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.

Now that CBFS has this functionality built in, we no longer need to
manually code it.
payload_preload used to use the payload_preload_cache region to store
the raw payload contents. This region was placed outside the firmware
reserved region, so it was available for use by the OS. This was
possible because the payload isn't loaded again on S3 resume.
cbfs_preload only uses the cbfs_cache region. This region must be
reserved because it gets used on the S3 resume path. Unfortunately this
means that cbfs_cache must be increased to hold the payload. Cezanne is
the only platform currently using payload_preload, and the size of
cbfs_cache has already been adjusted.
In the future we could look into adding an option to cbfs_preload that
would allow it to use a different memory pool for the cache allocation.

Rename configure_espi to configure_espi_with_mb_hook to clarify that
this function will call into the mb_set_up_early_espi function in the
mainboard-specific code if it exists.

Before this patch the reservation of the MMIO region of the I2C
controllers was done in the LPC controller PCI device despite the I2C
controllers already being devices in the devicetree. This patch
implements this functionality as read_resources function of the I2C
device instead. This will only reserve the memory when the I2C devices
are enabled in devicetree which is a change from the previous behavior.

Since espi_util.c is also built in the case of verstage on PSP, we can
just add it to all stages.

Add support to handle S0ix entry and exit notifications by adding the
corresponding _DSM functions. The function indices are chosen based on
the Modern Standby BIOS Implementation Guide 56358 Rev. 1.04. Inside
the notification functions perform any mainboard specific S0ix entry and
exit actions.
BUG=b:195748540
TEST=Build and boot to OS in Guybrush. Ensure that the notification
functions are invoked on S0ix entry and exit. Perform suspend/resume
cycles for multiple iterations.

switch to higher speeds after assessing the signal integrity. Also

Currently all SPI speed configurations are done through EFS at build
time. There is a need to apply SPI speed overrides at run-time - eg.
based on board version after assessing the signal integrity. This
override configuration can be carried out by PSP verstage and bootblock.
Export the APIs to set and read SPI speeds from both PSP verstage and
bootblock.

eSPI is setup in two different locations in bootblock depending on early
port80 routing configuration. Also eSPI is setup in PSP, if verified
boot starts before bootblock. Consolidate all the scenarios by
initializating eSPI very early in fch_pre_init if verified boot starts
after bootblock and eSPI is enabled.

For 1 bit long bit fields an unsigned type should be used. In this case
uint32_t is used instead of a generic unsigned int for both consistency
reasons with the rest of the file and to clarify that the bits will be
packed into a 32 bit memory location.
TEST=Resulting image of a timeless build for google/guybrush results in
identical binary.
