Add dynamic PCI domain _OSC ASL generation codes, supporting both
PCIe and CXL domains.
Dynamic SSDT generation is used to generate a list of ASL device
objects based on FSP outputs (e.g. the SoC/SKU configurations)
and _OSC is a method inside these objects (hence it would be
straightforward to be generated altogether, plus some C codes
managed boot configs could be referenced as well).
This usage is optional. It is helpful for cases where the same
code set supports multiple SKUs/SoCs (difficult to be handled by
one set of static SSDT), and the CPU performance is good enough
to run SSDT generation logics with minimal costs.

This prepares the code for enabling both CONFIG_TPM1 and CONFIG_TPM2
during compilation, in which case actual TPM family in use can be
determined at runtime.
In some places both compile-time and runtime checks are necessary.
Yet in places like probe functions runtime state checks don't make sense
as runtime state is defined by results of probing.

Even though it has an 'amd_' prefix, the amd_pci_domain_fill_ssdt
implementation doesn't contain any AMD-specific code and can also be
used by other SoCs. So factor it out, move the implementation to
src/acpi/acpigen_pci_root_resource_producer.c, and rename it to
pci_domain_fill_ssdt. When a SoC now assigns pci_domain_fill_ssdt to its
domain operation's acpi_fill_ssdt function pointer, the PCI domain
resource producer information will be added to the SSDT.

The physical address size of the System-on-Chip (SoC) can be different
from the CPU physical address size. These two different physical
address sizes should be used for settings of their respective field.
For instance, the physical address size related to the CPU should be
used for MTRR programming while the physical address size of the SoC
should be used for MMIO resource allocation.
Typically, on Meteor Lake, the CPUs physical address size is 46 if TME
is disabled and 42 if TME is enabled but Meteor Lake SoC physical
address size is always 42. As a result, MTRRs should reflect the TME
status while coreboot MMIO resource allocator should always use
42 bits.
This commit introduces `SOC_PHYSICAL_ADDRESS_WIDTH' Kconfig to set the
physical address size of the SoC for those SoCs.

Previously acpigen_pop_len always wrote a 3 byte PkgLength to the 3
bytes reserved by acpigen_write_len_f. After this patch acpigen_pop_len
encodes PkgLength in 1-3 bytes depending on the PkgLength. When less
than the 3 bytes that were previously reserved in the corresponding
acpigen_write_len_f call are needed for PkgLength, the payload data will
be moved back by the number of reserved bytes that aren't needed for the
PkgLength.
This fixes the problem that the Windows AML parser doesn't like a 3 byte
PkgLength being used for the size of the buffer containing UTF-16
strings when the length could be encoded in a single PkgLength byte. In
that case, Windows previously ignored the whole SSDT containing this
larger than necessary PkgLength encoding. It should however be noted
that the ACPI 6.4 spec doesn't specify if it's required to always use
the most compact possible encoding of the PkgLength or not. Since iasl
generates the shortest possible PkgLength encoding, it's also a good
idea to make coreboot's acpigen do the same although it's not required
by the specification.
With this patch applied, Windows still boots on Mandolin and the time it
takes to write the tables doesn't change. To measure the times, the log
level in bs_sample_time was increased to BIOS_CRIT and the console log
level was increased to BIOS_CRIT too to only get those times as output.
BS: BS_WRITE_TABLES run times (exec / console): 8 / 0 ms

Since d8f2dce "acpi.c: Swap XSDT and RSDT for adding/finding tables"
XSDT is primarily used to add new tables or to find the S3 resume vector.
However with QEMU coreboot does not generate most ACPI tables but takes
them from whatever QEMU provides. Qemu only creates an RSDT and lacks an
XSDT.
To keep the codebase simple with the assumption that XSDT is always
present, create an XSDT based on the existing RSDT and update the
address in RSDP.

In soundwire.h, SOUNDWIRE_DPN MIN & MAX are set to 1 and 14. When
creating the dpn array, the length was set to MAX - MIN or 13, numbered
0 to 12.
When accessing the array, the code was bailing out if a value greater
than MAX was trying to be accessed, so the array was able to be overrun
by two structure lengths.
Fix this problem by:
1) Not subtracting the MIN value when creating the array, which does
waste a little space. If anyone wants to refactor the code to fix that,
please feel free.
2) Breaking out of the loop when the port is equal to the MAX port
number instead of just when it's greater than the max port number.

If ACPI is above 4G it's not possible to have a valid RSDT pointer in
RSDP, therefore swap RSDT and XSDT. Both are always generated on x86.
On other architectures RSDT is often skipped, e.g. aarch64. On top of
that the OS looks at XSDT first. So unconditionally using XSDT and not
RSDT is fine.
This also deal with the ACPI pointer being above 4G. This currently
never happens with x86 platforms.

From the Linux documentation (Documentation/PCI/acpi-info.rst):
[6] PCI Firmware 3.2, sec 4.1.2:
If the operating system does not natively comprehend reserving the
MMCFG region, the MMCFG region must be reserved by firmware. The
address range reported in the MCFG table or by _CBA method (see Section
4.1.3) must be reserved by declaring a motherboard resource. For most
systems, the motherboard resource would appear at the root of the ACPI
namespace (under \_SB) in a node with a _HID of EISAID (PNP0C02), and
the resources in this case should not be claimed in the root PCI bus’s
_CRS. The resources can optionally be returned in Int15 E820 or
EFIGetMemoryMap as reserved memory but must always be reported through
ACPI as a motherboard resource.
So in order for the OS to use ECAM MMCONF over legacy PCI IO
configuration, a PNP0C02 HID device needs to reserve this region.
As no AMD platform has this defined in DSDT this fixes Linux using
legacy PCI IO configuration over MMCONF. Tianocore messes with e820
table in such a way that it prevents Linux from using PCIe ECAM. This
change fixes that problem.

This was missed recently when adding the table. Linux complains about
the missing checksum, e.g.
[ 0.186070] ACPI BIOS Warning (bug): Incorrect checksum in table [SPCR] - 0x00, should be 0x87 (20210730/tbprint-173)
Tested with QEMU/Q35, albeit with changes to the special handling for
ACPI with QEMU. The warning goes away.

Sometimes systems don't boot to the OS due to wrong ACPI tables.
Printing the tables in an ACPICA compatible format makes analysis of
ACPI tables easier.
The ACPICA format (acpidump, acpixtract) is the following:
"
FACS @ 0x0000000000000000
0000: 46 41 43 53 40 00 00 00 E8 24 00 00 00 00 00 00 FACS@....$......
0010: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
0020: 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
"
To achieve analyze ACPI tables capture the coreboot log between
"Printing ACPI in ACPICA compatible table" and "Done printing ACPI in
ACPICA compatible table". Remove the prefix "[SPEW ] " and then call
'acpixtract -a dump' to extract all the tables. Then use 'iasl -d' on
the .dat files to decompile the tables.

When an IO resource producer is generated that covers the whole IO space
from 0 to 0xffff, the length field in the word resource ACPI type would
overflow and be truncated which results in Linux not finding any usable
IO space to use for the PCI IO BARs. Instead generate a double word IO
resource producer to have all cases supported. Beware that covering all
IO ports with the IO resource producer while covering the PCI config IO
ports with a resource consumer in the same PCI root device will make
Linux a bit unhappy and it will complain due to the overlap, but still
end up doing the right thing:
acpi PNP0A08:00: host bridge window expanded to [io 0x0000-0xffff]; [io 0x0000-0xffff window] ignored
The SoC code should make sure to carve out the PCI config IO ports from
the IO resource producer.
TEST=Both Ubuntu 2022.04.1 LTS and Windows 10 are ok with the IO DWord
resource producer.

The acpigen_resource_[bus_number,io,mmio*] functions didn't make it very
clear that they are generating resource producer ranges and not resource
consumer ranges. To clarify this, change the function names to
acpigen_resource_producer_[bus_number,io,mmio*] and explicitly add the

This timeout message won't be displayed when this function is used as
delay loop (ie. without checking variable condition).

Here is an example of generated code when waiting for variable L23E to
be 0.
Local7 = 0x08
While ((Local7 > Zero))
{
If ((L23E == Zero))

}

Since it's not obvious, add comments to acpigen_resource_word,
acpigen_resource_dword and acpigen_resource_qword to clarify out what
the magic number in byte 0 means. The most significant bit of byte 0
indicates if it is a small or large resource data type. In the case of
the MSB being 0, it's a small resource data type (aka type 0), and the
other bits encode bit the type and size of the item; if the MSB is 1,
it's a large resource data type (aka type 1), and the other bits just
encode the type and there are two separate bytes to encode the size.
Beware that the large resource's data type values in the ACPI
specification don't include the MSB that's set, but only the 7 lower
bits.

In ACPI 1.0 the processor objects were inside the \_PR scope, but since
ACPI 2.0 the \_SB scope can be used for that. Outside of coreboot some
firmwares still used the \_PR scope for a while for legacy ACPI 1.0 OS
compatibility, but apart from that the \_PR scope is deprecated.
coreboot already uses the \_SB scope for the processor devices
everywhere, so move the \_SB scope out of the ACPI_CPU_STRING to the
format string inside the 3 snprintf statements that use the
ACPI_CPU_STRING.

This reverts commit 4dba71fd25c91a9e610287c61238a8fe24452e4e.
Add multiple fan support for dptf policies.
This also fixes the Google Meet resolution drop issue as per
b:246535768 comment#12. When system starts Google Meet video call,
it uses the hardware accelerated encoder as expected. But, as soon as
another system connects to the call, an immediate fallback is observed
from hardware to software encoder. Due to this, Google Meet resolution
dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC
based fanless platforms. This same issue was not seen on fan based
systems. With the fix in dptf driver where fan configures appropriate
setting for only fan participant, not for other device participants,
able to see consistent 720p resolution.
BUG=b:246535768,b:235254828
BRANCH=None
TEST=Built and tested on Alder Lake-P Redrix system for two fans
support and on Alder Lake-N fanless systems. With this code change
Google Meet resolution drop not observed.
