3c7bbde4fd drivers/intel/fsp2_0: Release bmp_logo during OS_PAYLOAD_LOAD stage
bmp_load_logo() loads the custom logo.bmp file into CBMEM. This cbmem
buffer is released after FSP-S init is complete. In certain platforms,
the logo file is displayed during PCI enumeration.  This means the logo
buffer is used after it is released. Fix this issue by releasing the
logo buffer when the coreboot has finished loading payload. During S3
scenario CBMEM is locked, bmp logo is not loaded and hence the release
is a no-op.

d4d6d6c8d0 drivers/intel/dptf: Add DCFG support
After final production, it's possible by setting particular
bit using DCFG the OEM/ODM locks down thermal tuning beyond
what is usually done on the given platform.

In that case user space calibration tools should not try
to adjust the thermal configuration of the system.

By adding new DCFG (Device Configuration) it allows the
OEM/ODM to control this thermal tuning mechanism. They can
configure it by adding dcfg config under overridetree.cb file.
The default value for all bits is 0 to ensure default behavior
and backwards compatibility.

For an example if Bit 0 being set represents Generic DTT UI
access control is disabled and Bit 2 being set represents DTT
shell access control is disabled.
Each bit represents different configuration access control
for DTT as per BIOS specification document #640237.

It also gives the provision for user space to check the current
mode. This mode value is based on BIOS specification document
number #640237.

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.

2. The `FSPM_ARCH2_UPD' and `FSPS_ARCH2_UPD' data structures must be

3. It support 64-bits FSP but 64-bits support will be provided by

Note that similarly to what is done for silicon initialization,
timestamps and post-codes are used during the memory initialization
multi-phase.

let's rename it 'platform_fsp_silicon_multi_phase_init_cb' to avoid
any confusion.

0201d989f2 drivers/intel/fsp: Work around multi-socket Xeon-SP pipe init bug
Starting with Intel CPX there is a bug in the reference code during
the Pipe init. This code synchronises the CAR between sockets in FSP-M.
This code implicitly assumes that the FSP heap is right above the
RC heap, where both of them are located at the bottom part of CAR.

Work around this issue by making that implicit assumption done in FSP
explicit in the coreboot linker script and allocation.

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.

074fbfe8df drivers/intel/gma: Add missing parentheses to brightness ACPI
Commit d252776668 ("tree: Replace And(a,b) with ASL 2.0 syntax")
replaced two instances of `And(var, mask) == 0` with `var & mask == 0`.
This expression needs parentheses - `(var & mask) == 0`.

Without parentheses, it is always false, since the masks are nonzero
(`var & (mask == 0)`; `var & 0`; `0`).

This caused brightness changes on Intel GMA to take longer than
normal since the status was never checked.  The brightness would
change immediately, but another brightness change could not occur until
the first change timed out.

This was most noticeable in KDE, which waits for the brightness change
to complete before accepting another brightness up/down keypress.
Tapping brightness up/down repeatedly would take much longer to reach
max/min brightness due to many presses being ignored.

It is noticeable in GNOME as well but less obvious.  Tapping brightness
up/down repeatedly would handle all keypresses, but the display's
actual brightness would lag behind and skip some intermediate steps.

I tested both Librem 13v2 and Librem 14, as far as I know this would
apply to all systems configuring brightness with Intel GMA.

Test: Verify brightness keys respond quickly again on Librem 13v2 / 14.

This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:

CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,

This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.

It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

eb834d9d13 drivers/intel/fsp2_0: Support embedding a second FSP-M/FSP-S
Support embedding a second FSP-M/FSP-S binary for an SoC that can
select one at runtime.

Comet Lake v1 and v2 are different steppings of the same SKUs, but they
require different FSP binaries.  Supporting both in a single build
requires embedding both FSPs and selecting one at runtime based on the
CPUID.  This is desirable for a product that may have different CPU
steppings but is not otherwise differentiated enough for a separate
firmware build.

An SoC can select PLATFORM_USES_SECOND_FSP to indicate that two FSP-M/
FSP-S binaries are required.  Implement soc_select_fsp_m_cbfs() and
soc_select_fsp_s_cbfs() to choose one based on platform-specific
criteria.  For Comet Lake, the first FSP is CML v1 and the second is
CML v2, but in principle a platform could define any meaning for the
first and second FSP.

FSP-T is not affected, only one FSP-T can be embedded if FSP_CAR is
used.

Only one set of FSP headers is used, which is sufficient for Comet Lake
v1/v2; their headers are equivalent.

ADD_FSP_BINARIES, FSP_USE_REPO, and FSP_FULL_FD are supported for both
sets of FSP-S/FSP-M but cannot be configured separately, both use the
same configuration.

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,
