Package C-state auto demotion feature allows hardware to determine lower
C-state as per platform policy. Since platform sets performance policy
to balanced from hardware, auto demotion can be disabled without
performance impact.
Also, disabling this feature results soc to enter below PC8 state and
additional power savings ~30mW in Local-Video-Playback scenario.
BUG=b:303546334
TEST=Local build successfully & Boot to OS successfully
- Also check platform enter PC8 state in local video playback

When advertising C-state using the ACPI _CST object, make sure
to only advertise those that are supported by the CPU.
Downgrade if it's not and make sure to not advertise duplicate
states.
Add debug prints for the finally selected mapping of ACPI
C-state vs Intel CPU C-state.
Test: Tested on Lenovo X220.
All C-states are still advertised as all are supported.

It was changed from a fixed size-1 array to a flexible array

This patch implements an API to report the presence of an external
display on Intel silicon. The API uses information from the transcoder
and framebuffer to determine if an external display is connected.
For example, if the transcoder is attached to any DDI ports other than
DDI-A (eDP), and the framebuffer is initialized, then it is likely
that an external display is present.
This information can be used by payloads to determine whether or not
to power on the display, even if eDP is not initialized.

This commit updates the port select bit definitions for the
TRANS_DDI_FUNC_CTL registers in the Intel GMA driver to accommodate
the changes introduced since TGL SoC.
Specifically, the following changes were made:
- Updated the DDI select bit definitions from 3-bits (bit 28-30) to
4-bits (bit 27-30).
- Introduces `INTEL_GMA_VERSION_2` config to accommodate the port and
pipe related differences between previous generation GMA register
(TRANS_DDI_FUNC_CTL) to the current generation GMA register.
This commit backports the change from the following upstream patch:

The SPL_TABLE_FILE and SPL_RW_AB_TABLE_FILE Kconfig options provide a
way to override the default SPL file configured in the SoC's fw.cfg file
by passing the '--spl-table' parameter to amdfwtool which will then use
the override instead of the SPL file from the fw.cfg file. When
SPL*_TABLE_FILE is an empty string, the corresponding add_opt_prefix
call in the makefile will result in no '--spl-table' parameter being
passed to amdfwtool, so it'll use the default SPL file from fw.cfg. In
order to not pass an SPL override by default, remove the default from
the SPL_TABLE_FILE in the SoC's Kconfig. The SoC default pointed to the
same SPL file as in fw.cfg file anyway. Now only when a mainboard sets
this option to point to a file, that file will be used as an override.
This override is used to include a special SPL file needed for the
verstage on PSP case on the Chromebooks. Since SPL_TABLE_FILE is an
empty string by default, neither the SPL_TABLE_FILE Kconfig option nor
it being evaluated in the Makefile need to be guarded by HAVE_SPL_FILE,
so remove the dependency in the Kconfig and the ifeq in the Makefile.
Before this patch, the HAVE_SPL_FILE option controlled two things that
shouldn't be controlled by the same Kconfig option: Only when
HAVE_SPL_FILE was set to y, the SPL_TABLE_FILE override was taken into
account, and it also controls if spl_fuse.c got added to the build which
when added will send the SPL fusing command to the PSP. So the case of
needing an SPL file override, but not updating the SPL fuses wasn't
supported before.
The SPL file in the amdfw part will be used by the PSP bootloader for
the anti-rollback feature which makes sure that the SPL file version
isn't lower than what is in the SPL fuses. For this the SPL file needs
to be present in the PSP directory table. The SPL version check happens
way before we're running code on the x86 cores. The SPL fusing PSP
command that can be sent by coreboot will tell the PSP to update the SPL
fuses so that the fused minimal SPL version will be updated to the
current SPL version.
Since the former HAVE_SPL_FILE option now only controls if the SPL
fusing command will be sent to the PSP mailbox, rename it to
PERFORM_SPL_FUSING to clarify what this will do and update the help text
correctly describe what this does.

During CSE FW downgrade we erase CSE data. This would result in
Platform Service Record(PSR) data also to be erased.
To avoid losing PSR data we need to make a backup before data clear.
This patch sends PSR_HECI_FW_DOWNGRADE_BACKUP HECI command to CSE,
informing the CSE to backup PSR data before a data clear operation
during downgrade.
CMOS memory is used to track the backup status. PENDING is the default
state, it is updated to DONE once PSR_HECI_FW_DOWNGRADE_BACKUP HECI
command is sent.
PSR data can be backed up only post DRAM is initialized. The idea is to
perform cse_fw_sync actions in ramstage when PSR is enabled on a
platform. As part of the cse_fw_sync actions, when a firmware downgrade
is requested the command to back-up data is sent. Once the backup has
been done, trigger the firmware downgrade.

PSR data is created and stored in CSE data partition. In platforms that
employ CSE Lite SKU firmware, a firmware downgrade involves clearing of
CSE data partition which results in PSR data being lost. The PSR data
needs to be preserved across the firmware downgrade flow. CSE Lite SKU
firmware supports command to backup PSR data. Since firmware downgrade
and PSR data backup flows involve global resets, there is a need to
track the PSR data backup status across resets. So adding a CMOS

This patch implements API to access PSR backup status stored in CMOS.

needs to be preserved across the firmware downgrade flow. CSE Lite SKU
firmware supports command to backup PSR data, and this command can be

an API to get the cse_bp_info in early romstage. The response data is
then migrated to cbmem once memory is initialized. The same data in
cbmem can be utilized in ramstage to perform other cse_fw_sync actions.
This patch also adds check to validate cse_bp_info in cbmem and avoids
sending the command again if the data is valid.

Instead of having the get_usable_physical_address_bits function that
only got used in the data fabric domain resource reporting code, drop
this function, select RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT in the
common AMD non-CAR CPU and rename get_sme_reserved_address_bits to
get_reserved_phys_addr_bits so that the common cpu_phys_address_size
function will return the correct number of usable physical address bits
which now can be used everywhere. The common AMD CAR CPU support is only
selected by Stoneyridge which doesn't support secure memory encryption,
so RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT isn't selected by the
SOC_AMD_COMMON_BLOCK_CAR Kconfig option.
Before only the MMIO region reporting took the reserved physical address
bits into account, but now also the MTRR calculation will take those
reserved bits into account. See the AMD64 Programmers Manual volume 2
(document number 24593) for details. Chapter 7.10.5 from revision 3.41
of this document was used as a reference. The MTRR handling code in
older Linux kernels complains when the upper reserved bits in the MTRR
mask weren't set, but sets them after complaining and then continues to
boot. This issue is no longer present in version 6.5 of the Linux
kernel.
The calculation of the TSEG mask however still needs to take all
physical bits into account, including the ones reserved for the memory
encryption. When not setting the reserved bits in the TSEG mask, the
Mandolin board with a Picasso APU won't boot to the OS any more due to
not returning from SeaBIOS calling into the VBIOS. Haven't root-caused
what exactly causes this breakage, but I think previously when something
else was wrong with the SMM initialization, also something went wrong
when calling into the VBIOS.
TEST=Ubuntu 2023.10 nightly build boots on Mandolin via SeaBIOS and EDK2
and Windows 10 boots on it via EDK2.
TEST=On Ubuntu 2022.04 LTS, the kernel complained with the following
warning, but it still continues the boot process as described above:

Currently, all the masters controlled by DAPC are in domain 0. With
this setting, there is a potential security problem. For example, if a
certain master is somehow hacked, it may attempt to access registers
that it is not supposed to, with successful results. This is due to the
fact that, in the current setting, all masters are in domain 0 and can
access almost all registers. To prevent this problem, we assign masters
to different domains and restrict access to registers based on each
domain.
This patch sets domains for masters:
SSPM - domain 3
CPUEB - domain 14
PCIE0 - domain 2
SPM - domain 9

Since also some AMD CPUs have reserved physical address bits that can't
be used as normal address bits, introduce the
RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT Kconfig option which gets

if the specific SoC/CPU code implements get_reserved_phys_addr_bits or
if the default of this returning 0 is used instead.

ASPM on the WLAN PCIe bus introduces large latency spikes, which can be
measured with cyclictest:
$ cyclictest --policy=rr --priority=12 --interval=10000 --threads=1 --loops=6000
Disabling ASPM for WLAN reduces the latency spikes from 2,500-3,000 usec
down to 35-65 usec. These latency spikes can impact the user when
real-time processes like Audio (cras) are starved of CPU time, leading
to buffer underruns resulting in crackling/distorted audio.
ASPM is already disabled for Nipperkin devices (CB:63537), so this CL
disables it for both in the shared declaration of
guybrush_czn_dxio_descriptors.
Power impact for Dewatt:

PSR data is created and stored in CSE data partition. In platforms that
employ CSE Lite SKU firmware, a firmware downgrade involves clearing of
CSE data partition which results in PSR data being lost. The PSR data
needs to be preserved across the firmware downgrade flow. CSE Lite SKU
firmware supports command to backup PSR data, and this command can be
sent only in post-RAM stages. So the cse_fw_sync actions needs to be
moved to ramstage.
This patch ensures SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE is selected when
PSR is enabled.

GPEs can be enabled.
GPE is used on the Librem 11 for the keyboard dock connector, its sense
signal on GPP_D4 raises a GPE which is used to indicate tablet/laptop
mode to the OS.
The register offsets are documented in the datasheet volume 2 (Intel
document 634545), all groups' GPE_STS/GPE_EN start at the same offsets.
