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.
BUG=b:288978352
TEST=No reboot issue on rex with TME fused off

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.

Crypto Engine in PSP prefers the buffer from Static RAM (SRAM). Hence if
a buffer comes from within SRAM address range, then it is passed
directly to Crypto Engine. Otherwise a bounce bufer from the stack is
used. But on SoCs like Picasso where PSP Verstage stack is mapped to a
virtual address space this check fails causing a bounce buffer to be
used and hence a stack overflow. Fix this issue by assuming that the
buffer comes from the SRAM always in such SoCs and pass the buffer
directly to crypto engine.

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.

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.

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 USB-C display alone: has_external_display value is 1

Intel GFX IP TRANS_DDI_FUNC_CTL register bit definitions have changed
since Tiger Lake.
This register is used to map ports and pipes to display controllers,
so reflecting the correct status is important for detecting physical
display end point devices.
This patch ensures that ADL, MTL, and TGL SoCs choose GMA version 2 to
properly reflect the updated port and pipe register definitions.

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.
