561bebfbaa drivers/intel/gma/vbt: Add Kconfig symbol for SSC ref
The selection of the SSC reference frequency for LVDS was based on a
completely unrelated clock.

The `ssc_freq` flag should be set when the SSC reference runs at a
different frequency than the general display reference clock (DREF).
For most platforms, there is no choice, i.e. for i945 and gm45 the SSC
reference always differs from the display reference clock (i945: 66Mhz
SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and
newer, it's the same frequency for SSC/non-SSC (120MHz).  The only,
currently supported platform with a choice seems to be Pineview, where
the alternative is 100MHz vs. the default 96MHz.

71d830fddc i2c/generic: Allow GPIOs to be put in _CRS and PowerResource in ACPI
Linux kernel expects that power management with ACPI should always be
handled using PowerResource. However, some kernel drivers (e.g. ELAN
touchscreen) check to see if reset gpio is passed in by the BIOS to
decide whether the device loses power in suspend. Thus, until the kernel
has a better way for drivers to query if device lost power in suspend,
we need to allow passing in of GPIOs via _CRS as well as exporting
PowerResource to control power to the device.

Update mainboards to export reset GPIO as well as PowerResource for
ELAN touchscreen device.

d8e34b2c44 driver/intel/fsp1_1: Fix boot failure for non-verstage case
Currently car_stage_entry is defined only in romstage_after_verstage and
as a result when SEPARATE_VERSTAGE is not selected, there is no
entry point into romstage and romstage will not be started at all.

The solution is move out romstage_after_verstage.S from fsp1.1 driver
to skylake/romstage. And add CONFIG_PLATFORM_USES_FSP1_1 to fix the
build and boot issue with this change.

Besides that, rename the romstage_after_verstage to romstage_c_entry
in more appropriate naming convention after this fix.

Tested on SkyLake Saddle Brook (FSP 1.1) and KabyLake Rvp11 (FSP 2.0),
romstage can be started successfully.

a69ac7861b i2c/tpm: Ignore 0xFF bytes for status and burstCount
We've found that the SLB9645 TPM sometimes seems to randomly start
returning 0xFF bytes for all requests. The exact cause is yet unknown,
but we should try to write our TIS code such that it avoids bad
interactions with this kind of response (e.g. any wait_for_status()
immediately succeeds because all "status bits" are set in the response).
At least for status and burstCount readings we can say for sure that the
value is nonsensical and we're already reading those in a loop until we
get valid results anyway, so let's add code to explicitly discount 0xFF
bytes.

c2973d196d spi: Get rid of SPI_ATOMIC_SEQUENCING
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with
the ability to perform tx and rx of flash command and response at the
same time. Instead of introducing this notion at SPI flash driver layer,
clean up the interface to SPI used by flash.

Flash uses a command-response kind of communication. Thus, even though
SPI is duplex, flash command needs to be sent out on SPI bus and then
flash response should be received on the bus. Some specialized x86
flash controllers are capable of handling command and response in a
single transaction.

In order to support all the varied cases:
1. Add spi_xfer_vector that takes as input a vector of SPI operations
and calls back into SPI controller driver to process these operations.
2. In order to accomodate flash command-response model, use two vectors
while calling into spi_xfer_vector -- one with dout set to
non-NULL(command) and other with din set to non-NULL(response).
3. For specialized SPI flash controllers combine two successive vectors
if the transactions look like a command-response pair.
4. Provide helper functions for common cases like supporting only 2
vectors at a time, supporting n vectors at a time, default vector
operation to cycle through all SPI op vectors one by one.

41f6690239 drivers/spi: fix flash writes at page boundaries
There was an assumption that all SPI controllers could
consume a full page of data to write. However, that
assumption doesn't hold when spi_crop_chunk() indicates
sizes smaller than page size. If the requested offset isn't
page aligned from the start then writes will fail corrupting
data since a page boundary isn't honored.

The spansion driver needed quite a bit more work to honor
the spi_crop_chunk() result. It now mimics the other
driver's code. Also, needed to add spi_crop_chunk() to
marvell/bg4cd SoC to make google/cosmos build. SPI obviously
doesn't work on that platform, but it fixes the build error.

f1f322b1a8 pcf8523: Fix wrong initialization of several registers
In the case where the RTC is initialized after the battery is
completely drained the bits for power_mode and cof_selection are set up
with wrongly applied masks.
In the case where the RTC is re-initialized again with no power-loss
after the last initialization the bits for cap_sel, power_mode and
cof_selection are not shifted to the right position.

Both errors lead to a wrong initialization of the RTC and in turn to a
way larger current consumption (instead of 120 nA the RTC current rises
to over 2 µA).

This patch fixes both errors and the current consumption is in the right
range again.
