VPD reference: https://chromium.googlesource.com/chromiumos/platform/vpd/+/master/README.md
Copy ChromeOS VPD driver to add support for VPD without CROMEOS.
Possible use case:
* Storing calibration data
* Storing MAC address
* Storing serial
* Storing boot options
+ Now it's possible to define the VPD space by choosing
one of the following enums: VPD_ANY, VPD_RW, VPD_RO.
+ CHROMEOS selects now VPD as part of it.
+ VPD is implemented as driver.

Add functions to build a Boot Error Record Table region based on
settings found in the MCA registers.
Two entries are reported for each error due to the nature of the ACPI
driver. The first is a Generic Processor Error, which the OS recognizes
and parses. Generic errors cannot convey much error description or
processor context. Therefore an IA32/X64 Processor Error is also added,
which allows reporting the values found in the MCA MSR registers.
Follow-on work could decode the MC errors more precisely, and better
completing the Generic Error and the Check structure. The current
level of support is sufficient to identify a (i.e., human readable)
problem in dmesg, and provides adequate context information for
analysis.

Add code for generating the region pointed to in an ACPI Boot Error
Record Table.
The BERT region must be reported as Reserved to the OSPM, so this
code calls out to a system-specific region locator. cbmem is
reported as type 16 and is not usable for the BERT region.
Events reported via BERT are Generic Error Data, and are constructed
as follows (see ACPI and UEFI specs for reference):
* Each event begins with a Generic Error Status Block, which may
contain zero or more Generic Data Entries
* Each Generic Data Entry is identifiable by its Section Type field,
and the data structures associated are also in the UEFI spec.
* The GUIDs are listed in the Section Type field of the CPER
Section Descriptor structure. BERT doesn't use this structure
but simply uses its GUIDs.
* Data structures used in the Generic Data Entry are named as
Error Sections in the UEFI spec.
* Some sections may optionally include a variable number of
additional structures, e.g. an IA32/X64 processor error
can report error information as well as machine contexts.
It is worth noting that the Linux kernel (as of v4.4) does not attempt
to parse IA32/X64 sections, and opts to hexdump them instead.

Nautilus-Wifi was FCS with Celeron AP first and also its PCB/BOM was

reflect the potential noise hidden inside the board.

potential noise coupling to VCC_GT/SA, and we verified this change

BOOTBLOCK/ROMSTAGE run in CAR/scratchpad. When RAMSTAGE begins
execution will enable cache, then CAR will disappear. So the
Stack will be separated.

Enable dGPU power handling on Lenovo ThinkPad T430, T530 via PMH7
register 0x50.
Although there's no Thinker-1 chip on these models according to
schematics, dGPU power control via PMH7 works the same as on T420/T520,
so they can be considered Thinker-1-compatible.
It can be tested from linux userspace using util/pmh7tool.
To turn dGPU power off:
pmh7tool -c 0x50 7
pmh7tool -c 0x50 3
To turn it on:
pmh7tool -s 0x50 3
pmh7tool -s 0x50 7
To check whether it is on (bash):
reg=0x$(pmh7tool -r 0x50)
echo "$(( (( reg & 0x08 )) >> 3 ))"
or just `pmh7tool -b 0x50 3` with
