According the Intel Software Developer Manual,
CPUID.80000008H:EAX[15:8] reports the physical-address width supported
by the processor. Unfortunately, it does not necessarily reflect the
physical-address space the system can actulally use as some of those
bits can be reserved for internal hardware use.
It is critical for coreboot to know the actual physical address size.
Overestimating this size can lead to device resource overlaps due to
the hardware ignoring upper reserved bits. On rex for instance, it
creates some reboot hangs due to an overlap between thunderbolt and
Input Output Manager (IOM) address space.
As some SoCs, such as Meteor Lake, have physical address reserved bits
which cannot be probed at runtime, this commit introduces
`CPU_INTEL_COMMON_RESERVED_PHYS_ADDR_BITS' Kconfig to set the number
of physical address reserved bits at compilation time for those SoCs.
A runtime detection by hardware probing will be attempted if the value
is 0 (default).

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 `RAMSTAGE_CBFS_CACHE_SIZE' Kconfig to
set a ramstage CBFS cache size. A cache size of zero disables the
CBFS cache feature. The default size is 16 KB which seems a
reasonable minimal value large 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.
To support S3 suspend/resume use-case, the CBFS cache memory cannot be
released to the operating system. There are two options to meet this
requirement:
1. Define a static CBFS cache buffer (located in the .bss section)
2. Create a new CBMEM entry
Option #2 seems more powerful but considering that:
1. The CBFS cache is actually not a cache but just a scratch pad
designed to be isolated between stages
2. postcar is a very short stage not really needing CBFS cache
3. The static initialization of the `cbfs_cache' global
variable (cf. src/lib/cbfs.c) offers a simple and robust design
=> It is simpler to use a static buffer and limit the support to
ramstage.
Since some AMD SoCs (cf. `SOC_AMD_COMMON_BLOCK_NONCAR' Kconfig) define
a `_cbfs_cache' region, an extra `POSTRAM_CBFS_CACHE_IN_BSS' Kconfig
must be set to enable the use of a static buffer as the CBFS cache
scratchpad.

The linker can make relocation entries of a symbol which has a value
of zero point to the undefined symbol entry. It is permitted since
when the symbol value is zero as the documentation of the relocation
entry `r_info' field states:
"If the index is STN_UNDEF, the undefined symbol index, the relocation
uses 0 as the symbol value."
The ELF binary does not really have any missing symbols. It is an
optimization as the symbol points to the undefined symbol because its
value is zero.
A typical way to hit this cbfstool limitation is to define an empty
region using the REGION macro in the linker script. Here is an
example if we assume `CONFIG_MY_REGION' is set to 0:
.car.data {
[...]
REGION(my_region, CONFIG_MY_REGION_SIZE)
[...]
}
A region is defined as follow:
#define REGION_SIZE(name) ((size_t)_##name##_size)
#define DECLARE_REGION(name) \
extern u8 _##name[]; \
extern u8 _e##name[]; \
extern u8 _##name##_size[];
So the size of the region is actually the address of the
`_##name##_size' symbol. Therefore, the `_my_region_size' symbol
address is zero and the linker can make the relocation entry of this
symbol point to the undefined symbol index.
In such a situation, cbfstool hits a segmentation fault when it
attempts to relocate the symbol in `parse_elf_to_xip_stage()'
function. We resolves this issue by making cbfstool skips relocation
entries pointing to the undefined symbol similarly to the way it skips
relocation relative to absolute symbols. A symbol which value is zero
can be considered an absolute symbol and therefore should not be
relocated.
Of course, we could argue that we could just prevent the declaration
of an empty region as illustrated in the following example:
.car.data {
[...]
#if CONFIG_MY_REGION_SIZE > 0
REGION(my_region, CONFIG_MY_REGION_SIZE)
#endif
[...]
}
However, this is not a satisfying solution because:
1. It requires to add unnecessary code in the linker script as an empty
region is a valid declaration. Such a workaround requires the code
using it to mark the region symbols as weak symbols to handle the
situation where the region is not defined.
2. There could be other situations which have yet to be uncovered which
would lead the same cbfstool crash.
3. A binary with an empty region is a valid ELF file and cbfstool
should not crash when it is asked to create an eXecute-In-Place stage
out of it.

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.

Support embedding a second FSP-M/FSP-S binary for an SoC that can

Comet Lake v1 and v2 are different steppings of the same SKUs, but they
require different FSP binaries. Supporting both in a single build
requires embedding both FSPs and selecting one at runtime based on the
CPUID. This is desirable for a product that may have different CPU
steppings but is not otherwise differentiated enough for a separate
firmware build.
An SoC can select PLATFORM_USES_SECOND_FSP to indicate that two FSP-M/
FSP-S binaries are required. Implement soc_select_fsp_m_cbfs() and
soc_select_fsp_s_cbfs() to choose one based on platform-specific
criteria. For Comet Lake, the first FSP is CML v1 and the second is
CML v2, but in principle a platform could define any meaning for the
first and second FSP.
FSP-T is not affected, only one FSP-T can be embedded if FSP_CAR is
used.
Only one set of FSP headers is used, which is sufficient for Comet Lake
v1/v2; their headers are equivalent.
ADD_FSP_BINARIES, FSP_USE_REPO, and FSP_FULL_FD are supported for both
sets of FSP-S/FSP-M but cannot be configured separately, both use the
same configuration.

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.

This patch ensures that the IGD joins the MBUS when the firmware splash
screen feature is enabled (aka BMP_LOGO config is enabled).
For ChromeOS platform, it prevents the i915 driver from reinitializing
the display, which can save up to 75ms-80ms of boot time and eliminate
a brief period of blank screen between the firmware splash screen and
the OS login prompt.

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.
