8416460318 intel/{skylake,apollolake}: Enable signalling of error condition
Testing for "devfn < 0" on an unsigned doesn't work, and i2c_bus_to_devfn
returns an int (with -1 for "error"), so use int for devfn.

Adapt Change-Id I7d1cdb6af4140f7dc322141c0c018d8418627434 to fix more
instances.

64606cea93 soc/intel/skylake: don't hardcode GPE0 standard reg
While using '3' is fine for the standard gpe0 for skylake, I want
to make sure anyone that copies this code doesn't tweak GPE0_REG_MAX
without the hard coded index. If that does happen now things will
still work, but it may just not match the hardware proper.

3bfe3404df intel/skylake: Add support to enable wake-on-usb attach/detach
Three things are required to enable wake-on-usb:
1. 5V to USB ports should be enabled in S3.
2. ASL file needs to have appropriate wake bit set.
3. XHCI controller should have the wake on attach/detach bit set for the
corresponding port in PORTSCN register.

Only part missing was #3.

This CL adds support to allow mainboard to define a bitmap in
devicetree corresponding to the ports that it wants to enable
wake-on-usb feature. Based on the bitmap, wake on attach/detach bits in
PORTSCN would be set by xhci.asl for the appropriate ports.

9a20551b7e soc/intel/skylake: Handle platform global reset
In FSP1.1 all the platform resets including global was handled
on its own without any intervention from coreboot.
In FSP2.0, any reset required will be notified to coreboot
and it is expected that coreboot will perform platform reset.

Hence, implement platform global reset hooks in coreboot. If Intel
ME is in non ERROR state then MEI message will able to perform
global reset else force global reset by writing 0x6 or 0xE to
0xCF9 port with PCH ETR3 register bit [20] set.

BUG=none
BRANCH=none
TEST=Verified platform global reset is working with MEI
message or writing to PCH ETR3.

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.

BUG=none
BRANCH=none
TEST=Verified Global Reset MEI message is able to perform platform
global issue in ME good state.

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)

cf73c1317d skylake: Do FspTempRamInit only for FSP1.1 & tidy up PCH early init
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.

TEST=Build and boot Kunimitsu

a7b97510ae soc/intel/skylake: Clean up SoC ASL code.
List of changes done here in this patch

1. Remove CARD definition from EMMC and SD Card Controller in scs.asl
since _RMV method does not get evaluated while setting up removable
attribute in sysfs in kernel.
"cat /sys/block/mmcblk1/removable" this command always returns 0.

This CARD Device includes _ADR which follows SDIO Bus format. But,
SD/EMMC sits on PCI Bus.
Hence this CARD Device specific _ADR code is also not needed.

2. Remove Base Address for ACPI debug output memory buffer in
systemagent.asl as it is not getting used throughout the code.
