4668ba77ea soc/intel/common/lpss_i2c: simplify API and use common config structure
The apollolake and skylake had duplicate stanzas of code for
initializing the i2c buses. Additionally, they also had very
similar structures for providing settings for the i2c speed
control. Introduce a new struct lpss_i2c_bus_config and
utilize it in both apollolake and skylake thereby removing
the need for SoC-specific structres. The new structure is
used for initializing a bus fully as the lpss i2c API is
simplified in that lpss_i2c_init() is only required to be
called. The struct lpss_i2c_bus_config structure is passed
in for both initializing and filling in the SSDT information.
The formerly exposed functions are made static to reduce the
external API exposure.

ed14a4e0df soc/intel/skylake: move i2c voltage config to own variable
In preparation of merging the lpss i2c config structures on
apollolake and skylake move the i2c voltage variable to its
own field. It makes refactoring things easier, and then there's
no reason for a separate SoC specific i2c config structure.

d8bb69a451 soc/intel/skylake: fix memory access beyond array bounds
chip.h has a config array PcieRpClkReqNumber which corresponds
to a FSP UPD parameter, the size is currently set to 20.
However the size of PcieRpClkReqNumber UPD in FSP2.0 is 24,
so memcpy (config buffer to UPD buffer) in chip_fsp20.c will read
beyond the bounds of config array.
Hence set the size of PcieRpClkReqNumber array based on the FSP in use.

bc41ddd44e soc/intel/skylake: Add _ACx methods for TSR0 sensor for fan control
This patch updates below info,
[1] Delete the DPTF_CPU_ACTIVE_AC* values because these are not
being used. Hence, removing unnecessary defines.
[2] Add new DPTF_TSR0_ACTIVE_AC* temperature trip points for TSR0
external thermal sensor. These trip points are being used by _ACx
methods to control the fan speed on Skylake-U fan based Lars and
Kunimitsu platforms.
[3] Follow up patches are using DPTF_CPU_ACTIVE_AC* temperature trip
points in board specific acpi/dptf.asl (for lars, kunimitsu, etc) to
control the fan speed as per the CPU temperature trip points.
[4] Newly added _ACx methods for thermal sensor TSR0 in this patch
has nothing to do with DPTF_CPU_ACTIVE_AC*.

We can control fan speed using various different thermal sensors.
In this patch, we have added new _ACx methods for TSR0 thermal sensor.
We run the fan at different speeds to cool down the system at different
TSR0 temperatures.

Similarly, we considered CPU sensor temperature values and ran the fan
at different speeds to cool down the system.

2f3736e7ac soc/intel/{sky,apollo}lake: Wait until GPE is clear when reading
When reading+clearing a GPE for use as an interrupt we need to
re-read the status register and keep setting the clear bit until
it actually reads back clear.  Also add a 1ms timeout in case the
status never clears.

This is needed if a device sends a longer interrupt pulse and it
is still asserted when the "ISR" goes to clear the status.

ff8bf410d9 soc/intel/skylake: Implement Global Reset MEI message
As per ME BWG, there are two mechanism to generate a Global
Reset (resets both host and Intel ME), one is through CF9h
IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set,
PMC PCI offset ACh[20]. Another is to issue the Global Reset
MEI message. Because any attempts to cause global reset without
synchronizing the two sides might cause unwanted side effects,
such as unwritten flash data that will get destroyed if the
host were to cause a global reset without informing Intel ME
firmware, the recommended method is to send a Global Reset MEI
message when the following conditions are met:

The PCH chipset firmware just needs to complete the Intel ME
Interface #1 initialization and check the Intel ME HFSTS state
if Intel ME is not in ERROR state and is accepting MEI commands
then firmware should be able to use Global Reset MEI message to
trigger global reset.

Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9
write of 0x06 or 0x0E command with PCH ETR3 register bit [20]
to perform the global reset.

1222a73205 skylake: Add initial FSP2.0 support
Add Initial pieces of code to support fsp2.0 in skylake keeping
the fsp1.1 flow intact.

The soc/romstage.h and soc/ramstage.h have a reference to
fsp driver includes, so split these header files for
each version of FSP driver.

Add the below files,
car_stage.S:
	Add romstage entry point (car_stage_entry).
	This calls into romstage_fsp20.c and aslo handles
	the car teardown.
romstage_fsp20.c:
	Call fsp_memory_init() and also has the callback
	for filling memory init parameters.

Also add monotonic_timer.c to verstage.

With this patchset and relevant change in kunimitsu mainboard,
we are able to boot to romstage.

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)

Prepare Skylake for FSP2.0 support.

We do not use FSP-T in FSP2.0 driver, hence guard the
FspTempRamInit call under a switch.

In addition to the current early PCH configuration
program few more register, so all in all we do the following,
* Program and enable ACPI Base.
* Program and enable PWRM Base.
* Program TCO Base.
* Program Interrupt configuration registers.
* Program LPC IO decode range.
* Program SMBUS Base address and enable it.
* Enable upper 128 bytes of CMOS.
And split the above programming into into smaller functions.

Also, as part of bootblock_pch_early_init we enable decoding
for HPET range. This is needed for FspMemoryInit to store and
retrieve a global data pointer.

And also move P2SB related definitions to a new header file.

ffc9990ece acpi: Change device properties to work as a tree
There is a second ACPI _DSD document from the UEFI Forum that details
how _DSD style tables can be nested, creating a tree of similarly
formatted tables.  This document is linked from acpi_device.h.

In order to support this the device property interface needs to be
more flexible and build up a tree of properties to write all entries
at once instead of writing each entry as it is generated.

In the end this is a more flexible solution that can support drivers
that need child tables like the DA7219 codec, while only requiring
minor changes to the existing drivers that use the device property
interface.

This was tested on reef (apollolake) and chell (skylake) boards to
ensure that there was no change in the generated SSDT AML.

222381e390 skylake: Generate ACPI timing values for I2C devices
Have the Skylake SOC generate ACPI timing values for the enabled I2C
controllers instead of passing it in the DSDT with static timings.

The timing values are generated from the controller clock speed and
are more accurate than the hardcoded values that were in the ASL which
were originally copied from Broadwell where the controller is running
at a different clock speed...

Additionally it is now possible for a board to override the values
using devicetree.cb.  If zero is passed in for SCL HCNT or LCNT then
the kernel will generate its own timing using the same forumla, but if
the SDA hold time value is zero the kernel will NOT generate a correct
value and the SDA hold time may be incorrect.

This was tested on the Chell platform to ensure all the I2C devices on
the board are still operational with these new timing values.

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.

b25a45ca46 skylake: Add SD card device to configure card detect GPIO
Add a PCI driver for the skylake SD card device and have it generate
an entry in the SSDT for the card detect GPIO if it is provided by the
mainboard in devicetree.

This sets up a card detect GPIO configuration that will trigger an
interrupt on both edges with a 100ms debounce timeout and can wake the
SD controller from D3 state.

The GpioInt() entry is bound to the "cd-gpio" device property which will
be consumed by the kernel driver.

The resulting ACPI output in the SSDT will be combined with the SDXC
device declaration in the DSDT.

Example:

Scope (\_SB.PCI0.SDXC)
{
  Name (_CRS, ResourceTemplate () {
    GpioInt (Edge, ActiveBoth, SharedAndWake, PullNone, 10000,
             "\\_SB.PCI0.GPIO", 0, ResourceConsumer) { 35 }
  })
  Name (_DSD, Package () {
    ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
    Package () {
      Package () { "cd-gpio", Package () { \_SB.PCI0.SDXC, 0, 0, 1 } }
    }

66bd65d0f7 skylake: Add handler for finding ACPI path for GPIO
Add a handler for the Intel Skylake SOC to return the ACPI path for
GPIOs.  Since all GPIOs are handled by the same controller they all
have the same ACPI path and this is a simple handler that just returns
a pointer to the GPIO device that is defined in the DSDT.

2f6fb9f5f9 skylake: Add ACPI device name handler
Add a global ACPI device name handler for the Skylake SOC that will
translate skylake device paths into an ACPI path that matches the
device objects delcared in the DSDT at soc/intel/skylake/acpi/*.

The skylake implementation uses a global acpi_name handler for the
SOC and it is not necessary to add a function to every device.

This function is used by device drivers calling acpi_device_name()
and acpi_device_path() to generate ACPI AML in the SSDT.

6ec72c9b4f drivers/uart: Use uart_platform_refclk for all UART models
Allow the platform to override the input clock for the UART by
implementing the routine uart_platform_refclk and setting the Kconfig
value UART_OVERRIDE_REFCLK.  Provide a default uart_platform_refclk
routine which is disabled when UART_OVERRIDE_REFCLK is selected.  This
works around ROMCC not supporting weak routines.

Testing on Galileo:
*  Edit the src/mainboard/intel/galileo/Makefile.inc file:
   *  Add "select ADD_FSP_PDAT_FILE"
   *  Add "select ADD_FSP_RAW_BIN"
   *  Add "select ADD_RMU_FILE"
*  Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
*  Place the pdat.bin files in the location specified by
   CONFIG_FSP_PDAT_FILE
*  Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
*  Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
   UEFIPAYLOAD.fd
*  Testing is successful when CorebootPayloadPkg is able to properly
   initialize the serial port without using built-in values.

8c09377dea timestamp: Remove HAS_PRECBMEM_TIMESTAMP_REGION Kconfig
This patch generalizes the approach previously used for ARM32
TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
memlayout.ld. This allows us to get rid of the explicit Kconfig for the
TIMESTAMP region, reducing configuration redundancy and avoiding
confusion when setting up future boards.

(Removing armv4/bootblock_simple.c because it references this Kconfig
and it is a dead file that I just forgot to remove in CL:12076.)

59ff3400b0 Kconfig: Move defaults for CBFS_SIZE
We want the question for CBFS size to be next to the rom size in the
mainboard directory, but that doesn't seem to work for how people
want to set the defaults.  Instead of having the list of exceptions
to the size, just set the defaults at the end of kconfig.

- Move the defaults for chipsets not setting HAVE_INTEL_FIRMWARE into
the chipset Kconfigs (gm45, nehalem, sandybridge, x4x)
- Override the default for HAVE_INTEL_FIRMWARE on skylake.
- Move the HAVE_INTEL_FIRMWARE default setting into the firmware
Kconfig file
- Move the location of the default CBFS_SIZE=ROM_SIZE to the end of
the top level kconfig file, while leaving the question where it is.

Test=rebuild Kconfig files before and after the change, verify that
they are how they were intended to be.

Note: the Skylake boards actually changed value, because they were
picking up the 0x100000 from HAVE_INTEL_FIRMWARE instead of the
0x200000 desired.  This was due to the SOC_INTEL_SKYLAKE being after
the HAVE_INTEL_FIRMWARE default.  Affected boards were:
Google chell, glados, & lars and Intel kunimitsu.

6c1bf27dae intel/skylake: disable ACPI PM Timer to enable XTAL OSC shutdown
Keeping ACPI PM timer alive prevents XTAL OSC shutdown in S0ix
which has a power impact.

Based on a DT variable, this patch disables the ACPI PM timer
late in the boot sequence - disabling earlier will lead to a hang
since the FSP boot flow needs this timer. This also hides the ACPI PM
timer from the OS by removing from FADT table. Once the ACPI PM timer
is disabled, TCO gets switched off as well.

5535cead09 intel/skylake: Disable SaGv in recovery mode
This patch disables the SaGv feature in recovery mode. Since the memory
training happens at both low and high frequency points when SaGv is
enabled, recovery mode boot time increases by 5 seconds. To reduce this
5 second increase, the SaGv feature is disabled in recovery mode.

The value "0" here means SaGv disable.
Following is the table for same.

0=Disabled (SaGv disabled)
1=FixedLow (Fixed to low frequency)
2=FixedHigh (Fixed to High frequency)
3=Enabled (SaGv Enabled. Dynamically changes)

BRANCH=None
BUG=chrome-os-partner:48534

it will request for an additional reset.On next boot system resume

Hence an additional 1 reset require to identify original state.

its original status and avoid 1 extra reboot.

ed8a723f42 intel/skylake: add nhlt support
The use of a NHLT table is required to make audio work
on the skylake SoCs employing the internal DSP. The table
describes the audo endpoints (render vs capture) along with
their supported formats. These formats are not only dependent
on the audio peripheral but also hardware interfaces. As such
each format has an associated blob of DSP settings to make
the peripheral work. Lastly, each of these settings are provided
by Intel and need to be generated for each device's hardware
connection plus mode/format it supports. This patch does not
include the dsp setting blobs.

The current supported connections:
- digital mic array 2 channel
