a585358f9b soc/intel/skylake: Enable PARALLEL_MP_AP_WORK
With change a4b11e5c90 (soc/intel/skylake: Perform CPU MP Init
before FSP-S Init) to perform CPU MP init before FSP-S init, MTRR
programming was moved to be performed after CPU init is done. However,
in order to allow callbacks after MP init, PARALLEL_MP_AP_WORK needs
to be enabled. Since this option was not selected, MTRR programming
always failed in ramstage for Skylake / Kaby Lake mainboards.

BUG=b:36656098
TEST=Verified 2500+ cycles of suspend resume on poppy.

79f0741f81 soc/intel/skylake: use postcar stage for fsp 2.0
Utilize the postcar stage for tearing down CAR and initializing
the MTRRs once ram is up. This flow is consistent with apollolake
and allows CAR_GLOBAL variables to be directly accessed and no
need for migrating CAR_GLOBAL variables as romstage doesn't
run with and without CAR being available.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

320edbe2ba vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by default
The virtualized developer switch was invented five years ago and has
been used on every vboot system ever since. We shouldn't need to specify
it again and again for every new board. This patch flips the Kconfig
logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with
CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to
set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the
latter for Lumpy which seems to have been omitted incorrectly, and hide
it from menuconfig since it's a hardware parameter that shouldn't be
configurable.)

Since almost all our developer switches are virtual, it doesn't make
sense for every board to pass a non-existent or non-functional developer
mode switch in the coreboot tables, so let's get rid of that. It's also
dangerously confusing for many boards to define a get_developer_mode()
function that reads an actual pin (often from a debug header) which will
not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set.
Therefore, this patch removes all those non-functional instances of that
function. In the future, either the board has a physical dev switch and
must define it, or it doesn't and must not.

In a similar sense (and since I'm touching so many board configs
anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC.
Instead, it should just be assumed by default whenever a Chrome EC is
present in the system. This way, it can also still be overridden by
menuconfig.

2864f85725 intel/skylake: Disable FADT.8042 if NO_FADT_8042 is set
Kernel relies on FADT 8042 flag to enable/disable
8042 interface. If FADT reports 8042 capability and
8042 (/PS2) capability is actually disabled by coreboot,
kernel would assume the presence of 8042 based on the
FADT flag. This results in undesired system power off when
kernel tries to access the 8042 memory region. To address
this, CONFIG_NO_FADT_8042 was added to selectively
disable 8042 on FADT.

a6914d2343 soc/intel/skylake: align chromium Chrome OS config
The chromium tree is currently using a different config for
Chrome OS than what is being built in coreboot.org. Align those
settings to reflect how skylake Chrome OS boards are actually
shipped to provide proper parity between coreboot.org and chromium.

e4cc8cd00b soc/intel/skylake: use SPI flash boot_device_rw() for ealy stages
If the boot device is SPI flash use the common one in the
early stages. While tweaking the config don't auto select
SPI_FLASH as that is handled automatically by the rest of the
build system.

e8e118dd32 Kconfig: introduce writable boot device notion
Indicate to the build system that a platform provides support
for a writable boot device. The following will provide the
necessary support:

COMMON_CBFS_SPI_WRAPPER users
soc/intel/apollolake
soc/intel/baytrail
soc/intel/braswell
soc/intel/broadwell
soc/intel/skylake

The SPI_FLASH option is auto-selected if the platform provides
write supoprt for the boot device and SPI flash is the boot
device.

Other platforms may provide similar support, but they do that
in a device specific manner such as selecting SPI_FLASH
explicitly. This provides clearance against build failures
where chipsets don't provide SPI API implementations even
though the platform may use a SPI flash to boot.

3ad63565a5 soc/intel/skylake: Correct Cache as ram size
DCACHE_RAM_SIZE_TOTAL is set to 0x40000 and is being used to
set up CAR. Whereas DCACHE_RAM_SIZE which is set to 0x10000
is used to calculate the _car_region_end in car.ld. If the FSP CAR
requirement is greater than or even close to DCACHE_RAM_SIZE then,
the CAR region for FSP will be determined to be below the overall
CAR region boundary i.e, out of CAR memory range.

This is working with FSP 1.1 because we provide the FspCarSize
and FspCarBase explicitly in a UPD. Hence, FSP is still able to
use the upper region of CAR memory for its purpose.
However, it will be a problem in case of FSP2.0 where FSP usable CAR
is calculated using _car_region_end.

So, Remove the the use of DCACHE_RAM_SIZE_TOTAL and set
DCACHE_RAM_SIZE to correct value i.e, 0x40000(256KB)

4001f244ad skylake: Support common LPSS I2C driver
Support the common Intel LPSS I2C driver for the 6 I2C bus controllers
that are present on the Skylake-LP PCH with a 120 mHz clock.  The
required lpss_i2c_base_address() method is implemented separately for
verstage/romstage and ramstage environments.

This provides methods to convert to and from "struct device" and the
I2C controller bus number for that device.  These are used to provide
support for the "I2C Bus Operations" that are present in the coreboot
devicetree.

To support the I2C controller before ramstage an early init function
is provided to do minimal initializaiton of the PCI device and assign
a temporary base address for use before memory.  The final base
address is assigned during device enumeration and used during ramstage.

Because it is usually not necessary to enable I2C controllers before
ramstage a config register for the devicetree is provided to perform
early initialization of this controller.  In addition the bus speed
can be set in the devicetree and that speed will be applied when the
device is initialized.  If not provided the default speed is set to
I2C_SPEED_FAST.

This was tested with the google/chell mainboard by reading and writing
from the trackpad and codec devices during both verstage and ramstage.
