Julius Werner 37833fc4be qualcomm/common: Remove carriage returns from QcLib log
The memory log we get returned by QcLib contains Windows line endings
("\r\n"), while we prefer to have POSIX line endings in the CBMEM
console (just "\n"). Filter the '\r' character out when copying that log
into the CBMEM console to convert.

Jeremy Compostella 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.

Jeremy Compostella 79f2e1fc8b cbfstool: Make add-stage support multiple loadable segments
For x86 eXecute-In-Place (XIP) pre-memory `.data` section support, we
have to use an extra segment as the VMA/LMA of the data is different
than the VMA/LMA of the code.

To support this requirement, this patch makes cbfstool:
1. Allow the load of an ELF with an extra segment
2. Makes add-stage for XIP (cf. parse_elf_to_xip_stage()) write its
   content to the output binary.

To prevent the creation of unsuitable binaries, cbfstool verifies that
the LMA addresses of the segments are consecutives.

TEST=XIP pre-memory stages with a `.data` section have the `.data`
     section covered by a second segment properly included right after
     the code.

XSDT is primarily used to add new tables or to find the S3 resume vector.
However with QEMU coreboot does not generate most ACPI tables but takes
them from whatever QEMU provides. Qemu only creates an RSDT and lacks an
XSDT.

To keep the codebase simple with the assumption that XSDT is always
present, create an XSDT based on the existing RSDT and update the
address in RSDP.

Martin Roth 22e16db4c5 acpi/soundwire.[ch]: Fix dpn entry array overrun
In soundwire.h, SOUNDWIRE_DPN MIN  & MAX are set to 1 and 14. When
creating the dpn array, the length was set to MAX - MIN or 13, numbered
0 to 12.

When accessing the array, the code was bailing out if a value greater
than MAX was trying to be accessed, so the array was able to be overrun
by two structure lengths.

Fix this problem by:
1) Not subtracting the MIN value when creating the array, which does
waste a little space. If anyone wants to refactor the code to fix that,
please feel free.
2) Breaking out of the loop when the port is equal to the MAX port
number instead of just when it's greater than the max port number.

Mario Scheithauer 90e1346d51 mb/siemens/mc_ehl5: Enable PWM passthrough mode on PTN3460
The connected panel on this mainboard gets the PWM frequency directly
from the Elkhart Lake CPU. The PWM controls the brightness of the
backlight. Therefore, it is necessary to activate the PWM passthrough
mode in the PTN3460 eDP-to-LVDS bridge (see PTN3460 Programming Guide -
5. Configuration Registers).

Felix Held d30e081295 soc/amd/*/Makefile: drop wrong EFS diagrams
The EFS data structure diagrams in the Makefiles of Picasso and newer
SoCs were wrong, since the BIOS directory table pointer is in a
different location than shown in the diagram. Since the diagram also
wasn't that easy to understand and amdfwtool does all of that handling,
drop the wrong diagram from the Makefiles.

Patrick Rudolph f372c40b90 x86/tables: Upgrade error to critical
When more ACPI tables are written than space is available in CBMEM, the
buffer overflow corrupts other CBMEM tables and a successful boot is unlikely.

Upgrade the error message to critical and be more precise what to do.

Jeremy Compostella ba7a9eefcf soc/intel/common: Fix invalid MADT entries creation
commit f8ac3dda02 ("soc/intel/common:
Order the CPUs based on their APIC IDs") sort algorithnm walks all the
`cpu_info' entries without discarding empty ones.  Since `cpu_info' is
not initialized, the data that is used is undefined and it generally
results in the creation of invalid `Local x2APIC' entries in the
MADT ("APIC") ACPI table.

Depending on the X2APIC ID value the Linux kernel behavior
changes (cf. arch/x86/kernel/acpi/boot.c::acpi_register_lapic()):
1. If (int)ID >= MAX_LOCAL_APIC (32768), the Linux kernel discards the
   entry with the "skipped apicid that is too big" INFO level
   message.
2. If (int)ID < MAX_LOCAL_APIC (32768) (including negative) this data
   is taken into account and it can lead to undesirable behavior such
   as core being disabled as (cf. "native_cpu_up: bad cpu" ERROR
   kernel message).

TEST=Verified the MADT does not contain any invalid entries on rex.

Ruihai Zhou 2a6a79c706 drivers/mipi: sta_himax83102: Completely pull GPW to VGL before TP term
The sta_himax83102 panel sometimes shows abnormally flickering
horizontal lines. The front gate output will precharge the X point of
the next pole circuit before TP term starts, and wait until the end of
the TP term to resume the CLK. For this reason, the X point must be
maintained during the TP term. In abnormal case, we measured a slight
leakage at point X. This is because during the TP term, the GPW does not
fully pull the VGL low, causing the TFT to not be closed tightly.

To fix this, we completely pull GPW to VGL before entering the TP term.
This will ensure that the TFT is closed tightly and prevent the abnormal
display.
