409860687b security/vboot: Set VBOOT_ALWAYS_ENABLE_DISPLAY if BMP_LOGO
If BMP_LOGO is set, currently display_init_required() will always return
1, so that platform code will always initialize display. However, that
information isn't passed to vboot, which may result in unnecessary extra
reboots, for example when the payload needs to request display init (by
vb2api_need_reboot_for_display()).

Since there is already a Kconfig option VBOOT_ALWAYS_ENABLE_DISPLAY to
tell vboot that "display is available on this boot", enable it by
default if BMP_LOGO is set.

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.

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.

(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

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.

in order for the section to have the NOBITS, rather than PROGBITS

de37109767 lib: Move IP checksum to commonlib
This patch moves the IP checksum algorithm into commonlib to prepare for
it being shared with libpayload. The current implementation is ancient
and pretty hard to read (and does some unnecessary questionable things
like the type-punning stuff which leads to suboptimal code generation),
so this reimplements it from scratch (that also helps with the
licensing).

This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
series for architecture-specific optimization.

c59426f60d malloc/memalign: Return NULL if the request is too large
It's what this function family is defined to do, we currently don't
usually run into the case (see: not too many die() instances going
around), it's more useful to try to recover, and the JPEG parser can run
into it if the work buffer size exceeds the remaining heap, whereas its
sole user (the bootsplash code) knows what to do when seeing a NULL.

Use xmalloc() if you want an allocation that either works or dies.

tl;dr: That code path isn't usually taken. Right now it crashes. With
this patch it _might_ survive. There is a use-case for doing it like
that now.

This patch also introduces three new Kconfigs:

 - CHROMEOS_LOGO_PATH
 - CHROMEBOOK_PLUS_LOGO_PATH
which allow users to enable the fw splash screen feature in the
vendorcode. Previously, we were using the BMP_LOGO Kconfig in
drivers/intel/fsp2_0, but we didn't want the top level Kconfigs to be
located inside the architecture specific files.

ed0647a850 src/lib: Add memory/time saving special case for ramstage caching
When caching the ramstage for suspend/resume, we copy the entire image
as it resides in RAM. The last part of that, CONFIG_HEAP_SIZE bytes, is
the heap that will be reinitialized when the ramstage is started again.

As such, copying doesn't make sense and complicates HEAP_SIZE
configuration (because it needs to fit the space-constrained cache
location) and costs time and space. Therefore, skip the heap.

Side notes:
- When building with ASAN, program.ld indicates that it will allocate
  some more space after the heap. This is not a problem, we just copy
  an ASAN-sized copy of the heap.
- Heap use is managed in src/lib/malloc with statically allocated
  variables. Because ramstage is cached before it's executed, these
  values will be reset to their compile-time default values, too.

1d029b40c9 lib/jpeg: Replace decoder with Wuffs' implementation
To quote its repo[0]: Wuffs is a memory-safe programming language (and
a standard library written in that language) for Wrangling Untrusted
File Formats Safely. Wrangling includes parsing, decoding and encoding.

It compiles its library, written in its own language, to a C/C++ source
file that can then be used independently without needing support for
the language. That library is now imported to src/vendorcode/wuffs/.

This change modifies our linters to ignore that directory because
it's supposed to contain the wuffs compiler's result verbatim.

Nigel Tao provided an initial wrapper around wuffs' jpeg decoder
that implements our JPEG API. I further changed it a bit regarding
data placement, dropped stuff from our API that wasn't ever used,
or isn't used anymore, and generally made it fit coreboot a bit
better. Features are Nigel's, bugs are mine.

This commit also adapts our jpeg fuzz test to work with the modified
API. After limiting it to deal only with approximately screen sized
inputs, it fuzzed for 25 hours CPU time without a single hang or
crash. This is a notable improvement over running the test with our
old decoder which crashes within a minute.

Finally, I tried the new parser with a pretty-much-random JPEG file
I got from the internet, and it just showed it (once the resolution
matched), which is also a notable improvement over the old decoder
which is very particular about the subset of JPEG it supports.

In terms of code size, a QEmu build's ramstage increases
from 128060 bytes decompressed (64121 bytes after LZMA)
  to 172304 bytes decompressed (82734 bytes after LZMA).
