flash_programmer_probe is a property of the spi flash driver and does
not belong in the spi_slave structure. Thus, make
spi_flash_programmer_probe a callback from the spi_flash_probe
function. Logic still remains the same as before (order matters):
1. Try spi_flash_programmer_probe without force option
2. Try generic flash probing
3. Try spi_flash_programmer_probe with force option
If none of the above steps work, fail probing. Flash controller is
expected to honor force option to decide whether to perform specialized

RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.
New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.
spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

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

PMC PCI offset ACh[20]. Another is to issue the Global Reset

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

Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9

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.

Calling halt in poweroff when in SMM prevents SLP_SMI to be triggered
preventing the system from entering sleep state. Fix this by calling
halt only if ENV_SMM is not true.

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.

Using malloc() in SPI code is unnecessary as there's only
one SPI device that the SoC support code handles: boot
device. Therefore, use CAR to for the storage to work around
the current limiations of the SPI API which expects one to
return pointers to objects that are writable. Additionally,
include the SPI support code as well as its dependencies in
all the stages.

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.

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)

There is a lot of code that is being referred to in bootblock but
resides under skylake/romstage folder. Hence move this code
into skylake/bootblock, and update the relevant header files
and Makefiles.

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.
