This patch adds `car_lib.c` to the IA common code to consolidate
SoC-agnostic CAR APIs. Initially, it includes `car_report_cache_info()`
to provide a unified way to read cache information, reducing the need
for SoC-specific implementations.

The CMOS entry for CSE partition firmware was incorrectly labeled as
`ramtop` and `partition firmware` in the error messages.
This patch corrects the messages to accurately refer to `CSE partition
firmware`.
Additionally, the alignment and size check comments are updated to
reflect this change.

This patch ensures CSE boot partition (RO/RW) version information only
log when the status is "success". If the status is not successful,
log an error message indicating the failure and status code.
This change avoids logging potentially incorrect version information
when the boot partition is not valid.

This patch refactors the handling of CSE CBMEM IDs to enable platforms
to choose whether to perform CSE sync operations within coreboot or
defer it to the payload. This separation improves code organization,
ensuring `cse_lite.c` focuses on coreboot-specific CSE Lite tasks.
Now, platforms can select:
* `SOC_INTEL_CSE_LITE_SKU` for CSE sync within coreboot
* `SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD` for deferred payload sync
This change ensures mutually exclusive options, avoiding unnecessary
SPI flash size increases.

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.

This change modifies the get_me_fw_version() function to be statically
scoped within src/soc/intel/common/block/cse/cse.c, as it is only used
by the print_me_fw_version() function in the same file.
The function declaration is also removed from intelblocks/cse.h.
The order of the function definitions in cse.c was also changed to be
more logical, with the now static helper function get_me_fw_version()
defined first, before it is used.

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.

b. Track state of PSR data during CSE downgrade operation.
2. CBMEM_ID_CSE_BP_INFO to avoid reading CSE boot partition

This also fixes Hermes booting as the PCI ops were incorrectly hooked up

As described in Intel document 336464 (8th gen S series datasheet volume
1), the CPU's 4 eDP lanes can be bifurcated, so that DDI-A (eDP) ends up
with 2 lanes, and DDI-E (DP, typically used for VGA) has the remaining 2
lanes. This lets mainboards provide a VGA output without sacrificing one
of the main 4-lane DDIs. Newer platforms seem to be lacking this.
However, the way this is structured in coreboot does not allow boards to
choose whether bifurcation should be enabled. Most boards in the tree do
not use DDI-E (it doesn't exist on mobile platforms), but there are some
boards (e.g. hp/280_g2) that use DDI-E and a DP-to-VGA converter chip to
provide a VGA output.
Replace `SOC_INTEL_CONFIGURE_DDI_A_4_LANES` with two new Kconfig options
to allow boards to decide. Use `SOC_INTEL_GFX_HAVE_DDI_A_BIFURCATION` to

otherwise, maintaining the original code's behaviour). If bifurcation is

Fast SPI code assumes only one SPI flash is present. The SPI flash
driver for older southbridges is able to detect multichip. See the
spi_is_multichip() in src/southbridge/intel/common/spi.c.
Some boards (e.g. Lenovo ThinkCentre M920 Tiny) still come with two
chips populated instead of one. With this change, both chips are probed,
and the correct total size is calculated. Otherwise, only the first one
was probed, which resulted in an error such as:
SF size 0x1000000 does not correspond to CONFIG_ROM_SIZE 0x1800000!!

When switching back and forth between 32 to 64 bit mode, for example to
call a 32-bits FSP or to call the payload, new page tables in the
respective stage will be linked.
The advantages of this approach are:
- No need to determine a good place for page tables in CBFS that does
not overlap.
- Works with non memory mapped flash (however all coreboot targets
currently do support this)
- If later stages can use their own page tables which fits better with
the vboot RO/RW flow
A disadvantage is that it increases the stage size. This could be
improved upon by using 1G pages and generating the pages at runtime.
Note: qemu cannot have the page tables in the RO boot medium and needs
to relocate them at runtime. This is why keeping the existing code with
page tables in CBFS is done for now.
TEST: Booted to payload on google/vilbox and qemu/q35

Implement watchdog for intel based platform by filling ACPI Watchdog
Action Table (WDAT) table.
The WDAT ACPI table encompasses essential watchdog functions, including:
- Setting and retrieving countdown/timeout values
- Starting and stopping the watchdog
- Pinging the watchdog
- Retrieving the cause of the last reboot, whether it was triggered by
the watchdog or another reason
The general purpose register TCO_MESSAGE1 stores the reason for the most
recent reboot rather than the original register TCO2_STS. This is
because the firmware must clear TCO2_STS, and it can't be reused for
storing this information for the operating system.
The watchdog is designed for use by the OS through certain defined
actions in the WDAT table. It relies on the ACPI Power Management Timer,
which may result in an increase in power consumption.
BUG=b:314260167
TEST=Enable CONFIG_ACPI_WDAT_WDT and CONFIG_USE_PM_ACPI_TIMER in the
config. Enable CONFIG_WDAT_WDT in the kernel config. Build and deploy
both firmware and kernel to the device. Trigger the watchdog by
performing the command: “cat > /dev/watchdog”. Wait approximately 30
seconds for the watchdog to reset the device.

This patch automates the process of determining the CSE RW version used
for the CBFS entry, eliminating the need for manual configuration in
CONFIG_SOC_INTEL_CSE_RW_VERSION.
How to get CSE RW Version:
1. Open CSE RW file as per CONFIG_SOC_INTEL_CSE_RW_FILE
2. Read offset 16 (0x10) to know the CSE version
3. Format:
- CSE_VERSION_MAJOR : offset 16-17
- CSE_VERSION_MINOR : offset 18-19
- CSE_VERSION_HOTFIX: offset 20-21
- CSE_VERSION_HOTFIX: offset 22-23
Benefits:
- Removes error-prone manual version updates.
- Prevents boot loops due to mismatched CSE RW versions (actual vs config)
- Eliminates the need for SKU-specific CSE version limitations.
BUG=b:327842062
TEST=CSE RW update successful on Screebo with this patch.

This patch moves the IP checksum algorithm into commonlib to prepare for
it being shared with libpayload. The current implementation is ancient
and pretty hard to read (and does some unnecessary questionable things
like the type-punning stuff which leads to suboptimal code generation),
so this reimplements it from scratch (that also helps with the
licensing).
This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
series for architecture-specific optimization.

Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:
CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,
This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.
It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

Multiple links are unused throughout the tree and make the code more
confusing as an iteration over all busses is needed to get downstream
devices. This also not done consistently e.g. the allocator does not
care about multiple links on busses. A better way of dealing multiple
links below a device is to feature dummy devices with each their
respective bus.
This drops the sconfig capability to declare the same device multiple

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.

With earlier flow, a chunk of CBMEM region was allocated for each SRAM
e.g., PUNIT SRAM, SOC PMC SRAM and IOE PMC SRAM. Then entire SRAM
content was copied to dedicated CBMEM region. Later in acpi_bert.c, the
BERT table was getting created for each chunk of CBMEM. This flow was
not considering creating separate entries for each region of crashlog
records. It resulted in only the first entry getting decoded from each
SRAM.
New flow aims to fix this issue. With new flow, a simple singly linked
list is created to store each region of crashlog records from all
SRAMs. The crashlog data is not copied to CBMEM. The nodes are
allocated dynamically and then copied to ACPI BERT table and then
freed. This flow also makes the overall crashlog code much simpler.

Having a separate romstage is only desirable:
- with advanced setups like vboot or normal/fallback
- boot medium is slow at startup (some ARM SOCs)
- bootblock is limited in size (Intel APL 32K)
When this is not the case there is no need for the extra complexity
that romstage brings. Including the romstage sources inside the
bootblock substantially reduces the total code footprint. Often the
resulting code is 10-20k smaller.
This is controlled via a Kconfig option.

This patch implements `.final` hooks for the IGD device to perform the
required operations before handing the control to the payload or OS.
The MBUS (Memory Bus) is a high-speed interface that connects the
graphics controller to the system memory. It provides a dedicated data
path for graphics data, which helps to improve graphics performance.
The MBUS is a key technology that helps to make the Intel i915 driver
powerful and versatile graphics drivers available. It provides the
high-speed data transfer capabilities that are essential for smooth
and responsive graphics performance.
Enable this config to ensure that the Intel GFX controller joins the
MBUS before the i915 driver is loaded. This is necessary to prevent
the i915 driver from re-initializing the display if the firmware has
already initialized it. Without this config, the i915 driver will
initialize the display to bring up the login screen although the
firmware has initialized the display using the GFX MMIO registers and
framebuffer.
Kernel graphics driver can avoid redundant display init by firmware,
which can optimize boot time by ~15ms-30ms.
Ensures hashing mode is 1x4 to enable a single pipe between Pipe A or B.
Typically, internal display is on Pipe-A, so 1x4 restricts MBUS joining
to internal display alone.

This patch adds support for detecting dual displays (eDP and HDMI) on
Intel platforms. This information is useful for setting the
`lb_framebuffer.has_external_display` variable, which is used to
determine whether depthchage should avoid shutting down when an
extended display is present.
TEST= Able to build and boot google/rex, where depthchage now
successfully avoids shutting down when both eDP and HDMI displays
are attached.
w/o this patch:
with eDP and HDMI attached: .has_external_display=0
with eDP attached: .has_external_display=0
with HDMI attached: .has_external_display=1
w/ this patch:
with eDP and HDMI attached: .has_external_display = 1
with eDP attached: .has_external_display=0
with HDMI attached: .has_external_display=1

Reserve SBREG BAR if it is outside of the PCH reserved memory range.
Desktop series processors have larger SBREG BARs, which, unlike mobile
processors, do not fall into the standard PCH reserved range
(0xfc800000 - 0xfe7fffff). Create a separate reservation for such a case. There is no telling what could happen if the reservation is not
made in ACPI.

Intel platforms use Low Power Idle Table (LPIT) to enumerate platform
Low Power Idle states. There are two types of low power residencies
a) CPU PKG C10 - read via MSR (Function fixed hardware interface)
b) Platform Controller Hub (PCH) SLP_S0 - read via memory mapped IO
Ref. https://www.uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf,
section 2.2.1: value of 0 indicates that counter runs at TSC frequency.
Ref. Intel 64 and IA-32 Architectures Software Developer’s Manual (Vol 4)
MSR 0x632: PC10 residency counter is at same frequency as the TSC.
Whereas slp_s0 residency counter running in different frequency.

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.
BUG=b:299137940
TEST=Build and boot google/rex
Scenarios:
Booting with eDP alone: has_external_display value is 0
Booting with eDP + HDMI: has_external_display value is 0
Booting with HDMI alone: has_external_display value is 1
Booting with USB-C display alone: has_external_display value is 1
