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.

This change:
- Standardizes the naming to reflect the actual content, which is a

- Aligns the code with the recent Kconfig changes that moved BMP_LOGO

logic directly into the FSP silicon initialization process. By checking
for critical conditions (e.g., low battery) within this callback after
FSP silicon initialization, the platform can initiate a controlled
shutdown before proceeding with further boot stages, preventing abrupt
shutdowns later in the boot process.

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.

How it approximately works:
(During a normal system run):
1. OS puts a capsule into RAM and calls UpdateCapsule() function of EFI
runtime
2. If applying the update requires a reboot, EFI implementation creates
a new CapsuleUpdateData* EFI variable pointing at the beginning of
capsules description (not data, but description of the data) and does
a warm reboot leaving capsule data and its description in RAM to be
picked by firmware on the next boot process
(After DEV_INIT:)
3. Capsules are discovered by checking for CapsuleUpdateData* variables
4. Capsule description in memory and capsule data is validated for
sanity
5. Capsule data is coalesced into a continuous piece of memory
(On BS_WRITE_TABLES via dasharo_add_capsules_to_bootmem() hook:)
6. Buffer with coalesced capsules is marked as reserved
(On BS_WRITE_TABLES via lb_uefi_capsules() hook:)
7. coreboot table entry is added for each of the discovered capsules
(In UEFI payload:)
8. CapsuleUpdateData* get removed
9. coreboot table is checked for any update capsules which are then
applied

coreboot needs to figure out top of memory to place CBMEM data. On some
non-x86 QEMU virtual machines, this is achieved by probing the RAM space
to find where the VM starts discarding data since it's not backed by
actual RAM. This behaviour seems to have changed on the QEMU side since
then, VMs using the "virt" model have started raising exceptions/errors
instead of silently discarding data (likely [1] for example) which has
previously broken coreboot on these emulation boards.
The qemu-aarch64 and qemu-riscv mainboards are intended for the "virt"
models and had this issue, which were mostly fixed by using exception
handlers in the RAM detection process [2][3]. But on 32-bit RISC-V we
fail to initialize CBMEM if we have 2048 MiB or more of RAM, and on
64-bit RISC-V we had to limit probing to 16383 MiB because it can run
into MMIO regions otherwise.
The qemu-armv7 mainboard code is intended for the "vexpress-a9" model VM
which doesn't appear to suffer from this issue. Still, the issue can be
observed on the ARMv7 "virt" model via a port based on qemu-aarch64.
QEMU docs for ARM and RISC-V "virt" models [4][5] recommend reading the
device tree blob it provides for device information (incl. RAM size).
Implement functions that parse the device tree blob to find described
memory regions and calculate the top of memory in order to use it in
mainboard code as an alternative to probing RAM space. ARM64 code
initializes CBMEM in romstage where malloc isn't available, so take care
to do parsing without unflattening the blob and make the code available
in romstage as well.

<stdio.h> header is used for input/output operations (such as printf,
scanf, fopen, etc.). Although some input/output functions can manipulate
strings, they do not need to directly include <string.h> because they
are declared independently.

This adds some helper functions for FDT, since more and more mainboards
seem to need FDT nowadays. For example our QEMU boards need it in order
to know how much RAM is available. Also all RISC-V boards in our tree
need FDT.
This also adds some tests in order to test said functions.

This prevents potential errors from mismatched size assumption.
