When the PSP wants to access the SPI flash during runtime, but isn't the
owner of the SPI flash controller, it sends an SMI to the x86 side. The
corresponding SMI handler then checks the P2C (PSP to core) mailbox for
the command and data, processes the command, and if needed puts the
requested data into the P2C buffer.
The P2C mailbox is a memory region in TSEG aka SMM memory. Both location
and size are communicated to the PSP via the PSP SMM info mailbox
command which is sent right after mpinit is done.
This commit adds the code to access the P2C mailbox to the PSP SMI
handler code, but the handling of the actual mailbox commands the PSP
sends to the SMI handler is added in later patches to keep the patch
size manageable.
This patch is a heavily reworked version of parts of CB:65523.
Document #55758 Rev. 2.04 was used as a reference.

Clock Power Management, ASPM and L1 Substates have been
configured the same way since Skylake. The main control to
enable or disable is Kconfig, and then the level can be overridden
in devicetree.
Despite the UPDs remaining the same since Skylake, this is not the
case for Alder Lake, Raptor Lake and Meteor Lake.
Taking `starlabs/starbook` as an example, at the time of this
commit it has PCIEXP_CLK_PM, PCIEXP_ASPM and PCIEXP_L1_SUB_STATE
enabled.
On Comet Lake, this results in the correct configuration, verified
with the lspci command:
```
LnkCap: Port #0, Speed 5GT/s, Width x1, ASPM L1, Exit Latency L1 <8us
ClockPM+ Surprise- LLActRep- BwNot- ASPMOptComp+
LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+
ExtSynch- ClockPM+ AutWidDis- BWInt- AutBWInt-
```
On Raptor Lake:
```
LnkCap: Port #0, Speed 16GT/s, Width x4, ASPM L1, Exit Latency L1 <64us
ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp+
LnkCtl: ASPM Disabled; RCB 64 bytes, Disabled- CommClk+
```
Clock Power Management, ASPM and L1 Substates are also not configured
for CPU root ports.
Add helper functions to configure these correctly based on Kconfig, but
retain the capability to override the specific levels from devicetree.

To avoid having constructs like 'dev->path.domain.domain' in the SoC
code, create the 'dev_get_domain_id' helper function that returns the
domain ID of either that device if it's a domain device or the
corresponding domain device's domain ID, and use it in the code.
If this function is called with a device other than PCI or domain type,
it won't have a domain number. In order to not need to call 'die',
'dev_get_domain_id' will print an error and return 0 which is a valid
domain number. In that case, the calling code should be fixed.

Now that we have a get_psp_mmio_base function that will work on all SoCs
that use the psp_gen2 code, we can move back to accessing the PSP
registers via their MMIO mapping. This sort-of reverts
commit 198cc26e4951 ("soc/amd/common/block/psp/psp_gen2: use SMN access
to PSP").
When doing SMN accesses from the SMI handler after the OS has taken over
ownership of the platform, there's the possibility to cause trouble by
clobbering the SMN access index register from SMM. So that should be
either avoided completely or the SMI code needs to save and restore the
original contents of the SMN index register.
The PSP MMIO base will be set up by the FSP before the resource
allocation in coreboot and be treated like a fixed resource by the
allocator. The first SMI where corresponding handler calls
'get_psp_mmio_base' happens when ramstage triggers the APM_CNT_SMMINFO
SMI right after mpinit which happens after the resource allocation. So
the PSP MMIO base address is expected to be configured and so the
'get_psp_mmio_base' function will cache the base address and won't need
to do any SMN access in subsequent calls that might happen after the OS
has take over control.
This isn't currently an issue, since the only PSP mailbox command from
the SMI handler after coreboot is done and the OS has taken over will
be during the S3/S4/S5 entry, and this will be triggered by the OS as
the last step after it is done with all its preparations for suspend/
shutdown. There will however be future patches that add SMI-handlers
which can send PSP mailbox commands during OS runtime, and so we have
to make sure we don't clobber the SMN index register.
TEST=PSP mailbox commands are still sent correctly on Mandolin.

Add get_psp_mmio_base which reads the PSP MMIO base address from the
hardware registers. Since this function will not only be called in
ramstage, but also in SMM, we can't just look for the specific domain
resource consumer like it is done for the IOAPICs in the northbridge,
but have to get this base address from the registers. In order to limit
the performance impact of this, the base address gets cached in a static
variable if an enabled PSP MMIO base register is found. We expect that
this register is locked when it was configured and enabled; if we run
into the unexpected case that the PSP MMIO register is enabled, but not
locked, set the lock bit of the corresponding base address register to
be sure that it won't change until the next reset and that the hardware
value can't be different than the cached value.
This is a preparation to move back to using MMIO access to the PSP
registers and will also enable cases that require the use of the MMIO
mapping of the PSP registers.

In AMD platforms, the bit 4 of CMOS's Register A (0x0a) is DV0 bank
selection (0 for Bank 0; 1 for Bank 1) [1]. Since the MC146818 driver
accesses VBNV via Bank 0, the bit must be cleared before we can save
VBNV to CMOS in verstage.
Usually there's no problem with that, because the Register A is
configured in cmos_init() in ramstage. However, if CMOS has lost power,
then in the first boot after that, the bit may contain arbitrary data in
verstage. If that bit happens to be 1, then CMOS writes in verstage will
fail.
To fix the problem, define vbnv_platform_init_cmos() to call
cmos_init(0), which will configure the Register A and therefore allow
saving VBNV to CMOS in verstage.

When we tried to add CMOS support to PSP verstage (CB:83495), the clang
builds failed on boards with cezanne SoC (such as Guybrush), due to
over-sized verstage. On the other hand, there is no such problem for gcc
builds on the same boards.
Building PSP verstage by clang generates much larger verstage size (81K)
compared with using gcc (67K). To unblock adding features to verstage,
temporarily enable -Oz for clang builds.

Dynamic domain SSDT generation could benefit the support of SoCs with
multiple SKUs, or the case where one set of codes supports multiple
SoCs. One possible side-effect might be the extra performance cost for
generating these tables, which should not bring big impact on high

This change skips the ME firmware version logging in
print_me_fw_version() if the ME firmware SKU is detected as Lite SKU.
The reasoning is that the RO (BP1) and RW (BP2) versions are already
logged by the cse_print_boot_partition_info() function for Lite SKUs,
making the additional log redundant.
The check for the Lite SKU has been moved to print_me_fw_version(),
where the decision to print the version is made, instead of in
get_me_fw_version(), where the version information is retrieved.

In the HD Audio Specification Rev. 1.0a, every bitfield in the GCAP
register is RO (Read Only). However, it is known that in some Intel
PCHs (e.g 6-series and 7-series, documents 324645 and 326776), some
of the bitfields in the GCAP register are R/WO (Read / Write Once).
GCAP is RO on 5-series PCHs; 8-series and 9-series PCHs have a lock
bit for GCAP elsewhere.
Lock GCAP by reading GCAP and writing back the same value. This has
no effect on platforms that implement GCAP as a RO register or lock
GCAP through a different mechanism.
