This patch creates a function to read the FSP API Reset Status. This
function relies on the FSP Scheduled Reset HOB which holds the reset
type (warm/cold/shutdown) information along with any platform specific
reset need (like global reset).
Ideally FSP API should be able to return the status (both success and
error code) upon exiting the FSP API but unfortunately there are some
scenarios in ADL/RPL FSP where MultiPhaseSiInit API is unable to return
any ERROR status. Hence, this function provides an additional hook to
read the FSP reset status by reading the dedicated HOB without relying
on the FSP API exit status code.
Additionally, create FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN config option
to handle broken FSP API return status issue.
Any SoC platform that selects the `FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN`
config will call into this newly added API to get the FSP return status
from MultiPhaseSiInit.

The patch implements an API that stores the CSE firmware version in the

machine BS_PRE_DEVICE/BS_ON_EXIT
Additionally, renamed ramstage_cse_fw_sync() to ramstage_cse_misc_ops()
in order to add more CSE related operations at ramstage.
This patch also adds a configuration option,
'SOC_INTEL_STORE_CSE_FPT_PARTITION_VERSION', which enables the storage
of firmware version information in CBMEM memory. This information can be
used to identify the firmware version that is currently installed on the
system. The option depends on the `DRIVERS_INTEL_ISH` config and
platform should be flexible enough to opt out from enabling this
feature.
The cost of sending HECI command to read the CSE FPT is significant
(~200ms) hence, the idea is to read the CSE RW version on every cold
reset (to cover the CSE update scenarios) and store into CBMEM to
avoid the cost of resending the HECI command in all consecutive warm
boots.
Later boot stages can just read the CBMEM ID to retrieve the ISH
version if required.
Finally, ensure this feature is platform specific hence, getting
enabled for the platform that would like to store the ISH version into
the CBMEM and parse to perform some additional work.

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 |

|----------+----------+-----------|
| 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 |

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.

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.

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 |

|----------+----------+-----------|
| 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 |
