Add the basics for building as a ChromeOS device. ChromeOS
and ChromeEC are dependent on each other, so bring them in
together. The EC is a Nuvoton and you can find additional
details in the Chromium EC repo.
Add the Google HWID "Kahlee TEST 6421".
The chromeos.fmd for Kahlee takes advantage of the AGESA
located outside cbfs and includes typical RW, VPD, and
MRC areas.
There are some updates required to depthcharge, vboot, GPIOs,
and the ChromeEC before we have a complete-ish system.

Remove the unused support code from the old multi-device hudson
SD controller. The binaryPI blob contains the correct steps
for setting up SD and the public BKDG doesn't completely document
the controller.
The sd.c file was using device IDs not associated with the Stoney
Ridge APU. The hudson_enable() code removed was also looking for
incorrect device IDs and the PM_MANUAL_RESET register doesn't
behave as the source indicates.
The SD default settings may be overridden. Future improvements
may include a few Kconfig options and a weak call to the mainboard
for overriding additional defaults.

Add dedicated CAR setup and teardown functions and Kconfig
options to force their inclusion into the build. The .S files
are mostly duplicated code from the old cache_as_ram.inc file.
The .S files use global proc names in anticipation for use with
the Kconfig symbols C_ENVIRONMENT_BOOTBLOCK and POSTCAR_STAGE.
Move the mainboard romstage functionality into the soc directory
and change the function name to be compatible with the call
from assembly_entry.S. Drop the BIST check like other devices.
Move InitReset and InitEarly to bootblock. These AGESA entry
points set some default settings, and release/recapture the
AP cores. There are currently some early dependencies on
InitReset. Future work should include:
* Pull the necessary functionality from InitReset into bootblock
* Move InitReset and InitEarly to car_stage_entry() and out of
bootblock
- Add a mechanism for the BSP to give the APs an address
to call and skip most of bootblock and verstage (when
available) (1)
- Reunify BiosCallOuts.c and OemCustomize.c
(1) During the InitReset call, the BSP enables the APs by setting
core enable bits in F18F0x1DC and APs begin fetching/executing
from the reset vector. The BSP waits for all APs to also
reach InitReset, where they enter an endless loop. The BSP
sends a command to them to execute a HLT instruction and the
BSP eventually returns from InitReset. The goal would be to
preserve this process but prevent APs from rerunning early
code.

But, FSP was locking the SPI by setting FLOCKDN Bit during Notify

As solution, FSP introduced a new UPD SpiFlashCfgLockDown to skip

Use 16bit write to avoid touching the upper two bytes that may cause
write cycle to fail in case a prior transaction has not completed.
This function sets the WRSDIS(Bit 11) and FLOCKDN (Bit 15) of the
SPIBAR + BIOS_HSFSTS_CTL. While WRSDIS is lockable with FLOCKDN,
writing both in the same cycle is guaranteed to work by design.
Avoid read->modify->write operation not to clear the RW1C bits
unintentionally.
