The corresponding bit is marked as reserved in the following versions of
the documentation for all SoCs using this code:
Mullins: BKDG #52740 Rev 3.05
Stoneyridge: BKDG #55072 Rev 3.04
Raven1, Picasso: PPR #55570 Rev 3.16 & 3.18
Raven2: PPR #55772 Rev 3.08
Cezanne: PPR #56569 Rev 3.03
The old Rev 3.14 of the Picasso PPR #55570 had the bit 19 defined as
PullUpSel, but this is no longer the case in newer versions. It is
unclear if this got de-featured or if it was never present in the
silicon. To be consistent with the current documentation, drop this
define.
This patch also change the definition of GPIO_PULL_MASK to only cover
the bits used for the feature. The Cezanne PPR #56569 Rev 3.03 states a
default value of 0 for this bit after reset, so the resulting values in
the register aren't expected change. The other PPRs/BKDGs don't specify
a reset value for this bit, but it's likely safe to assume that all SoCs
that use the new GPIO interface use the same GPIO building block.

Disable PSE loading by default. If left enabled (current default),
the EHL coreboot will end up in endless restart loop, due to FSP
unable to locate PSE FW image and trigger global reset.
However disabling this flag (PchPseEnable) will cause the coreboot
to trigger a single reset due to CSE signal (HECI: CSE does not
meet required prerequisites). The reason behind this is that FSP
need to perform static disabling (power gate) to fully shut down
PSE HW, and to do this will need to global reset entire system
including CSE. Then PMC will power gate PSE from the start.
To avoid this behavior, the best way to disable PSE is to disable
via IFWI FIT softstrap (For specific detail can refer to Intel EHL
coreboot MR2 release notes). With this, PMC will power gate PSE
from the first cold boot and system will boot happily without
single reset behavior.

The Prodrive Hermes mainboard has four i211 Ethernet NICs and an i210
Ethernet NIC, but their numbering isn't consistent with the PCIe root
port function numbers. With only a M.2 SSD plugged in, Linux uses the
following names:
PHY 0 ---> enp6s0
PHY 1 ---> enp4s0
PHY 2 ---> enp3s0
PHY 3 ---> enp1s0
PHY 4 ---> enp2s0
These names change after adding or removing PCIe devices in slots
connected to root ports that get enumerated before the NICs' root
ports, because the assignment of secondary bus numbers depends on
the enumeration order. Because of this, the "predictable" network
interface names are not at all predictable, which is awful.
To avoid this, describe the NICs using SMBIOS Type41 entries with the
correct instance numbers. With this patch, Linux uses these names:
PHY 0 ---> eno0
PHY 1 ---> eno1
PHY 2 ---> eno2
PHY 3 ---> eno3
PHY 4 ---> eno4
No matter what PCIe devices are present, these names don't change.

This workaround is not triggered in QEMU, because
BOOT_DEVICE_MEMORY_MAPPED is only selected for SPI boot devices. This
results in confusing (to the VMM developer) writes to read-only
memory.
As far as I can tell, this issue is weird but harmless, because the
code does memcpy to ROM with source == destination. The concensus in
the mailing list thread [1] was that it's worthwhile to be fixed
