Puff-based Chromeboxes use a LSPCON for HDMI 2.0 output, but no driver
exists or is needed for Windows. Use the devicetree hidden keyword to
set the ACPI status to hidden for these devices, to prevent unknown
devices from being listed in Windows Device Manager.
TEST=build/boot Win11 on google/wyvern, verify no unknown devices in
Windows Device Manager for either LSPCON device.

This commit streamlines code and strengthens common code robustness
by moving the following SoC-layer functions to the common layer:
- sa_get_mmcfg_size: Retrieves the MMIO (Memory-Mapped I/O)
configuration space size by reading offset
0x60 of the PCI Host Bridge (D0:F0).
- sa_get_dsm_size: Calculates the size of the DSM (Device Stolen
Memory) by reading offset 0x50 of the PCI
Host Bridge (D0:F0) to determine pre-allocated
memory for the IGD (Integrated Graphics Device).
- sa_get_gsm_size: Calculates the size of the GSM (Graphics Stolen
Memory) by reading offset 0x52 of the PCI Host
Bridge (D0:F0).
- sa_get_dpr_size: Determines the size of the DMA Protection
Range (DPR) by reading offset 0x5C of the PCI
Host Bridge (D0:F0).

adds the code to fix up the clock configuration depending on dxio
descriptors. Also this brings picasso in line with cezanne, mendocino

The name LEDLOGO comes from schematics. It's the red indicator, embedded
in the dot of the 'i' of the ThinkPad logo on laptop's lid.
In vendor firmware, this led starts fading in-and-out, or, in other
words, pulsing, when laptop is put to S3. It helps to determine whether
the laptop is in S3 just by taking a look at the logo.
As of now, coreboot doesn't do anything with this particular indicator,
it's always in enabled (on) state, which is not very convenient.
This patch fixes it.
Tested on T440p.

gpp_clk_setup code in most AMD SoC is similar and it can moved to common
code. The only thing which is SoC dependent in this function is the SoC
config, hence keep it in SoC code and move everything else in new
gpp_clk_setup_common function which is in soc/amd/common. Picasso and
Glinda don't have pcie_gpp_dxio_update_clk_req_config fixup function so
they are addressed in later patches.

There is an existing issue for nissa where wake up from RTC wake is not working during suspend_stress_test.
The phenomenon of the issue is that after pulling out the stylus, can see an interrupt storm occurs, checking through:
"cat /proc/interrupts | grep acpi".
When the counter of interrupt is greater than a certain value, "Disabling IRQ #9" will occur, so RTC wake is not working.
Reference: https://review.coreboot.org/c/coreboot/+/65086
This patch skips the locking for GPP_F15 to allow kernel to
configure it later. The interrupt storm of acpi disappears.

While introducing driver support for QEMU Cirrus display device, commit
7905f9254ebc ("qemu: cirrus native video init") also explicitly adds
VGA I/O functions into ramstage class when Bochs display driver support
is enabled.
Later, commit db7d04d1b753 ("qemu: Support textmode gfx init.") makes
the related config option select CONFIG_VGA, which also adds the same
file into ramstage class (among other things) in another Makefile.
Doing this twice is unnecessary. Remove the addition based on the Bochs
display driver's config option. Adding it based on CONFIG_VGA is
clearer, and future patches will try to support a Bochs display without
legacy VGA support on non-x86 architectures.

It seems that we have some applications where we need to calculate a GCD
in 64 bits. Now, we could instantiate the algorithm multiple times for
different bit width combinations to be able to use the most efficient
one for each problem... but considering that the function usually only
gets called once per callsite per stage, and that software emulation of
64-bit division on 32-bit systems doesn't take *that* long either, we
would probably usually be paying more time loading the second instance
of the function than we save with faster divisions. So let's just make
things easy and always do it in 64-bit and then nobody has to spend time
thinking on which version to call.

In case printk does not work the current exception handler will print a
simple "!" to notify the developer that coreboot is actually there but
something went wrong.
The "!" can be quite confusing when it actually happens that printk does
not work. Since "!" doesn't really say much (if you don't know the
exception arm64 code) the developer (like me) can easily assume that
something went wrong while configuring clocks or baud rate of UART,
since the output seemingly does not seem to make sense.
This adds a little bit more output to assure the developer that what was
printed was actually intended to be printed. Therefore it prints
"EXCEPT" which assures the developer that this was intended output.
It also adds a comment above so that developer can more easily grep
for this message.
It has intentionally not been written as:
```
const char *msg = "\r\n!EXCPT!";
while (*msg)
__uart_tx_byte(*msg++);
```
because in this case the compiler will generate code that will place
`msg` somewhere in bootblock and the code will try to access this using
a memory address. In rare cases (if you link bootblock at the wrong
address) this memory address can be wrong and coreboot will not print
the message. Using individual calls to `__uart_tx_byte` ensures that the
compiler will generate code which directly puts the character bytes into
the argument register without referencing a variable in bootblock.

Drop the unneeded data_fabric_set_mmio_np function and the corresponding
SOC_AMD_COMMON_BLOCK_DATA_FABRIC_NP_REGION Kconfig symbol. In systems
with only one FCH, its MMIO region will be subtractively decoded and
there's no need to add a non-posted data fabric MMIO region after the
FSP/openSIL has already configured the data fabric decode windows. In
systems with more than one FCH, openSIL will already take care of
initializing everything for the additional FCH, so we also won't need to
do anything in that case. Since dropping this function also removes both
data_fabric_print_mmio_conf calls before and after adding the unneeded
non-posted MMIO region, replace the data_fabric_set_mmio_np call with a
data_fabric_print_mmio_conf call to still print the data fabric MMIO
decode regions set up by the FSP/openSIL.

Back in the days of the APIC bus, the IOAPIC IDs mustn't overlap with
the LAPIC IDs (0 to CONFIG_MAX_CPUS - 1), but since the IOAPIC and LAPIC
nowadays talk to each other via the system bus, an IOAPIC ID of 0 is
valid. When set_ioapic_id gets called with an IOAPIC ID of 0, it skipped
writing the IOAPIC ID to the corresponding IOAPIC register, so the code
was relying of the register having the expected default value of the
IOAPIC IO 0 for things to work as expected. The case of the IOAPIC ID
being 0 is the most common case in coreboot, since that's what
register_new_ioapic_gsi0 will end up doing. Fix this issue by not making
the io_apic_write call conditional on ioapic_id being non-zero. The only
southbridge that doesn't call register_new_ioapic_gsi0, calls
set_ioapic_id with the IOAPIC ID 2 for which this won't cause any
changes in behavior.

The MTCL function provides a country list to the Linux kernel via an
ACPI function in SSDT for MediaTek WiFi chipsets that are capable of
operating on the 6GHz band. The country list is used to selectively
disable 6GHz and 5.9GHz operation based on the country the device is
operating in.
The function needs to read a binary file and send it as a package via
the MTCL method in SSDT for PCIe WiFi with MediaTek chipsets.
Change Summary:
* Add src/drivers/wifi/generic/mtcl.c to abstract functionaltity related
to MTCL
* Add write_mtcl_aml function to convert the byte data into the format
expected by the MTCL functionality in the Linux kernel.
* Add validate_mtcl function to validate that the byte data read in
from a file is in the expected format.
* Add write_mtcl_function function to read a binary file called
"wifi_mtcl".bin" from cbfs, then call validate_mtcl to verify that
it is in an expected format, and if so write the aml via acpigen
* Add config flag DRIVERS_MTK_WIFI to src/drivers/wifi/generic in order
to include MediaTek WiFi specific functionality
* Add config flag USE_MTCL which depends on DRIVERS_MTK_WIFI and
enables including the specific ACPI function defined in SSDT
* Add config flag CONFIG_MTCL_CBFS_FILEPATH which depends on
DRIVERS_MTK_WIFI which enables configuring the file to add as
"wifi_mtcl.bin"
* Add a call to write_mtcl_function to src/drivers/wifi/generic/acpi.c
to include the MTCL function in SSDT for MTK WiFi devices when
USE_MTCL is enabled.
* Add MediaTek VID to src/include/device/pci_ids.h.

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.

The configuration of the PCIe clock generators in the FCH was moved from
the FSP to coreboot, since all registers are documented. This
initialization is however tightly integrated in the rest of the PCIe
init code inside the reference code. In the FSP case, this code was
manually removed. openSIL will do that part of the initialization so
that there's no coreboot-specific change needed in openSIL. This will
also avoid the problems caused by mismatching configurations done by the
coreboot code and the PCIe init part of the reference code.

Provide 3 separate functions for each openSIL time point instead of one,
so that we don't need the xSIM-api header file to be included in
opensil.h to decouple the coreboot code more form the openSIL code. This
will allow to create an openSIL stub implementation to already get most
of the coreboot-side SoC code in place before the openSIL source code is
done and released.

When a device with no resource is passed it will keep overwriting
the current slot. Remove the conditional and allow a PCI device
to not have any resources.
This is particular useful for the next commits that makes use
of the PCI resource store to pass UBOX devices to SMM that allow
to lock-down SMM from within an SMI handler. Those devices do
not have any resources and cannot be hardcoded in SMM as their
PCI segment group and bus number varies depending on socket
count, CPU discovery and configuration.

Commit d25277666829 ("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.

Now that the SoC-specific memory map is reported on the domain device
instead of the northbridge device, factor out the
read_soc_memmap_resources function from root_complex.c to new memmap.c
file. For now each SoC still has its own memmap.c file, but the plan is
to eventually have a common implementation that works for all AMD family

between the FSP and the openSIL integration though.

Since reporting the PCI ECAM MMCONF MMIO region and the IO ports for the
legacy PCI config space access is needed on all AMD SoCs, implement a
common add_pci_cfg_resources function that reports both and gets called
from amd_pci_domain_read_resources and don't report those in the SoC-

the IO ports used for the legacy PCI config space access get reserved.

In order to use PCI drivers for UBOX devices, locating UBOX devices
by vendor and device IDs and replacing device access by specifying
S:B:D:F numbers, add a PCI domain for the UBOX stacks and let the
PCI enumerator index all devices.
Since there are no PCI BARs on the UBOX bus the PCI locator doesn't
have to assign resources on those buses.
Once all PCI devices on the UBOX stack can be located without knowing
their UBOX bus number and PCI segment the Xeon-SP code can fully
enable the multi PCI segment group support.

Macros can be confusing on their own; hiding commas make things worse.
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.

With Cr50, the GPIO EC_IN_RW is used to determine whether EC is trusted. However, With the switch to Ti50, it is determined by Ti50's boot mode. If the boot mode is TRUSTED_RO, the VB2_CONTEXT_EC_TRUSTED flag will be set in check_boot_mode(). Therefore in the Ti50 case get_ec_is_trusted() can just return 0.
The current code of get_ec_is_trusted() only checks the GPIO, which
causes the EC to be always considered "trusted". Therefore, correct the return value to 0 for TPM_GOOGLE_TI50.

usually run into the case (see: not too many die() instances going

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

Multiple links are unused throughout the tree and make the code more
confusing as an iteration over all busses is needed to get downstream
devices. This also not done consistently e.g. the allocator does not
care about multiple links on busses. A better way of dealing multiple
links below a device is to feature dummy devices with each their
respective bus.
This drops the sconfig capability to declare the same device multiple
times which was previously used to declare multiple links.
