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.

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 387ec919d9f7 ("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.
BUG=b:276339544
BRANCH=firmware-brya-14505.B
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
`BS_PAYLOAD_BOOT'. Verify robustness by injecting a
`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.

The default SPD size is set to 256 bytes, instead of 512 for
LPDDR4/DDR4 if not overridden by the mainboard Kconfig. This caused
the SMBus libraries to read only the lower half of the DIMM SPD on
protectli/vault_ehl. The lower half of the SPD passed to FSP causes
a bug in DIMM change detection, which relies on the CRC of the
manufacturer bytes in the upper half of the SPD (CRC of zero bytes
always gives zero so no change was assumed). Setting the DIMM SPD size
to 512 fixes it.
Setting the SPD size in SoC will also avoid such problems in the future
Elkhart Lake ports. Elkhart Lake supports only LPDDR4/DDR4 so providing
the correct default of 512 bytes is an obvious thing to do.
TEST=Boot Protectli VP2420 (vault_ehl) with different DIMMs and see
FSP is retraining the memory instead of doing the fastboot with old
DIMM data.

Commit 6a6ac1e0b929 ("arch/x86/cpu: introduce and use
device_match_mask") added the device_match_mask element to the
cpu_device_id struct and uses it to be able to mask off for example the
stepping ID when checking for CPU table entry that matches the silicon
the code is running on. Commit 3ed903fda9cb ("soc/intel/xeon_sp/spr: Add
Sapphire Rapids ramstage code") added a CPU table that was missing the
device_match_mask which results in this being 0, so the first entry of
the CPU table would match for any Intel CPU which isn't the intended
behavior. Also use CPU_TABLE_END instead of the final {0, 0, 0} array
element.
Likely all entries could be replaced by one entry that uses the
CPUID_ALL_STEPPINGS_MASK instead of the CPUID_EXACT_MATCH_MASK, but
that's out of scope for this fix.

This patch implements a module that can store the top_of_ram (TOM)
address into non-volatile space (CMOS) during the first boot and
use it across all consecutive boot.
As top_of_ram address is not known until FSP-M has exited, it
results into lacking of MTRR programming to cache the 16 MB TOM,
hence accessing that range during FSP-M and/or late romstage causing
long access times.
Purpose of this driver code is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).
TEST=Able to build and boot google/rex to ChromeOS.

The reset bit mapping was incorrectly assigned to GPIO groups. The
reset mapping for Community 0 actually reflects the GPD reset mapping.
Change the Community 0 reset mapping to the correct default map and fix
the GPD reset mapping.

Introduce at new config option CONFIG_FSP_PUBLISH_MBP_HOB to control
the creation of ME_BIOS_PAYLOAD_HOB (MBP HOB) by FSP.
This new option is hooked with `SkipMbpHob` UPD and is always disabled
for RPL & ADL-N based ChromeOS platforms.
It is not disabled for ADL-P based platforms because ADL-P FSP relies
on MBP HOB for ChipsetInit version for ChipsetInit sync. As ChipsetInit
sync doesn't occur if no MBP HOB, so it results S0ix issue. This
limitation is addressed in the later platforms so creation of MBP HOB
can be skipped for ADL-N and RPL based platforms.
This made skip_mbp_hob SOC chip config variable redundant which is also
removed as part of this change.
BUG=none

This fixes MP init on xeon_sp SoCs which was broken by 69cd729 (mb/*:
Remove lapic from devicetree).
Alderlake cpu code was linked in romstage but unused so drop it.
