IFDv1 always has 8 regions, while IFDv2 always has 16 regions.
It's platform specific which regions are used or are reserved.
The 'SPI programming guide' as the name says is a guide only,
not a specification what the hardware actually does.
The best to do is not to rely on the guide, but detect how many
regions are present in the IFD and expose them all.
Very early IFDv2 chipsets, sometimes unofficially referred to as
IFDv1.5 platforms, only have 8 regions. To not corrupt the IFD when
operating on an IFDv1.5 detect how much space is actually present
in the IFD.
Fixes IFD corruption on Wellsburg/Lynxpoint when writing a new
flash layout.

The patch adds Kconfigs to define scaling factor for Efficient and
Performance cores instead of using hard coded values in the soc code.
Also, the patches uses the Kconfigs directly to calculate the core's
nominal performance. So, we don't need to implement soc function
soc_get_scaling_factor() to get the scaling factor data for different
core types. Hence, soc_get_scaling_factor() function is removed.
TEST=Build the code for Gimble and Rex. Also, I have verified that
build system logs error when the Kconfigs are undefined.

When the watchdog timer reaches 0, the timer value won't reset to the
default value unless there is an external reset or a kick. It will
result in the watchdog failing to trigger the reset signal.
We kick the watchdog to reset the timer to the default value. Also,
because WDT hardware needs about 94us to synchronize the registers,
add a 100us delay before triggering the reset signal.

When AP boots up after Cr50 firmware update and reboot, AP finds
that Cr50 reset is required for Cr50 to pick the new firmware so
it trigger Cr50 reset and power off the system, AP expects system
will power on automatically after Cr50 reset. However this is not
the case for Chromebox, Chromebox EC set AP_IDLE flag when system
is shutting down, when AP_IDLE flag is set in EC, the system stays
at S5/G3 and wait for power button presssend. It cause an issue in
factory that the operator needs to press power button to power on
the DUT after Cr50 firmware update.

get_cpu_index() helper function returns cpu's index based on it's APIC
id position from the ascending order list of cpus' APIC IDs.
In order to calculate the cpu's index, the helper function needs to
traverse through each cpu node to find their APIC IDs. So, the function
traverse the CPU node list from the cpu whose APIC ID is 0 assuming it
is the first cpu node in the list. This logic works fine where BSP's
APIC ID is 0. But, starting from MTL, APIC ID for BSP need not be 0 as
APIC ID numbering first get assigned for CPU Die Efficient cores, then
Performance cores.
Please refer section# 6.1 of doc#643504 for more details on APIC IDs.
Considering the APIC Id allotment for MTL cores, as existing code
traversing begins from the cpu that has APIC Id#0 which may not be the
first cpu node in the list so index calculation results in wrong value.
The patch addresses above described issue by traversing all the CPU
nodes to calculate the cpu index. Also, prevents inconsistent report
of /sys/devices/system/cpu/cpu*/cpufreq/* and
/sys/devices/system/cpu/cpuXX/acpi_cppc on each reboot.
TEST=Verified that the get_cpu_index helper function returns the correct

helpful for SoC users to perform TXT related operations
(like Disabling TXT) even without selecting INTEL_TXT config.
At present, those helper functions are only available upon selecting
INTEL_TXT which is not getting enabled for most of the SoC platform in
the scope of the Chromebooks.
TEST=Able to access functions from txtlib.c even without selecting
INTEL_TXT config.

Sometimes, server platforms may have more than one socket on server
board. However, there's no field to store information about which
socket the DIMM comes from in dimm_info structure.
This patch adds soc_num field in dimm_info structure to store socket
ID of the DIMM.

If cbmem_top is not 1M aligned there will be a hole between DPR base
and cbmem_top that the allocator will consider as unassigned memory.
Resources could incorrectly be assigned to that region and the final
MTRR solution will also try to skip that hole, therefore using a lot
more variable MTRRs than needed.
TESTED on Archer City 2S system: Uses 1 variable MTRR in the final
setup instead of 7.

Software Connection Manager doesn't work with Linux 5.13 or later,
resulting in TBT ports timing out. Not advertising this results
in Firmware Connection Manager being used and TBT works
correctly.
Add Kconfig options to chose between SCM (Software Connection
Manager) and FCM (Firmware Connection Manager). FCM is primary, as
it's more compatible save for ChromeOS devices as ChromeOS uses
SCM.

Because skyrim is loading ramstage from SPI with the DMA engine, the
size of the compressed image is less important to load speed than
decompression time.
Because the LZ4 decompression is so much faster than LZMA, compressing
with LZ4 saves us roughly 30ms in boot time.
For size, we're spending roughly 57KiB:
fallback/ramstage 0x9b00 stage 130864 LZMA (305316 decompressed)
fallback/ramstage 0x9b00 stage 189126 LZ4 (305316 decompressed)
Right now we have 2MiB empty space in Skyrim's RO before this change,
and roughly 550KiB empty space in RW, so there aren't currently any
size worries.
Just for fun, I also tested uncompressed ramstage, and it was still
18ms faster than LZMA, but that makes it roughly 12ms slower than LZ4.

Previously, LZMA was included in romstage because it was almost always
needed to decompress ramstage. When compressing ramstage with LZ4, but
using LZMA compression for FSP-M, we still need the LZMA decompression
to be present, so update when the Makefile includes the LZMA decoder.

When ramstage is loaded asynchronously, as on the skyrim boards, the
faster decompression of LZ4 allows for faster boot times than the
tighter compression of LZMA.
To make this change, the name of the existing ramstage_compression
