VMX is enabled through a bit in the IA32_FEATURE_CONTROL MSR, which can
be locked. The MSR remains locked after a non-power cycle reset, though.
If the MSR is locked, coreboot bails out and leaves VMX in the state it
was found. Because of this, changes to the VMX enable option in the BMC
only take effect after the system is power cycled.
This behaviour is highly undesirable because users are likely not aware
that a power cycle is required for changes to VMX state to take effect.
So, if VMX is supported, the IA32_FEATURE_CONTROL MSR is locked and the
current VMX state does not match the requested state, then issue a full
reset. This will power cycle the system and unlock the MSR, so that the
desired VMX state can be programmed into the MSR. This is checked early
to avoid needlessly doing time-consuming operations (running FSP) twice
if we know we will need to power cycle the system anyway.
Note that a user may change the VMX setting after the newly-added check
but before the setting is read in ramstage to program the MSR, but this
is a non-issue as firmware settings need a reset to take effect anyway.
TEST: Toggle VMX setting in BMC and reboot without power cycle, observe
coreboot automatically issues a power cycle reset because the MSR
is locked and the VMX state differs. Verify that the system boots
properly with VMX in the correct state after having power cycled.

Intel Client PCIe* controller expects each device should drive the

not support SRCCLKREQ#, then during RTD3 exit link would not be
established. Because controller samples the SRCCLKREQ# before
detecting the device and break L1 as the system might enter L1SS as
controller detects SRCCLKREQ# as de-asserted.
As a workaround the Pins must not be configured in Native Mode (CLKREQ
native function). Therefore here they are not configured at all.
source: 689882 (intel document ID)
So apparently hardware doesn't sample SRCCLKREQ Pin if it's not
configured as such.
That workaround suggestion however also brought a patch to FSP, which
in turn causes the same bug (even if SRCLKREQ are not configured).
Usually in order to make use of root port power saving features (e.g.
clock gating), the Root port must either be disabled or a CLKREQ Pin
must be configured. The patch however removed that check before
enabling power management for the rootport.
Workaround (until FSP is fixed):
pretend to FSP that the rootports have a CLKREQ Pin attached, by
supplying them in the FSP UPDs. That will cause FSP to configure the
CLKREQ Pin and enable power management for said rootport, but it will
not crash on L1 entry/exit. That has been done on the Atlas board
(as workaround) for a short period of time (before applying FSP Fix)
like this:
// RP 5 (the rootport you want to fix)
- memupd->FspmConfig.PcieClkSrcUsage[2] = 4;
// e.g. choose a clkreq pin that is not routed out
- memupd->FspmConfig.PcieClkSrcClkReq[2] = 0;
Furthermore disable CpuPcieRpClockReqMsgEnable FSP-M options to prevent
the same issue, but for CPU root ports. If not done the following will

Configure the Intel iGPU as primary video adapter if enabled according
to EEPROM settings. The default is to use the ASPEED BMC as primary
video adapter, which only has a VGA output and the remote KVM output.
For now, use the FSP GOP driver to light up the iGPU. There are several
issues with libgfxinit on the Hermes, probably due to the unusual setup
of the iGPU's display outputs. They are routed to a mezzanine connector
for a piggy-back sub-board, of which there are two models. The Poseidon
piggy-back has two DisplayPort outputs and an HDMI output coming from a
MegaChips LSPCON. The Avalanche piggy-back routes all three DisplayPort
outputs from the iGPU into a FPGA, which acts as a DisplayPort sink.
Note that the FSP GOP only initializes at most 2 iGPU display outputs.
However, all three outputs function properly once OS (Windows, Linux)
graphics drivers take over.
Additionally, update the config file that Prodrive uses to build
coreboot images so that the iGPU can be used as primary.
TEST=Verify that the iGPU's outputs work properly in pre-OS, Windows and

Strings in C are highly cursed. Use `snprintf()` to minimize the
potential of running into undefined behavior in the future.

The `eeprom_read_serial()` function could return a non-NULL terminated
string if the serial in EEPROM has `HERMES_SN_PN_LENGTH` (32) non-NULL
characters. Make this impossible by adding an additional character for
a NULL byte in the static buffer, which always gets set to 0 (NULL).

First of all, make sure that `get_board_settings()` never returns NULL.
If there's a problem, return predefined values for board settings.
If the board settings definition differs between coreboot and the BMC,
the CRC will not match. Allow coreboot to use the BMC settings provided
by older BMC firmware revisions which have less settings, if the CRC of
the first N bytes matches the expected CRC.
TEST=Boot coreboot master with BMC FW R04.05, observe board settings
being honored even though coreboot's definition has an extra option.

Adjust the EEPROM layout to account for two new fields: board part
number and product part number. In addition, put them in a Type 11
SMBIOS table (OEM Strings). Also, rename a macro to better reflect
its purpose.

Add the `eeprom_read_serial()` function to read serials from the EEPROM.
Note that there's only one buffer now: this means only one serial can be
accessed at the same time, and the buffer needs to be cleared so that it
does not contain old data from other serials. Given that the serials are
copied one at a time into SMBIOS tables, having one shared buffer is not
a problem.

The PCH's SGPIO pads are connected to a buffer chip that is powered from
the always-on +3V3_AUX rail. For some cursed reason, when the SGPIO pads
stay configured as SGPIO when a Poseidon system shuts down, voltage from
the +3V3_AUX-powered buffer chip will leak into the +5V rail through the
SATA backplane. Just pulling the SGPIO pads low before the system powers
off stops the +5V rail from being cross-powered.
This issue has only been observed in S5, but it's very likely other
sleep states are affected as well. Thus, always pull the SGPIO pins
low before entering ACPI S3 or deeper because the power supply will
turn off in these states as well.
TEST=Obtain a Poseidon system, verify that the +5V rail is cross-powered
after going to S5. We measured 0.17V on our system, but voltages as
high as 0.6V were measured on other systems. Verify that unplugging
the SGPIO cable going to the SATA backplane results in the +5V rail
voltage dropping to 0V, which indicates that the voltage leakage is
exclusively coming from the SGPIO and SATA backplane. Finally, make
sure that the +5V rail voltage drops to 0V after going into ACPI S5
with this patch applied and the SGPIO cable connected.

It turns out that one can use Kconfig options to specify values for
devicetree options, as long as the resulting expression is a compile
time constant. Use this to configure SaGv for Atlas: enable it by
default, but allow SaGv to be disabled manually for convenience when
testing. Enabling SaGv makes MRC train the RAM multiple times, which
takes a significant amount of time.
For further info on SAGV on ADL, please refer to Intel Doc 655258
(Alder Lake Datasheet) section 5.1.3.2.
