In EC versions older than 1.18, if the mirror flag was enabled, the
EC would mirror once the system reached S5.
When a mirror is successful, the system will automatically power
on, as it acts like it's been in G3. This led to machines turning on
when the intention was them to be off.
In 1.18 and later, they're installed when turning on. The result was
slower boot times when mirroring, but no unwanted powering on.
Because of this, coreboot no longer needs to power off when setting
the mirror flag.

CONFIG(STATIC_OPTION_TABLE) can no longer resume from s3 (detected via
bisect).
Further inspection shows that DRAM training result of GM45 is stored
in CMOS above 128 bytes in raminit_read_write_training.c, for s3 resume
to restore, but it will be erased by sanitize_cmos(), which now clears
both bank 0 and bank 1, leaving only "untrained" result restored, so s3
resume will fail.
However, resetting CMOS seems unnecessary during s3 resume. Now,
cmos_need_reset will be negated when acpi_is_wakeup_s3() returns true.
Tested: Thinkpad X200 with CONFIG(STATIC_OPTION_TABLE) can resume from
s3 again with these changes.

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.

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.

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.

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.
