This patch sends the CSE EOP command asynchronous implementation early
as part of `soc_init_pre_device`.
Without this patch the duration between asynchronous CSE EOP send and
receive commands is not ample whichcauses idle delay while waiting
for EOP response.
The goal of the CSE async implementation is to avoid idle delay while
capturing the response from CSE EOP cmd.
This patch helps to create ample duration between CSE EOP command
being sent and response being captured.

PCIe bridges need to provide the LTR (latency tolerance reporting)
maximum snoop/non-snoop values so that they are inherited by downstream
PCIe devices which support and enable LTR. Without this, downstream
devices cannot have LTR enabled, which is a requirement for supporting
PCIe L1 substates. Enabling L1ss without LTR has unpredictable behavior,
including some devices refusing to enter L1 low power modes at all.

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

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.

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.

End-Of-Post sent soon after FSP-s and EOP message receive at

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.

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.

In Intel designs, internal processor errors, such as a processor
instruction retirement watchdog timeout (also known as a 3-strike

This patch prevents the Three Strike Counter from incrementing (as per
Intel EDS doc: 630094), which would help to disable Machine Check Catastrophic error. It will provide more opportunity to collect more useful CPU traces for debugging.

In the current design the relocatable parameters are used to know the
offset of the 32bit startpoint. This requires back and forward
interaction between the stub, the loader and the mp init code. This
makes the code hard to read.
This is static information known at buildtime, so a better way to deal
with this is to generate a header that contains this offset.
