6e303aa89b cbfs: Allow controlling decompression of unverified files
This patch adds a new Kconfig that controls whether CBFS APIs for
unverified areas will allow file decompression when CBFS verification is
enabled. This should be disallowed by default because it exposes the
attack surface of all supported decompression algorithms. Make
allowances for one legacy use case with CONFIG_SOC_INTEL_CSE_LITE_
COMPRESS_ME_RW that should become obsolete with VBOOT_CBFS_INTEGRATION.

3c2cdb6e57 lib: Support localized text of memory_training_desc in ux_locales.c
To support the localized text, we need to get the locale id by vboot
APIs and read raw string content file: preram_locales located at either
RO or RW.

The preram_locales file follows the format:
  [string_name_1] [\x00]
  [locale_id_1] [\x00] [localized_string_1] [\x00]
  [locale_id_2] [\x00] [localized_string_2] ...
  [string_name_2] [\x00] ...

This code will search for the correct localized string that its string
name is `memory_training_desc` and its locale ID matches the ID vb2api
returns. If no valid string found, we will try to display in English
(locale ID 0).

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.

using LZMA compression for FSP-M, we still need the LZMA decompression
to be present, so update when the Makefile includes the LZMA decoder.

9a9b2778a1 coreboot_tables: Make existing alignment conventions more explicit
There seem to be some recurring vague concerns about the alignment of
coreboot table entries. While the existing implementation has been
producing tables with a well-defined alignment (4 bytes) for a long
time, the code doesn't always make it very clear. This patch adds an
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

9948c521a6 lib/coreboot_table: Simplify API to set up lb_serial
Instead of having callbacks into serial console code to set up the
coreboot table have the coreboot table code call IP specific code to get
serial information. This makes it easier to reuse the information as the
return value can be used in a different context (e.g. when filling in a
FDT).

This also removes boilerplate code to set up lb_console entries by
setting entry based on the type in struct lb_uart.

d96ca24652 cbfs/vboot: Adapt to new vb2_digest API
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.

Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:

Updating from commit id 18cb85b5:
    2load_kernel.c: Expose load kernel as vb2_api

This also reduces the ramstage by 448 bytes on google/vilboz.

pointer so add it to cbfs.

Note that on Intel APL this file is not used, which is why the
bootblock still needs to contain the pointer in the ARCH_X86 part.
It is not worth it to add logic to specifically deal with APL as this is
a legacy feature anyway.

For AMD non-car platform this fixes cbfs access in SeaBIOS.
