When using the default initial core display clock frequency, Metaknight
has a rare stability issue where the startup of Chrome OS in secure mode
may hang. Slowing the initial core display clock frequency down to
172.8 MHz as per Intel recommendation avoids this problem.
The CdClock=0xff is set in dedede baseboard,and we overwrite it as 0x0
(172.8 MHz) for metaknight.
BUG=None
BRANCH=dedede
TEST=Build firmware and verify on fail DUTs.

Commit b67c5ed [3rdparty/fsp: Update submodule pointer to newest master]
updated the FSP binaries/headers for Comet Lake, which included a change
moving PcieRpHotPlug from FSP-S to FSP-M. Unfortunately the existing
UDP in FSP-S was left in and deprecated, which allowed the change to go
unnoticed until it was discovered that hotplug wasn't working.
Since other related platforms (WHL, CFL) share the SoC code but use
different FSP packages, add the setting of the PcieRpHotPlug UPD to
romstage/FSP-M and guard it with '#if CONFIG(SOC_INTEL_COMETLAKE)'.

This patch extends `struct pad_config` to add new variable for gpio
lock action.
Additionally, it creates new GPIO PAD configuration macros that perform
GPIO pad configuration and pad lock configuration as well.
List of new macros are:
1. PAD_CFG_NF_LOCK
2. PAD_CFG_GPO_LOCK
3. PAD_CFG_GPI_LOCK
4. PAD_CFG_GPI_TRIG_OWN_LOCK
5. PAD_CFG_GPI_GPIO_DRIVER_LOCK
6. PAD_CFG_GPI_INT_LOCK
7. PAD_CFG_GPI_APIC_LOCK
8. PAD_CFG_GPI_IRQ_WAKE_LOCK
Mainboard users can use the above macros to lock the PAD after
configuration.
So far on IA chipset, the default GPIO pad lock configuration reset
type is POWERGOOD hence, it's recommended as per GPIO BWG (doc: 630603)
to configure the GPP PAD reset type the same as lock configuration
reset type to avoid GPP reset value misconfiguration issue.

The TCO timer is the default watchdog of an x86 host and can reset the
system once it has expired for the second time. There are applications
where this reset is not acceptable while the TCO is used. In these
applications the TCO expire event generates an interrupt and software
takes care. There is a bit in the TCO1_CNT register on Elkhart Lake to
prevent this reset on expiration (called NO_REBOOT, see doc #636722 ).
This bit can either be strapped on hardware or set in this register to
avoid the reset on expiration. While the hardware strap cannot be
overridden in software, the pure software solution is more flexible.
Unfortunately, the location for this bit differs among the different
platforms. This is why it has to be handled on soc level rather than on
TCO common code level.
This commit adds a Kconfig option where NO_REBOOT can be enabled. This
makes it easy to reach this feature over to the mainboard where it can
be selected if needed.

Chromebooks normally run with non-serial enabled firmware because
writing to the UART console is very slow. This unfortunately makes
debugging boot errors more difficult. We tend to rely on port 80s and/or
the vboot recovery code.
When CONSOLE_CBMEM_DUMP_TO_UART is selected it will dump the entire
cbmem console to the UART whenever `vboot_reboot()` is called. We don't
incur any boot time penalty in the happy path, but still retain the
ability to access the logs when an error occurs.
The previous implementation was using a hard coded UART index and
`get_uart_baudrate` was always returning 0 since `CONFIG_TTYS0_BAUD`
wasn't defined. This change makes it so the UART console properties are
available when CONSOLE_CBMEM_DUMP_TO_UART is set. This results in the
following .config diff:
+CONFIG_UART_FOR_CONSOLE=0
+CONFIG_TTYS0_BASE=0x3f8
+CONFIG_TTYS0_LCS=3
+CONFIG_CONSOLE_SERIAL_115200=y
+CONFIG_TTYS0_BAUD=115200
This functionality is especially helpful on Guybrush. PSP Verstage is
run on S0i3 resume. Today, if there is an error, the cbmem console is
lost since it lives in the PSP SRAM.

Enable PSE GBE with following changes:
1. Configure PCH GBE related FSP UPD flags
2. Add PSE GBE ACPI devices
3. Refactor PCH GBE FSP-S code and merge it together
with PSE GBE code

The Intel® Programmable Services Engine (Intel® PSE) is a
dedicated offload engine for IoT functions powered by an ARM
Cortex-M7 microcontroller. It provides independent, low-DMIPS
computing and low-speed I/Os for IoT applications, plus
dedicated services for real-time computing and time-sensitive
synchronization.
The PSE hosts new functions, including remote out-of-band
device management, network proxy, embedded controller lite
and sensor hub.
This CL enables the user to provide the base address of the
PSE FW blob which will then be loaded by the FSP-S onto the
ARM controller. PSE FW will do the initialization work of
PSE controller and its peripherals. The loading of PSE FW
should have negligible impact on boot time unless PSE
controller could not locate the PSE FW and FSP will attempt to
redo PSE FW loading and wait for PSE handshake until it times
out. Once PSE controller locate the PSE FW, it will do
initialization concurrently by itself with coreboot booting.
It also adds PSE related FSP-S UPD settings which enable the
setup of peripheral ownership (assigned to the PSE or x86
subsystem) and interrupts. These assignments need to take
place at a given point in the boot process and cannot be
changed later.
To verify if PSE FW is loaded properly, the user could enable
PchPseShellEnabled flag and the log will be printed at PSE UART
2.

and #614110 (for PSE EDS).
