The PcieRpEnable option is redundant to our on/off setting in the
devicetrees. Let's use the common coreboot infracture instead.
Thanks to Nicholas for doing all the mainboard legwork!

There is a mismatch in how PCI memory resources are allocated on Apollo
Lake with the current configuration. While the ACPI code expects
resources to be below PCR_BASE_ADDRESS (i.e. PMAX), the coreboot C code
allocates them above, leading to the following error messages on Linux:
pci_bus 0000:00: root bus resource [mem 0x000a0000-0x000bffff window]
pci_bus 0000:00: root bus resource [mem 0x80000000-0xd0000000 window]
pci_bus 0000:00: root bus resource [mem 0x280000000-0x7fffffffff window]
pci 0000:00:13.1: can't claim BAR 14 [mem 0xdeb00000-0xdebfffff]: no compatible bridge window

pci 0000:00:13.1: BAR 15: assigned [mem 0x281300000-0x2813fffff 64bit pref]
Tested on up/squared with Linux kernel version 6.1.0.
Fix this by setting the DOMAIN_RESOURCE_32BIT_LIMIT to PCR_BASE_ADDRESS,
and by moving the UART base address into the expected range.
Thanks to Nico Huber for the help in writing this patch.

Add initial support for multiple PCI segment groups. Instead of
modifying secondary in the bus struct introduce a new segment_group
struct element and keep existing common code.
Since all platforms currently only use 1 segment this is not a
functional change. On platforms that support more than 1 segment the
segment has to be set when creating the PCI domain.

The xeon_sp code worked around the coreboot allocator rather than using
it. Now the allocator is able to deal with the multiple IIOs so this is
not necessary anymore.
Instead do the following:
- Parse the FSP HOB information about IIO into coreboot PCI domains
- Use existing scan_bus and read_resource
- Handle IOAT stacks with multiple domains in soc-specific code

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.

Meteor Lake Firmware Support Package (FSP-M) for ChromeOS includes an
pre-memory graphics driver which can be leveraged to display a text
message thanks to the following FSP-M UPD (Updateable Product Data):
- VgaInitControl (bitfield):
Bit 0: Turn on graphics, setup VGA text mode and display
`VgaMessage' text centered on the screen.
Bit 1: Clear text and tear down VGA text mode and graphics before
returning from FSP-M.
- VbtPtr (address): Pointer to the VBT (Video BIOS Tables) binary.
- VbtSize (unsigned int): Size of the VBT binary.
- LidStatus (boolean): Due to limited resources at early boot stages,
the text message is displayed on a single monitor. The lid status
helps decide which display is the most appropriate.
0: Lid is closed: show the text message on the external display if
available, do not display anything otherwise.
1: Lid is open: show the message on the internal display if
available, use an external display if available otherwise.
- VgaMessage (string): Text message to display.
If the `SOC_INTEL_METEORLAKE_SIGN_OF_LIFE' flag is set, coreboot
configures the UPDs above to display a text message during memory
training and CSME update. The text message can be configured via the
locale text mechanism using the `memory_training_desc' name.
The `SOC_INTEL_METEORLAKE_SIGN_OF_LIFE' selects the LZ4 compression
algorithm for VBT because LZMA decompression is not available in
romstage by default and adding LZMA support increases the romstage
binary size more than the VBT binary is reduced.

This patch ensures that the LidStatus UPD is passed a dynamic value,
rather than always passing 1 (CONFIG_RUN_FSP_GOP enabled) for FSP 2.0
devices.
Problem statement:
* FSP-S GFX PEIM initializes the on-board display (eDP) even when the
LID is physically closed, because LidStatus is always set to 1.
* FSP-S skips external display initialization even when the LID is
closed.
Solution:
* FSP-S GFX PEIM module understands the presence of an external display
if LidStatus is not set, and tries to probe the other display
endpoint.
* Statically passing LidStatus as always enabled (aka 1) does not
illustrate the exact device scenarios, so this patch updates
LidStatus dynamically by reading the EC memory map offset.

The combination of SOC_INTEL_RAPTORLAKE_PCH_S and FSP_TYPE_IOT is
currently broken. By default, e.g. for MSI PRO Z790-P, the
FSP_HEADER_PATH does not match the default FSP_FD_PATH. For headers
the client FSP is selected, while for the FD file, IoT FSP binary
is chosen. The order of default for both headers and FD file must be
the same to match the headers and binaries.

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.
TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.

This reverts commit 44a48ce7a46c36df69f7b2cf3552bf10fa5f61b6.
Reason for revert: It breaks wakeup from suspend on a bunch of boards.
While this approach of eyeballing "correct" values by chipset _should_
be fixed, it should also be accompanied by compile time verification
that the memory map works out.
Since nobody seems to care enough, let's just revert this, instead of
keeping the tree broken for a bunch of configurations.

- the 'dptf_enable' register, which sets the ACPI device status via GNVS

This patch fixes the redundent GFX modeset issue when a dual display
is attached (e.g. an eDP display and an HDMI display).
The issue was caused by the MBUS joining logic not considering the
display type. This patch introduces three types of display: internal,
external, and dual-display. The MBUS joining logic is then updated
to consider the display type and ensure that the correct pipes are
joined to the MBUS:
For internal-only displays, only PIPE-A is joined to the MBUS.
For external displays, no pipes are joined to the MBUS.
For dual-displays, all available pipes are joined to the MBUS.

devices
When walking the devicetree to generate the list of devices and minimum
sleep states, skip any devices which have the disable or hidden flags
set. This prevents adding entries for devices which are not present,
which are hidden (and likely to not have a min sleep state entry), or
generating duplicate entries in the case of PCIe remapping.
Any of these conditions are considered invalid by Windows and will
result in a BSOD with an INTERNAL_POWER_ERROR.

Meteor Lake TME bits [42-45] are reserved regardless of if the part
supports TME or not.
On a device with TME fused off, we noticed some reboot hangs which
have been narrowed down to internal IP routing issues when the IA
accesses the Input Output Manager (IOM) which is mapped at
0x3fff0aa0000 (0x3ff upper 32 bits).
It turns out since TME is fused off, coreboot uses the full physical
address size reported by CPUID MAXPHYADDR (46 bits). Therefore, it
allocates thunderbolt memory range on 46 bits (0x3fff upper 32 bits).
Since 4 of these bits are actually reserved, it seems that this
address range is "stripped down" to 42 bits (=> 0x3ff upper 32 bits)
resulting in potential conflict with other devices such as IOM.

Having a CBFS cache scratchpad offers a generic way to decompress CBFS
files through the cbfs_map() function without having to reserve a
per-file specific memory region.
This commit introduces the x86 `PRERAM_CBFS_CACHE_SIZE' Kconfig to set
the pre-memory stages CBFS cache size. A cache size of zero disables
the CBFS cache feature. The default value is 16 KB which seems a
reasonable minimal value enough to satisfy basic needs such as the
decompression of a small configuration file. This setting can be
adjusted depending on the platform needs and capabilities.
We have set this size to zero for all the platforms without enough
space in Cache-As-RAM to accommodate the default size.

Since hex Kconfig are always defined there is no need to test it being
defined but also no need to handle zero or non-zero values.
In addition:
1. This config was defined in Meteor Lake specific Kconfig file while
it should actually be define closer to where it is being used (here
soc/intel/common/block/acpi/Kconfig) and only set by the SoC Kconfig.
2. Once moved and under control of `SOC_INTEL_COMMON_BLOCK_ACPI_LPIT'

its use.
3. Make Meteor Lake Kconfig sets the config but does not define it

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.

Get PSR bit state using MKHI_FWCAPS_GET_FW_FEATURE_STATE HECI command
Use this bit info to check if SKU supports PSR and consequently issue
PSR_HECI_FW_DOWNGRADE_BACKUP command for PSR data backup during
downgrade.
BUG=b:273207144
TEST=build CB image and boot on google/rex board. Check for
"PSR is supported in this SKU" message in coreboot logs to confirm
that PSR bit is set in SKU

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.
BRANCH=None

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
variable for the same.
This patch implements API to access PSR backup status stored in CMOS.
The get API allows to retrieve the PSR backup status from CMOS memory.
The update API allows to update the PSR backup status in CMOS.

CSE firmware downgrade and PSR data backup flows involve global resets,
there is a need to track the PSR data backup status across resets. In
the subsequent patches, a CMOS structure to store PSR back-up status
will be added.
The current SOC_INTEL_CSE_FW_PARTITION_CMOS_OFFSET of 68 can only store
cse_specific_info, as ramtop is at offset 100 and PSR back-up status
structure will not be able to fit within the range.
This patch overrides the SOC_INTEL_CSE_FW_PARTITION_CMOS_OFFSET to 161
to accommodate all CSE related info in adjacent CMOS memory.

Intel Platform Service Record(PSR) will be enabled on Meteor Lake
platforms. cse_fw_sync actions happen in ramstage when PSR is enabled.
To avoid the boot time penalty of sending the cse_get_bp_info in
ramstage, call cse_fill_bp_info to get cse_bp_info response early in
romstage and store in cbmem. This data can be later used in ramstage.

firmware supports command to backup PSR data, and this command can be

Sending cse_get_bp_info command in ramstage takes additional boot time
of ~45-55ms on rex. To avoid the boot time penalty, this patch provides
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.

TEST=Verify the command works in early romstage, data is migrated to
cbmem and valid data is available in ramstage on rex.

Jasper Lake was missing these bases, so attempting to enable an SCI
would poke unrelated registers starting from offset 0. Set them so
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.
