32085aec84 lib: Replace 'unsigned long int' by 'unsigned long'
As suggested by the linter:

Prefer 'unsigned long' over 'unsigned long int' as the int is unnecessary

91fe658714 drivers/option: Add forms in cbtables
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.

bd9370d775 drivers/efi/uefi_capsules.c: coalesce and store UEFI capsules
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

Dying is appropriate if cbmem is not found as it is essential to the

6bdc3becfd util/sconfig: Probe device when fw_config is unprovisioned
When fw_config is unprovisioned (eg. in the factory), devices that do
not have any probe list are enabled by default and those that have probe
list are disabled. On mainboards that support multiple types of boot
critical devices (eg. storage) through probing fw_config, all of
them are disabled when fw_config is unprovisioned. Hence the devices do
not boot to OS. Add sconfig fw_config rule `probe unprovisioned` to
enable such devices when fw_config is unprovisioned.

BUG=None
TEST=Build Brox firmware and boot to OS when fw_config is unprovisioned.

1a8b9c20f8 drivers/efi: add optional ESRT-friendly coreboot table tag
EFI System Resource Table (ESRT) is an informational structure that

chiefly used to perform firmware updates.

New CONFIG_DRIVERS_EFI_FW_INFO is off by default, enabling it adds
DRIVERS_EFI_FW_{GUID,VERSION,LSV} to be used to specify firmware
version/update information.

Existing forms of versions wouldn't be sufficient because there is no
universal way of converting string versions to 32-bit unsigned integers
and there are no GUIDs or lowest supported versions.

efad423f84 lib/jpeg: avoid calling malloc and free
Since commit 1d029b40c9 ("lib/jpeg: Replace decoder with Wuffs'
implementation"), a relatively large heap allocation is needed to decode
many JPEGs for use as work area. The prior decoder did not need this,
but also had many limitations in the JPEGs it could decode, was not as
memory-safe and quickly crashed under fuzzing.

This commit keeps using Wuffs' JPEG decoder, but it no longer requires
any heap allocation (and thus configuring the heap size depending on how
big a bootsplash image you want to support).

Note that in the existing libpayload implementation, these functions

check and that other major libc implementations (e.g. glibc [1]) don't
seem to do that, the new functions also don't perform the NULL check.

af0d4bce65 region: Introduce region_create() functions
We introduce two new functions to create region objects. They allow us
to check for integer overflows (region_create_untrusted()) or assert
their absence (region_create()).

This fixes potential overflows in region_overlap() checks in SMI
handlers, where we would wrongfully report MMIO as *not* overlapping
SMRAM.

Also, two cases of strtol() in parse_region() (cbfstool),  where the
results were implicitly converted to `size_t`, are replaced with the
unsigned strtoul().

FIT payload support is left out, as it doesn't use the region API
(only the struct).

377157c7fb device_tree: Add function to get top of memory from a FDT blob
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.

33079b8174 lib/device_tree: Add some FDT helper functions
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.

b3e336c51d treewide: Move stdlib.h to commonlib
This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since
all code is BSD licensed anyway.
It also moves some code from libpayloads stdlib.h to
commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is
useful for a subsequent commit that adds devicetree.c into commonlib.

Also we don't support DMA on arm platforms in coreboot (only libpayload)
therefore `dma_malloc()` has been removed and `dma_coherent()` has been
moved to architecture specific functions. Any architecture that tries to
use `dma_coherent()` now will get a compile time error. In order to not
break current platforms like mb/google/herobrine which make use of the
commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a
stub has been added to arch/arm64/dma.c.

67166a7eb2 lib/program.ld: Make (NOLOAD) and to_load more explicit
(NOLOAD) indicates that the section occupies no space in the file, but
does take up space in memory during process execution. It's typically
used for bss sections which contain uninitialized global/static
variables.

to_load makes sure the section is part of the program headers. This is
needed for instance with relocatable stages to know how much memory the
program will use.

Although the BFD linker makes some good guesses making this a NOOP,
other linkers like LLD need to mark these sections more explicitly.
