TOLUD stands for top of lower usable dram. Memory between cbmem_top and
TOLUD, even if stolen for another device/purpose can still be marked WB
cacheable. This will result in a cleaner MTRR setup.

On nissa, the pre-x86 time is not part of the 1s firmware boot time
target. Including the pre-x86 timestamps causes confusion since the boot
time appears to be greater than 1s, so disable the Kconfig on nissa.
We're not doing any analysis or optimisation of the pre-x86 time on
nissa anyway, this work will start from MTL onwards. Also, the Kconfig
is already disabled on the brya firmware branch, so this will result in
the same behaviour as brya.

Configure FSP S UPDs to allow coreboot to handle the lockdown.
The main change here is setting `Write Protection Support` to 0,
as the default is Enabled, which shouldn't allow writes (even though
it seems to).
The UPDs are identical on APL and GLK, but all ones configured
in this patch have been there since their initial releases.

RaptorLake introduces the support of the Voltage Regulator Fast Vmode
feature. When enabled, it makes the SoC throttle when the current
exceeds the I_TRIP threshold. This threshold should be between
Iccmax.app and Iccmax and take into account the specification of the
Voltage Regulator of the system.
This change provides a mean to:
1. Enable the feature via the `vr_config->enable_fast_vmode'. If no
I_TRIP value is supplied FSPs picks an adapted I_TRIP value for
the current SoC assuming a Voltage Regulator error accuracy of
6.5%.
2. Set the I_TRIP threshold via the `vr_config->fast_vmode_i_trip'
field.
These new fields are considered independent from the other `vr_config'
fields so that the board configuration does not have to unnecessarily
supply other VR settings to enable Fast VMode.
Information about the Fast VMode Feature can be found in the following
Intel documents:
- 627270 ADL and RPL Processor Family Core and Uncore BIOS
Specification
- 724220 RaptorLake Platform Fast V-Mode
- 686872 RaptorLake Lake U P H Platform

Add SOC_INTEL_COMMON_PCH_CLIENT which is specific to Apollo
Lake. This is used to select the options that Apollo Lake
requires, without the ones specific to a PCH as Apollo Lake
doesn't have a PCH.
This change also enables SOC_INTEL_COMMON_PCH_LOCKDOWN for
Apollo Lake.

The fast SPI driver reports the BIOS window as reserved so that the OS
is aware of this region. Now that platforms which supports an extended
BIOS window are added to this driver, add the extended range as reserved
as well if it is enabled. And since this is now handled in the SPI
driver itself, remove the extended BIOS region reporting from
common systemagent code.

There are two classes of SPI controllers on Intel chipsets:
* generic usable SPI controllers
* SPI controller hosting the BIOS flash (fast SPI controller)
While the first class can be used for generic peripheral attachment the
second class mostly controls the BIOS flash and a TPM device (if
enabled). The generic SPI driver is not fully applicable to the fast SPI
controller. In addition, the fast SPI controller reports the reserved
MMIO range used for the BIOS flash mapping so that the OS is aware of
this range.
This patch moves the fast SPI controller of all known SoCs to the
fast SPI driver in common code. In addition, the PCI device for the
fast SPI controller is removed from the function 'spi_soc_devfn_to_bus'
as this is a callback of the generic SPI driver.

FSP silicon 3347 changed the default value of the EnergyEfficientTurbo
Updateable Product Data (UPD), enabling the Energy Efficient Turbo
feature by default. This feature prevents the cores from entering
Turbo frequency under heavy load.
As a result of this FSP change, coreboot explicitly disables this
feature to stay consistent with commit `caa5f59279e Revert

Some PCI IDs were missing, and at least one (SPT's fast SPI
device in a generic SPI driver) was wrong. Hence, this patch
actually changes behavior depending on the devices actually
present in a machine.
In this patch the Skylake devicetree is written in a single-line
style. Alternative, the device operations could be put on a separate
line, e.g.
device pci 00.0 alias system_agent on
ops systemagent_ops
end
Tested on Kontron/bSL6. Notable in the log diff is that the
CSE and SATA drivers are hooked up now.

This patch fixes a hidden issue present inside FSP-S while coreboot
decides to skip performing MP initialization by overriding FSP-S UPDs
as below:
1. CpuMpPpi ------> Passing `NULL` as coreboot assume FSP don't need
to use coreboot wrapper for performing any
operation over APs.
2. SkipMpInit -----> Set `1` to let FSP know that coreboot decided
to skip FSP running CPU feature programming.
Unfortunately, the assumption of coreboot is not aligned with FSP when
it comes to the behaviour of `CpuMpPpi` UPD. FSP assumes ownership of
the APs (Application Processors) upon passing `NULL` pointer to the
`CpuMpPpi` FSP-S UPD.
FSP-S creates its own infrastructure code after seeing the CpuMpPpi
UPD is set to `NULL`. FSP requires the CpuMpPei module, file name `UefiCpuPkg/CpuMpPei/CpuMpPei.c`, function name `InitializeCpuMpWorker`
to perform those additional initialization which is not relevant for
the coreboot upon selecting the SkipMpInit UPD to 1 (a.k.a avoid
running CPU feature programming on APs).
Additionally, FSP-S binary size has increased by ~30KB (irrespective of
being compressed) with the inclusion of the CpuMpPei module, which is
eventually not meaningful for coreboot.
Hence, this patch selects `MP_SERVICES_PPI_V2_NOOP` config
unconditionally to ensure pass a valid pointer to the `CpuMpPpi` UPD
and avoid APs getting hijacked by FSP while coreboot decides to set
SkipMpInit UPD.
Ideally, FSP should have avoided all AP related operations when
coreboot requested FSP to skip MP init by overriding required UPDs.
TEST=Able to drop CpuMpPei Module from FSP and boot to Chrome OS on
Google/Redrix, Kano, Taeko devices with SkipMpInit=1.
Without this patch:
Here is the CPU AP logs coming from the EDK2 (open-source)

CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.
Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:
Updating from commit id 18cb85b5:
2load_kernel.c: Expose load kernel as vb2_api
to commit id b827ddb9:
tests: Ensure auxfw sync runs after EC sync
This brings in 15 new commits.

Enabling Bus Master isn't required by the hardware, so we shouldn't
need to enable it at all. However, some payloads do not set this bit
before attempting DMA transfers, which results in functionality
failure. For example: in this case, unable to see the developer screen
in Depthcharge.
In the prior IA SoC platform, FSP/GFX PEIM does the BM enabling for
the IGD BAR resources but starting with the MTL platform, it fails
to do so resulting into inability to see the Pre-OS display.

This patch refactors p2sb_execute_sideband_access() to be able to
handle SBI operations in both SMM and non-SMM scenarios.
Prior to FSP-S operation being done, the IOE P2SB device will be
visible on the PCI bus hence, performing the SBI operation using IOE
P2SB doesn't involve unhide/hide operation.
Post FSP-S, the IOE P2SB device is hidden.
Additionally, SBI operations can't be performed as is. The only
possible way to send SBI is inside SMM mode and to do that, coreboot
needs to unhide the P2SB device prior to sending the SBI and hide
it post sending SBI.
As a result, the p2sb_execute_sideband_access() function has been
refactored to manage these cases seamlessly without users of the
p2sb_execute_sideband_access() actually being bothered about the
calling mode.
BUG=b:239806774

This patch removes the static kconfig being used to fill in TME enable
FSP UPD. Instead use`is_tme_supported()` and `CONFIG(INTEL_TME)` to check
if the CPU has required TME support rather than hardcoding.
TEST=FSP debug log shows `TmeEnable` UPD is set appropriately for the
TME-supported CPU SKUs.
As per FSP-M debug log:
Without this CL, Alder Lake-P CPU SKU without TME support:
[SPEW ] TmeEnable = 0x1
With this CL, Alder Lake-P CPU SKU without TME support:
[SPEW ] TmeEnable = 0x0

As per the Alder Lake FAS coreboot shall detect the existence of TME
feature by running the CPUID instruction:
CPUID leaf 7/sub-leaf 0
Return Value in ECX [bit 13]=1
If TME is supported then only access to TME MSRs are allowed otherwise
accessing those MSRs would result in GP#.
TEST=Able to detect the existence of TME feature across different
Alder Lake and Meteor Lake CPU SKUs.
