Hello build bot (Jenkins), Jason Glenesk, Marshall Dawson, Felix Held,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/42685
to look at the new patch set (#9).

soc/amd/common: Drop ACPIMMIO bank for SMBus device PCI config
TBD: Actually used for picasso UART. But can it be changed
to PCI config write? Looks like PSP-verstage currently has
no mapping of this bank. Would be nice if the first code
we execute had control over the UART configuration...

sb,soc/intel: Add wake source fields in GNVS
For the moment, these are most not used but become a necessity
for a unified <soc/nvs.h> approach.
They would be required for the implementation of _SWS method
for OSPM to determine the reason for system waking up. The related
hardware registers are present with these platforms.
It's expected that ACPI power-management related GNVS entries are
grouped together to form a single struct in later works.

Change subject: soc/intel/alderlake: Add support for external clock buffer
......................................................................
Patch Set 1:
(3 comments)
Commit Message:
https://review.coreboot.org/c/coreboot/+/50162/comment/6a1016f8_a802a8e2
PS1, Line 9: 3 CLKSRC using external clock buffer.
: CLKSRC 6 provides feed clock to discrete buffer for further
: distribution to platform.
This is mainboard specific design and nothing to do with what SoC supports.
From SoC standpoint, it supports 7 CLKSRC signals. How those signals are routed on the board is mainboard design.
File src/soc/intel/alderlake/Kconfig:
https://review.coreboot.org/c/coreboot/+/50162/comment/87456af5_0dddfb07
PS1, Line 152: GEN3_EXTERNAL_CLOCK_BUFFER
I don't understand why this is a SoC config. It is a mainboard-specific design.
File src/soc/intel/alderlake/romstage/fsp_params.c:
https://review.coreboot.org/c/coreboot/+/50162/comment/5b835319_54437f31
PS1, Line 156: m_cfg->PcieClkSrcUsage[i] = 0;
> Did you send me the schematics?
Subrata, I do not understand what this change is trying to achieve.
There are 7 CLKSRCs on ADL-P. Thus, FSP UPDs need to know how each of these CLKSRCs are routed -- RP, Free running, LAN, etc.
Beyond that, a mainboard might choose to distribute any clock source in any way it wants. But, FSP doesn't really care about that because there is nothing in the SoC that needs to be configured for the additional clock sources that are generated by the mainboard.
So, why is this code setting PcieClkSrcUsage for something that the FSP doesn't care about?
