Currently the SMMSTOREv2 only supports MMIO ROM below 4GiB. As the
space below 4GiB is typically limited on x86, add support for extended
MMIO ROM windows as found on recent hardware.
Allow the SMMSTOREv2 to be memory mapped above 4GiB by adding a new
field to the coreboot table called 'mmap_addr'. The users outside
of coreboot must check the size field of the coreboot struct to
determine if mmap_addr is supported. When it is it holds the
64-bit physical address to the MMIO ROM window.
The old 'mmap_addr' was renamed to 'mmap_addr_deprecated' to indicate
that it should not be used any more.

This change refactors MTRR handling by consolidating helper functions
from `earlymtrr.c` and `mtrr.c` into a new MTRR library (`mtrrlib`).
This approach improves code modularity and reusability, making these
utilities consistently available across different coreboot boot phases.
The following functions are now part of `mtrrlib`:
- `get_free_var_mtrr`: Retrieves the index of the first available
variable MTRR.
- `set_var_mtrr`: Configures the variable MTRR, specified by an `index`,
for a memory region defined by `base`, `size`, and `type`.
- `clear_var_mtrr`: Disables the variable MTRR at a given index.
- `acquire_and_configure_mtrr`: Acquires a free variable MTRR, configures
it with the given `base`, `size`, and `type`.

Currently there are 3 GDTs (Global Descriptor Tables) being used on x86:
- preRAM (gdt_init.S)
- SMM (smm_stub.S)
- RAM (c_start.S)
They have different layouts and thus different offsets for the segments
being used in assembly code. Stop using different GDT segments and
ensure that for ROM (preRAM + SMM) and RAM (ramstage) the segments
match. RAM will have additional entries, not found in pre RAM GDT,
but the segments for protected mode and 64-bit mode now match in
all stages.
This allows to use the same defines in all stages. It also drops the
need to know in which stage the code is compiled and it's no longer
necessary to switch the code segment between stages.
While at it fix the comments in the ramstage GDT and drop unused
declarations from header files, always set the accessed bit and drop
GDT_CODE_ACPI_SEG.

With DRIVERS_EFI_UPDATE_CAPSULES enabled and when at least one capsule
was found, SMMSTORE SMI handler can use commands with the highest
bit (0x80) set to access the whole flash instead of just the SMMSTORE
region. The rest of the interface is identical to regular SMMSTORE v2
except for a new call to control full flash access.
The added call saves information about the availability of capsules in
SMM memory. The call is ignored when run more than once, meaning there
should be no way of enabling full flash handling after it was disabled
and vice versa. The call should always be made by the firmware to lock
further calls, so that an OS could not gain full flash access. This is
done on entry to BS_POST_DEVICE after capsules are obtained in
BS_DEV_INIT.

RISC-V doesn't support unaligned access, so check for that before
decoding and encoding. It is not perfectly performant, but still much
better then invoking the misaligned exception handler every time there
is a misaligned access. We can't modify our whole codebase to always do
aligned access, because it is neither feasible in long term nor is fair
to add that performance penalty onto other architectures that do support
unaligned access. So this is the next best thing.
On architectures that do support unaligned access the compiler will just
optimize the RISCV_ENV part out and should result in the exact same
binary.

This patch refactors low-battery user notification logic (Kconfig,
APIs to check if low-battery rendering is required, low-battery
shutdown is required) outside FSP driver code to ensure in future
non-FSP platforms might still be able to leverage this feature/logics
to render the low-battery indicator icon during boot.
Specifically, it:
- Moves Kconfig options related to low-battery notifications from
drivers/intel/fsp to lib/
- Relocates the low-battery check and shutdown APIs drivers/intel/fsp
to bootsplash.h
* Adjusts the vendor driver to utilize the new APIs for low-battery
rendering decisions.
* Drop the unwanted header file "fsp/api.h" from bmp_logo.c
This change avoids tight coupling of low-battery functionality to FSP,
promoting code reusability across platforms.

Add a new option backend that uses values stored in CBFS files, similar
to the SeaBIOS runtime config options stored in files with the etc/
prefix. Options should be stored in CBFS with the option/ prefix. Values
can be set using `cbfstool coreboot.rom add-int -n option/<option-name>
-i <value>`. For simplicity, options should be stored in the COREBOOT
(RO) FMAP region, which is the default for cbfstool. This backend is not
available in SMM due to CBFS dependencies on vboot functions which are
not added to SMM, and thus the fallback will be returned by calls to
get_uint_option() in SMM.
Tested with QEMU Q35 by setting various options for "sata_mode" and
observing the console output for the SATA controller mode during
i82801ix_sata initialization.

This resolves a crash issue observed on Meteor Lake and introduced by
commit 70bdd2e1fa ("cpu/x86/topology:
Simplify CPU topology initialization"). This commit simplifies the
code and provides more detailed CPU topology information by
generalizing the use of the Extended Topology Enumeration Leaves
0x1f. As a result, the coreboot APIC core_id field does not provide
the fully detailed path information.
It turns out that the topology core identifier is used by the coreboot
MP service mp_get_processor_info() implementation. But the MP Service
EFI_CPU_PHYSICAL_LOCATION data structure only captures information
about the package, core, and thread. The core identifier returned to
the MP service caller must incorporate the full hierarchical path (die
group, die, module, tile, module and core).
This commit adds a new field to the cpu topology structure to
represent the core ID within the package.
For reference, here is that signature of the crash:
LAPIC 0x40 in X2APIC mode.

Introduce a mechanism so that coreboot can provide a list of options to
post-coreboot code. The options are grouped together into forms and
have a meaning name and optional help text. This can be used to let
payloads know which options should be displayed in a setup menu,
for instance. Although this system was written to be used with edk2,
it has been designed with flexibility in mind so that other payloads
can also make use of this mechanism. The system currently lacks a way
to describe where to find option values.
This information is stored in a set of data structures specifically
created for this purpose. This format is known as CFR, which means
"coreboot forms representation" or "cursed forms representation".
Although the "forms representation" is borrowed from UEFI, CFR can
be used in non-UEFI scenarios as well.
The data structures are implemented as an extension of cbtables records
to support nesting. It should not break backwards compatibility because
the CFR root record (LB_TAG_CFR_ROOT) size includes all of its children
records. The concept of record nesting is borrowed from the records for
CMOS options. It is not possible to reuse the CMOS records because they
are too closely coupled with CMOS options; using these structures would
needlessly restrict more capable backends to what can be done with CMOS
options, which is undesired.
Because CFR supports variable-length components, directly transforming
options into CFR structures is not a trivial process. Furthermore, CFR
structures need to be written in one go. Because of this, abstractions
exist to generate CFR structures from a set of "setup menu" structures
that are coreboot-specific and could be integrated with the devicetree
at some point. Note that `struct sm_object` is a tagged union. This is
used to have lists of options in an array, as building linked lists of
options at runtime is extremely impractical because options would have
to be added at the end of the linked list to maintain option order. To
avoid mistakes defining `struct sm_object` values, helper macros exist
for supported option types. The macros also provide some type checking
as they initialise specific union members.
It should be possible to extend CFR support for more sophisticated
options like fan curve points. Feedback about this is highly
appreciated.

This commit rewrites the CPU topology initialization code to simplify
it and make it more maintainable.
The previous code used a complex set of if-else statements to
initialize the CPU topology based on the CPUID leaves that were
supported. This has been replaced with a simpler and more readable
function that follows the Intel Software Developer Manual
recommendation by prioritizing CPUID EAX=0x1f over CPUID EAX=0xb if
available.
The new code removes the need for separate functions to handle the
topology initialization for different CPUID leaves. It uses a static
array of bitfield descriptors to store the APIC ID descriptor
information for each level of the CPU topology. This simplifies the
code and makes it easier to add new levels of topology in the future.
The code populates the node ID based on the package ID, eliminating
the need for an extra function call.
