Is there maybe a more common-code place where we could add it?

Hello Angel Pons, Arthur Heymans, Benjamin Doron, Maximilian Brune, Michał Kopeć, Nico Huber, Paul Menzel, Werner Zeh, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/68944?usp=email
to look at the new patch set (#18).
The following approvals got outdated and were removed:
Code-Review+1 by Nico Huber
Change subject: soc/intel/common/block/oc_wdt: Add OC watchdog common block
......................................................................
soc/intel/common/block/oc_wdt: Add OC watchdog common block
Add new block for handling overcloking watchdog. The watchdog is
present since Skylake or maybe even earlier so it is safe to use with
most of the microarchitectures utilizing intelblocks.
The patch adds the common block for initializing and feeding the
watchdog. Timeout is defined statically in Kconfig and should be set
high enough by the board or SoC Kconfig to let the board boot with
full memory training and avoid reset loops. Full training of 128GB
DDR5 DIMM memory on AlderLake takes about 5 minutes. Newer SoCs
with newer memory technologies and higher RAM capacity may take more.
THe default has been set to 10 minutes.
The patch also adds support for feeding watchdog in driverless mode,
i.e. it utilizies periodic SMI to reload the timeout value and restart
the watchdog timer. This is optional and selectable by Kconfig option
as well. If the option is not enabled, payload and/or software must
ensure to keep feeding the watchdog, otherwise the platform will
reset.
TEST=Enable watchdog on MSI PRO Z690-A and see the platform resets
after some time. Enable the watchdog in driverless mode and see the
platform no longer resets and periodic SMI keeps feeding the watchdog.

PS16, Line 169: CONFIG_SOC_INTEL_COMMON_OC_WDT_TIMEOUT_SECONDS
> Ping, Subrata
Patch CB:68944 set high-enough default and does not allow to set the timeout by user in menuconfig anymore (instead SOCs may ovverride the default in their own Kconfig).

May be best to get the other one in first.

Do we want to go along with this instead of the warning override?
Then we should find somebody to test this, I guess?

PS7, Line 7: to add support
If you'd drop `to add support `, it would fit the line without
losing valuable information.
https://review.coreboot.org/c/coreboot/+/76159/comment/8e4decf0_c8c05f29 :
PS7, Line 24: or changing display resolutions with the i2c driver attached.
What happens when the touchpad is used while an external
display is attached/probed?
I would further test how DP cascades behave, e.g. daisy-
chained displays, multi-port docking hubs...
File src/mainboard/google/link/acpi/mainboard.asl:
https://review.coreboot.org/c/coreboot/+/76159/comment/227948fc_495b0b8b :
PS7, Line 49: ){
Missing space before `{`. Same below.
https://review.coreboot.org/c/coreboot/+/76159/comment/c8a838eb_0b68f281 :
PS7, Line 50: LINK
Can't find LINK here: https://uefi.org/acpi_id_list
If it's not going to be registered, we should find a propper way to identify
a custom device. If necessary at all, it seems possible that the Atmel IDs
would already suffice? Could you link to the code of the Windows driver?
https://review.coreboot.org/c/coreboot/+/76159/comment/42b3b2b5_9238e17f :
PS7, Line 51: Method (_STA, 0, NotSerialized) // _STA: Status
: {
: Return (0x0F)
: }
This seems superfluous, 0xf should be the default w/o _STA. Same below.
https://review.coreboot.org/c/coreboot/+/76159/comment/a4b0800a_a5646730 :
PS7, Line 56: MMIO
I don't see this being used, I guess that would be the Windows driver?
Should this be a _DSM?
https://review.coreboot.org/c/coreboot/+/76159/comment/f39d28cb_7da1d18c :
PS7, Line 62: VGA
Doesn't really matter, but I find VGA a bit confusing. What does it mean
in this context?
https://review.coreboot.org/c/coreboot/+/76159/comment/a594bcbd_906e2a9d :
PS7, Line 82: ISTP
Where is this used? For the OS, ATML0000 already identifies as touchpad.
