Currently coreboot interprets TCSS port number as per physical port
number while EC abstracts port number and provides indices as port
number. For example, if TCSS port 1 and 3 are enabled on the board,
coreboot will interpret port numbers as 0 and 2, but since only 2 ports
are enabled in the system EC will assign port numbers as 0 and 1.
This creates a port number mismatch while communicating between EC and
coreboot. This patch addresses issue where SoC can implement function
to map correct EC port as per port enabled in mainboard.
BUG=b:207057940
BRANCH=None
TEST=Check if code compiles successfully. Functionality will work once
function is implemented in SoC code.

The current implementations of edid_read() and segments_edid_read() have
a few problems:
1. The type of variable `c` is incorrect, not matching the return type
of sp_tx_aux_rd(). In addition, the meaning of `c` is unknown.
2. It is pointless to do `cnt++` when sp_tx_aux_rd() fails.
3. These two functions ignore the return value of
anx7625_reg_block_read().
4. In segments_edid_read(), anx7625_reg_write() might return a positive
value on failure.
Fix all of the 4 issues, and modify the code to be closer to kernel
5.10's implementation (drivers/gpu/drm/bridge/analogix/anx7625.c). Note
that, however, unlike in kernel, anx7625_reg_block_read() here doesn't
return the number of bytes. On success, 0 is returned instead.
In addition, following coreboot's convention, always return negative
error codes. In particular, change the return value to -1 for
edid_read() and segments_edid_read() on failure.

The SMMSTORE_IN_CBFS option was just meant as a workaround for an
attempt to backport SMMSTORE into older Chromebooks that never actually
happened. All current and future users of coreboot should be using
SMMSTORE in an FMAP region. The APIs needed for SMMSTORE_IN_CBFS clash
with the CBFS rdev isolation needed for CBFS_VERIFICATION, so let's just

So far POST codes were mapped on IO port 0x80 inside the NC FPGA which
was connected via the LPC bus to the host CPU. On recent x86 generations
the LPC bus was replaced with eSPI and not all Siemens boards have the
eSPI routed to the NC FPGA. In order to have POST codes visible on those
boards the display is accessible via PCI in addition.
This patch adds the feature of sending the POST codes to the NC FPGA via
a PCI mapped register.

As per MP service specification, EDK2 is allowed to specify the mode
in which a 'func' routine should be executed on APs.
`SingleThread` sets to 'true' meaning to execute the function one by
one (serially) or sets to 'false' meaning to execute the function
simultaneously.
MP service API `StartupAllAPs` was designed to pass such options as
part of function argument.
But another MP service API `StartupAllCPUs` doesn't specify any such
requirement. Running the `func` simultaneously on APs results in
a coherency issue (hang while executing `func`) due to lack of
acquiring a spin lock while accessing common data structure in
multiprocessor environment.

not get optimized out at build time because the devicetree gets
compiled into a linked list. As this code pulls in some heavy ACPI

makes sense to optimize out this code using a Kconfig constant.

There are manual timeout-loops which use a fixed value and udelay().
In all cases there is a debug printk() inside this loop which, when
enabled, takes way longer than the counted microsecond delay. This
leads to the result that e.g. a 1 second delay takes nearly an eternity
if the debug messages are enabled due to the longer function execution
time.
This patch uses the stopwatch scheme for the timeout-loops which still
makes sure that the timeout period is maintained while it takes longer
function calls like printk() into account. In order to keep the minimum
delay between two register accesses on the TPM keep the udelay(1)-call.
TEST=Enable TPM debug messages on a board where the TPM hits a timeout
by failure and make sure that the debug messages occur in the log
just in the timeout period. It still works as expected if the debug
messages are disabled.

There is the wrong register offset printed in the debug log when the
data register is written:
'lpc_tpm: Write reg 0x18 with 0xnn' should be
'lpc_tpm: Write reg 0x24 with 0xnn' for data FIFO access.
This can be confusing when searching for issues with the help of the
TPM debug messages since the code itself is correct. Fix this error.

On AArch64 platforms, GIC initialization is generally the job of Trusted
Firmware and shouldn't be necessary in coreboot. Only the ancient T210
platform (which was started before we had decided on using Trusted
Firmware) calls this code, and even there they have a comment wondering
"do we still need this?". I'm just gonna assume (without testing because
that board is ancient and I'm lazy) that they don't, and that the TF GIC
initialization[1] is sufficient here. Remove this obsolete driver.

FspMultiPhaseSiInit API was introduced with FSP 2.2 specification
onwards. EnableMultiPhaseSiliconInit is an arch UPD also introduced
as part of FSP 2.2 specification to allow calling FspMultiPhaseSiInit
API.
However, some platforms adhere to the FSP specification but
don't have arch UPD structure, for example : JSL, TGL and Xeon-SP.
Out of these platforms, TGL supports calling of FspMultiPhaseSiInit
API and considered EnableMultiPhaseSiliconInit as a platform-specific
UPD rather than an arch UPD to allow calling into FspMultiPhaseSiInit
API.
It is important to ensure that the UPD setting and the callback for
MultiPhaseInit are kept in sync, else it could result in broken
behavior e.g. a hang is seen in FSP if EnableMultiPhaseSiliconInit
UPD is set to 1 but the FspMultiPhaseSiInit API call is skipped.
This patch provides an option for users to choose to bypass calling
into MultiPhaseSiInit API and ensures the EnableMultiPhaseSiliconInit
UPD is set to its default state as `disable` so that FSP-S don't
consider MultiPhaseSiInit API is a mandatory entry point prior to
calling other FSP API entry points.
List of changes:
1. Add `FSPS_HAS_ARCH_UPD` Kconfig for SoC to select if
`FSPS_ARCH_UPD` structure is part of `FSPS_UPD` structure.
2. Drop `soc_fsp_multi_phase_init_is_enable()` from JSL and Xeon-SP
SoCs, a SoC override to callout that SoC doesn't support calling
MultiPhase Si Init is no longer required.
3. Add `FSPS_USE_MULTI_PHASE_INIT` Kconfig for SoC to specify if
SoC users want to enable `EnableMultiPhaseSiliconInit` arch UPD (using
`fsp_fill_common_arch_params()`) and execute FspMultiPhaseSiInit() API.
4. Presently selects `FSPS_USE_MULTI_PHASE_INIT` from IA TCSS common
code.
5. Add `fsp_is_multi_phase_init_enabled()` that check applicability of
MultiPhase Si Init prior calling FspMultiPhaseSiInit() API to
honor SoC users' decision.
6. Drop `arch_silicon_init_params()` from SoC as FSP driver (FSP 2.2)
would check the applicability of MultiPhase Si Init prior calling
FspMultiPhaseSiInit() API.
Additionally, selects FSPS_HAS_ARCH_UPD for Alder Lake as Alder Lake
FSPS_UPD structure has `FSPS_ARCH_UPD` structure and drops
`arch_silicon_init_params()` from SoC
`platform_fsp_silicon_init_params_cb()`.
Skip EnableMultiPhaseSiliconInit hardcoding for Tiger Lake and uses
the fsp_is_multi_phase_init_enabled() function to override
EnableMultiPhaseSiliconInit UPD prior calling MultiPhaseSiInit FSP API.
TEST=EnableMultiPhaseSiliconInit UPD is getting set or reset based on
SoC user selects FSPS_USE_MULTI_PHASE_INIT Kconfig.

The call to the `get_smbios_data` device operation is followed by
calls to unconditional default functions, which lacks flexibility.
Instead, have devices that implement `get_smbios_data` call these
default functions as needed.
Most `get_smbios_data` implementations are in mainboard code, and are
bound to the root device. The default functions only operate with PCI
devices because of the `dev->path.type != DEVICE_PATH_PCI` checks, so
calling these functions for non-PCI devices is unnecessary. QEMU also
implements `get_smbios_data` but binds it to the domain device, which
isn't PCI either.

Our MIPI panel initialization framework differentiates between DCS and
GENERIC commands, but the exact interpretation of those terms is left to
the platform drivers. In practice, the MIPI DSI transaction codes for
these are standardized and platforms always need to do the same
operation of combining the command length and transfer type into a
correct DSI protocol code. This patch factors out the various
platform-specific DSI protocol definitions into a single global one and
moves the transaction type calculation into the common panel framework.
The Qualcomm SC7180 implementation which previously only supported DCS
commands is enhanced to (hopefully? untested for now...) also support
GENERIC commands. While we're rewriting that whole section also fix some
other issues about how exactly long and short commands need to be passed
to that hardware which we identified in the meantime.

Existing SAR infrastructure supports only revision 0 of the SAR tables.
This patch modifies it to extend support for intel wifi 6 and wifi 6e
configurations as per the connectivity document:
559910_Intel_Connectivity_Platforms_BIOS_Guidelines_Rev6_4.pdf
The SAR table and WGDS configuration block sizes were static in the
legacy SAR file format. Following is the format of the new binary file.
+------------------------------------------------------------+
| Field | Size | Description |
+------------------------------------------------------------+
| Marker | 4 bytes | "$SAR" |
+------------------------------------------------------------+
| Version | 1 byte | Current version = 1 |
+------------------------------------------------------------+
| SAR table | 2 bytes | Offset of SAR table from start of |
| offset | | the header |
+------------------------------------------------------------+
| WGDS | 2 bytes | Offset of WGDS table from start of |
| offset | | the header |
+------------------------------------------------------------+
| Data | n bytes | Data for the different tables |
+------------------------------------------------------------+
This change supports both the legacy and the new format of SAR file

It doesn't make sense to store the orientation field directly in the
panel information structure, which is supposed to be reuseable between
different boards. The thing that determines orientation is how that
panel is built into the board in question, which only the board itself
can know. The same portrait panel could be rotated left to be used as
landscape in one board and rotated right to be used as landscape in
another. This patch moves the orientation field out of the panel
structure back into the mainboards to reflect this.

In particular:
* elog_fill_timestamp(), elog_update_checksum(), elog_checksum_event()
were moved to commonlib/bsd/elog
* elog_fill_timestamp() receives the time parameters and updates the

Move elog_internal.h to commonlib/bsd/include/bsd/.
And rename it from elog_internal.h to elog.h.
Since this file will be included from util/ it also converts the "uNN"

The two defines that are not used by util/ are moved to
drivers/elog/elog.c, the only file that includes them.
Move also the function elog_verify_header() from drivers/elog/, to
commonlib/bsd/elog.c since this function will be called from util/
as well.
The rationale behind moving elog's defines & structs to
commonlib/bsd/include is to make them available to util/ tools and/or

The Fast Read Dual Output and Fast Read Dual I/O commands are
practically identical, the only difference being how the read address is
transferred (saving a whooping 2 bytes which is totally irrelevant for
the amounts of data coreboot tends to read). We originally implemented
Fast Read Dual Output since it's the older command and some older
Winbond chips only supported that one... but it seems that some older
Macronix parts for whatever reason chose to only support Fast Read Dual
I/O instead. So in order to make this work for as many parts as
possible, I guess we'll have to implement both. (Also, the Macronix
device ID situation is utter madness with different chips with different
capabilities often having the same ID, so we basically have to make a
best-effort guess to strike a trade-off between fast speeds and best
chance at supporting all chips. If this turns out to be a problem later,
we may have to add Kconfig overrides for this or resort to SFDP parsing,
although that would defeat the whole point of trying to be fast.)

This reverts commit ce0e2a014009390c4527e064efb59260ef4d3a3b which was
originally introduced as a workaround for the bug that the Linux kernel
doesn't know what to do with type 16 memory region in the e820 table
where CBMEM resides and disallowed accessing it. After depthcharge was
patched to mark the type 16 region as a normal reserved region, the
Linux kernel now can access the BERT region and print BERT errors. When
SeaBIOS was used as payload it already marked the memory region
correctly, so it already worked in that case.
After commit 8c3a8df1021b8a2789c2a285557401837f9fc2b8 that removed the
usage of the BERT memory region reserved by the FSP driver by the AMD
Picasso and Cezanne SoCs and made them use CBMEM for the BERT region,
no other SoC code uses this functionality. The Intel Alderlake and
Tigerlake SoCs put the BERT region in CBMEM and never used this reserved
memory region and the change for the Intel server CPU to use this was
abandoned and never landed in upstream coreboot. AMD Stoneyridge is the
only other SoC/chipset that selects ACPI_BERT, but since it doesn't
select or use the FSP driver, it also won't be affected by this change.

Since TBT controller can have maximum 2 ports per controller, our
code will loop over DFP structure twice and determine port number.
Retimer driver used to assign port number as below:
1. Check if power GPIO is assigned for particular DFP entry or not
2. If entry is there, assign loop count as port number
Since loop count is 2, retimer will never assign port number = 2
even if it's present. In case of more than 1 controller, port number
assigned will still be 0 or 1 even though actual port index might
be 2 or 3. This will create an issue where even if you do transaction
on device on controller 2 (port index 2 or 3), EC will route it on
port 0 or 1 due to incorrect port index.
Update the driver flow as per below to handle this scenario:
1. Check if power GPIO is assigned for particular DFP entry or not
2. Get USB port number from config since it's stored in usb port
information under devicetree
3. Pass the port number to ACPI SSDT and EC code
Above changes will ensure that we're assigning correct port
number as per calculation and EC will use correct port index.

of memory which is equal to size of VBT (cbmem_add(extended_vbt))
4. Pass physical address pointer to OS via RVDA
We can optimize the above flow to allocate single chunk of memory by
checking VBT size in earlier step. The new optimized flow for opregion
init is as below:
1. Check if VBT size > 6 KiB (this requires extended VBT support)
2. In case of extended VBT requirement, total memory to be allocated
is calculated as sizeof(opregion) + sizeof (extended_vbt)
In case where VBT size is < 6 KiB, total memory requirement would
be equal to sizeof(opregion)
3. Based on above calculation, allocate single chunk of memory based on
total size.
This will also be helpful for the case of virtualization where guest
users don't have access to physical address and when it needs relative
address of VBT compared to absolute address.
In case of opregion 2.1 spec, we need to pass relative address of
VBT from opregion base in RVDA. This optimization will help in meeting
this requirement since relative address of extended VBT is easy to get.
This change will ensure that it meets opregion specification
requirement and will be compatible with future versions as well.

TEST=check the address of extended VBT region and address is coming
correctly.

This adds OEM variables feature under DPTF as per BWG doc #541817. Using
this, platform vendors can expose an array of OEM-specific values as OEM
variables to be used in determining DPTF policy. These are obtained via
the ODVP method, and then simply exposed under sysfs. In addition, these
gets updated when a notification is received or when the DPTF policy is
changed by userspace.

Now that the refactoring is complete, the unions for the table header
are no longer needed. Therefore, drop them.

Introduce the `smbios_full_table_len` function to consolidate table
length calculation. The case where the length of a table equals the
length of the structure happens when a table has no strings.

Factor out some boilerplate code into a helper `smbios_carve_table`
function, which zeroes out the table memory and fills in the header
fields common to all tables.

All SMBIOS `type X` tables start with the same 4-byte header. Add a
struct definition for it, and use it where applicable. The union is
temporary and allows doing the necessary changes in smaller commits.
