CPU feature programming
This patch introduces a new config named
`DROP_CPU_FEATURE_PROGRAM_IN_FSP` to avoid FSP running basic CPU
feature programming on BSP and on APs using the "CpuFeaturesPei.efi"
module.

Most of this feature programming is getting performed today in scope
of coreboot doing MP Init. Running this redundant programming in
scope of FSP (when `USE_FSP_FEATURE_PROGRAM_ON_APS` config is enabled)
results in CPU exception (for example: attempting to reprogram CPU
feature lock MSR is causing CPU exception).

SoC users should select this config after dropping "CpuFeaturesPei.ffs"
module from FSP-S Firmware Volume (FV). Upon selection, coreboot runs
those additional feature programming on BSP and APs.

This feature is by default enabled, in case of "coreboot running MP
init" aka `MP_SERVICES_PPI_V2_NOOP` config is selected.

At present, this option does not do anything unless any platform
eventually decides to drop FSP feature programming module and choose
coreboot CPU feature programming over it.

John Su 294a2fd57a mb/google/skyrim: override Markarth PCIe config
Because Markarth PCIe port 1 use for eMMc not SD. So we need override
PCIe config for Markarth. And also the Markarth have NVMe and eMMC
SKU. Follow Winterhold to look at the NVMe CLKREQ signal before
initializing the ports allowing us to identify which device is populated
and only initialize that device.

Cliff Huang 69564f3de5 soc/intel/common/block/pcie/rtd3: Add root port mutex support
When 'use_rp_mutex' (default = 0) is set in the device tree, a root
port mutex will be added. This mutex is used in _ON and _OFF method,
where the GPIO reset and/or enable GPIO value is changed. The
companion driver, such as WWAN driver, needs to acquire this root
port mutex when accessing the same GPIO pins. Using this common mutex
prevents those invoked methods from being called from different thread
while one is not completed.

An example is that WWAN driver calling _RST method to reset the device
and does remove/rescan for the device while the pm runtime work might
call RTD3 _OFF.

For those root port without additional driver, this mutex is not needed.

BRANCH=firmware-brya-14505.B
TEST=boot to OS and check the generated SSDT table for the root port.
The RPMX mutex should be generated and _ON and _OFF should use this
mutex.
