933d2b0f13 lib: ramdetect: Add Kconfig PROBE_RAM
Previously ramdetect.c was compiled only for VENDOR_EMULATION.
Hence add Kconfig option PROBE_RAM which allows board outside
the scope of VENDOR_EMULATION to select and utilize  probe_ram
function to runtime detect usable RAM in emulation environment.

PROBE_RAM is default selected if VENDOR_EMULATION is set so
that existing boards under VENDOR_EMULATION scope are not
affected.

Other boards can explicitly select PROBE_RAM to use probe_ram.

TEST=Build mb/arm/rdn2 with PROBE_RAM selected & make sure
there is no any error.
Also checked qemu-aarch64 build to make sure build is success.

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).

c827c9b216 fmap: Map less space in fallback path without CBFS verification
This is a fixup to CB:78914 which inadvertently broke the RK3288 SoC.
Unfortunately we can only accommodate very little PRERAM_CBFS_CACHE in
the tiny SRAM for that chip, so we would not be able to map an entire
FMAP. Solve this problem for now by mapping less space when CBFS
verification is disabled, and disallowing CBFS verification on that SoC.

a2bc2540c2 Allow to build romstage sources inside the bootblock
Having a separate romstage is only desirable:
 - with advanced setups like vboot or normal/fallback
 - boot medium is slow at startup (some ARM SOCs)
 - bootblock is limited in size (Intel APL 32K)

When this is not the case there is no need for the extra complexity
that romstage brings. Including the romstage sources inside the
bootblock substantially reduces the total code footprint. Often the
resulting code is 10-20k smaller.

This is controlled via a Kconfig option.

TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.

ca71588620 fmap: Eliminate some impossible code paths
When the FMAP cache is enabled, it cannot fail in pre-RAM stages unless
flash I/O in general doesn't work. Therefore, it is unnecessary and a
waste of binary size to also link a fallback path for this case.
Similarly, once the cache is written to CAR/SRAM/CBMEM there should be
no way for it to become magically corrupted between boot stages. Many
other parts of coreboot blindly assume that persistent memory stays
valid between stages so there is no reason why this code should link in
extra fallback paths in case it doesn't.

This saves a little over 200 bytes per affected (uncompressed) stage on
aarch64.

682cb3b564 fmap: Die immediately on verification failure
A recent security audit has exposed a TOCTOU risk in the FMAP
verification code: if the flash returns a tampered FMAP during the first
setup_preram_cache(), we will abort generating the cache but only after
already filling the persistent CAR/SRAM region with the tampered
version. Then we will fall back into the direct access path, which could
succeed if the flash now returns the original valid FMAP. In later
stages, we will just use the data from the persistent CAR/SRAM region as
long as it looks like an FMAP without verifying the hash again (because
the hash is only linked into the initial stage).

This patch fixes the issue by just calling die() immediately if FMAP
hash verification fails. When the verification fails, there's no
recourse anyway -- if we're not dying here we would be dying in
cbfs_get_boot_device() instead. There is no legitimate scenario where
it would still be possible to continue booting after this hash
verification fails.

5bc5b1d024 fmap: Map full FMAP for verification in fallback path
The rarely-used fallback path for accessing the FMAP without a cache
currently only maps the FMAP header for the initial verify_fmap() call.
This used to be fine when we were just checking the magic number, but
with CBFS verification we may need to hash the entire FMAP.

Since this path is so rarely used anyway and the size difference only
has a practical impact on a few platforms, lets keep things simple and
just always map the whole FMAP.

226f51c765 x86: Add ramstage CBFS cache scratchpad support
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.

b7832de026 x86: Add .data section support for pre-memory stages
x86 pre-memory stages do not support the `.data` section and as a
result developers are required to include runtime initialization code
instead of relying on C global variable definition.

To illustrate the impact of this lack of `.data` section support, here
are two limitations I personally ran into:

1. The inclusion of libgfxinit in romstage for Raptor Lake has
   required some changes in libgfxinit to ensure data is initialized at
   runtime. In addition, we had to manually map some `.data` symbols in
   the `_bss` region.

2. CBFS cache is currently not supported in pre-memory stages and
   enabling it would require to add an initialization function and
   find a generic spot to call it.

Other platforms do not have that limitation. Hence, resolving it would
help to align code and reduce compilation based restriction (cf. the
use of `ENV_HAS_DATA_SECTION` compilation flag in various places of
coreboot code).

We identified three cases to consider:

1. eXecute-In-Place pre-memory stages
   - code is in SPINOR
   - data is also stored in SPINOR but must be linked in Cache-As-RAM
     and copied there at runtime

2. `bootblock` stage is a bit different as it uses Cache-As-Ram but
   the memory mapping and its entry code different

3. pre-memory stages loaded in and executed from
   Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`).

eXecute-In-Place pre-memory stages (#1) require the creation of a new
ELF segment as the code segment Virtual Memory Address and Load Memory
Address are identical but the data needs to be linked in
cache-As-RAM (VMA) but to be stored right after the code (LMA).

Here is the output `readelf --segments` on a `romstage.debug` ELF
binary.

    Program Headers:
      Type    Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
      LOAD    0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20
      LOAD    0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW  0x4

     Section to Segment mapping:
      Segment Sections...
       00     .text
       01     .data

Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they
are totally different for the Segment 1 holding the `.data`
section. Since we need the data section `VirtAddr` to be in the
Cache-As-Ram and its `PhysAddr` right after the `.text` section, the
use of a new segment is mandatory.

`bootblock` (#2) also uses this new segment to store the data right
after the code and load it to Cache-As-RAM at runtime. However, the
code involved is different.

Not eXecute-In-Place pre-memory stages (#3) do not really need any
special work other than enabling a data section as the code and data
VMA / LMA translation vector is the same.

TEST=#1 and #2 verified on rex and qemu 32 and 64 bits:
     - The `bootblock.debug`, `romstage.debug` and
       `verstage.debug` all have data stored at the end of the `.text`
       section and code to copy the data content to the Cache-As-RAM.
     - The CBFS stages included in the final image has not improperly
       relocated any of the `.data` section symbol.
     - Test purposes global data symbols we added in bootblock,
       romstage and verstage are properly accessible at runtime
     #3: for "Intel Apollolake DDR3 RVP1" board, we verified that the
     generated romstage ELF includes a .data section similarly to a
     regular memory enabled stage.

e.g. the 4G barrier of 32-bit space, this became only visible when
artificially setting an unusual, lower limit on a resource.

So, for the final placement, use `MIN(limit, range end)` instead
of the range's end alone.

In a similar fashion, for POSTCAR=n, loading ramstage from

b3485f3833 lib: Perform display init in normal boot mode if BMP_LOGO is set
Traditionally, display init during vboot "verified/secure/normal
boot mode" relies on the VB2_CONTEXT_DISPLAY_INIT. This is the
default behavior for vboot, meaning skip display init during verified
boot mode.

However, if the intention is to show the OEM splash screen (using
BMP_LOGO config) during boot, then the policy enforced by vboot needs
to be overridden. This can be done by setting the BMP_LOGO config flag.

If BMP_LOGO is not enabled, then the vboot policy will be followed and
display init will be skipped.

This change was made to allow OEMs to show their splash screen during
boot, even if the system is in verified/secure/normal mode.

e111de0752 lib: set up specific purpose memory as LB_MEM_SOFT_RESERVED
CXL (Compute Express Link) [1] is a cache-coherent interconnect
standard for processors, memory expansion and accelerators.

CXL memory is provided through CXL device which is connected
through CXL/PCIe link, while regular system memory is provided
through DIMMs plugged into DIMM slots which are connected to
memory controllers of processor.

With CXL memory, the server's memory capacity is increased.
CXL memory is in its own NUMA domain, with longer latency
and added bandwidth, comparing to regular system memory.

Host firmware may present CXL memory as specific purpose memory.
Linux kernel dax driver provides direct access to such differentiated
memory. In particular, hmem dax driver provides direct access to
specific purpose memory.

Specific purpose memory needs to be represented in e820 table as
soft reserved, as described in [2].

Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory)
resource that needs to be soft reserved.

Add soft_reserved_ram_resource macro to allow soc/mb code to add
memory resource as soft reserved.

explicit constant to codify that alignment, assertions to check it after
each entry, and adds explicit padding to the few entry structures that
were relying on compiler padding to return a correct sizeof() value.

50139d00bd lib: Hook up libhwbase in romstage
It's hidden behind the configuration option `CONFIG_ROMSTAGE_LIBHWBASE'.

This also adds some glue code to use the coreboot console for debug
output and our monotonic timer framework as timer backend.

Running Ada code in romstage and more particular libhwbase brings a few
challenges as global initialized variables are not supported in
Cache-As-Ram mode.

1. The libhwbase dynamic mmio driver implementation makes the Gnat
   compiler generate some global initialized variables.

   For this reason, when compiled for romstage or for romstage and
   ramstage the static mmio driver is enforced (`HWBASE_STATIC_MMIO').

2. The Gnat compiler generates elaboration functions to initialize
   program data at runtime. These elaboration functions are called by
   the romstage_adainit() function.

   The data references symbols suffixed by `_E'. Even though these
   symbols, at compilation time, do not contain any data and are
   filled with zeros, the Gnat compiler installs them in the .data
   section.

   Since these symbols are actually filled with zeros, it is safe to
   install them in the .bss section.

   cf. https://docs.adacore.com/gnat_ugn-docs/html/gnat_ugn/gnat_ugn/elaboration_order_handling_in_gnat.html#elaboration-code

5b89bf4666 lib: Introduce fw_config_get_field
In some cases, fw_config is used for ids like sar_id, sku_id etc.
To avoid calling fw_config_probe over and over, hence provide the
method to return the value then caller can use the switch case
instead of if else statement.

TEST=get fw_config field value on nivviks.
[INFO ]  fw_config get field name=DB_USB, mask=0x3, shift=0, value =0x1
