015b3dc124 soc/intel/skylake: Add device settings for PL4 power limit
PL4 is a preemptive CPU package peak power limit,it will never be exceeded.
Power is preemptively lowered before limit is reached.

This change provides option in devicetree and feeds FSP PowerLimit4 UPD for
power limit purpose.

b54d15487a soc/intel/skylake: Support PL1 override option
In legacy mode, DPTF on some systems may rely on MMIO to control PL1
settings. However, MSR PL1 also contributes to the decision of max
PL1 power; and in the current design, the lower value takes effect.
In order to align MMIO and MSR settings, a tdp_pl1_override option is
added to override the MSR PL1 limitation.

TEST=1. Write PL1 override setting in devicetree.cb

This change permits the subsystem ID to be specified via Kconfig for the
devices on the SoC.

Some devices are getting zero'ed subsystem IDs because the unset (and thus
zero'ed) config options are overwriting the fsp defaults. With this change
the fsp defaults will only be overwritten by non-zero config values.

2afe4dc075 soc/intel/skylake: Enable VT-d and X2APIC
We use the usual static addresses 0xfed90000/0xfed91000 for the GFX
IOMMU and the general IOMMU respectively. These addresses have to be
configured in MCHBAR registers (maybe, who knows, the blob is undocu-
mented), advertised to FSP and reserved from the OS.

The new devicetree option `ignore_vtd` allows to retain the old beha-
viour (do whatever pre-set UPD values suggest).

We also let FSP set up distinct BDFs for messages originating from the
I/O-APIC and the HPET.

f5116952bb soc/intel/skylake: Limit xDCI feature when VBOOT is enabled
Use the common xDCI function to check if the controller is allowed
in the current mode before enabling it.  Otherwise, disable the
PCI device if it has been enabled in devicetree.

To make the SOC behavior consistent the XdciEnable config option
is removed in favor of direct control by devicetree.cb and the
mainboards that had defined it were adjusted accordingly.

This was tested on an Eve board with xDCI enabled in devicetree.cb
to ensure the xDCI device is enabled in developer mode and disabled
in normal mode.

03937391bc soc/intel/skylake: Add config for enabling LTR for PCIe Root port
There are a lot errors reported by AER driver for root port 0.
The erors are being caused by an unsupported request from the
device to the upstream port. Enabling LTR on the root port stops
these errors, it is because LTR is enabled on the device side but
not on the root port and hence root port was logging the LTR messages
from the device as unsupported.

The PCIe base spec (v3.1a) section 6.18 also states that:
LTR support is discovered and enabled through reporting and control
registers described in Chapter 7. Software must not enable LTR in an
Endpoint unless the Root Complex and all intermediate Switches indicate
support for LTR. Note that it is not required that all Endpoints support
LTR to permit enabling LTR in those Endpoints that do support it. When
enabling the LTR mechanism in a hierarchy, devices closest to the
Root Port must be enabled first.

If an LTR Message is received at a Downstream Port that does not
support LTR or if LTR is not enabled, the Message must be treated
as an Unsupported Request. FSP has a UPD for enabling/disabling
LTR on root port, use the same for configuring LTR on PCIe root ports.

TEST=After enbaling LTR on port 0 on the MB devicetree, No errors reported

0f2dd1eff9 include/device: Split i2c.h into three
Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.

* `i2c.h`        - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
                   per board, devicetree independent I2C interface
* `i2c_bus.h`    - will become the devicetree compatible interface for
                   native I2C (e.g. non-SMBus) controllers

4859ce0b81 soc/intel/skylake: Skip Spi Flash Lockdown from FSP
coreboot was setting SPI FPR register to protect the
mrc_cache data range stored in flash. This programming was being done
after FSP Notify 1.
But, FSP was locking the SPI by setting FLOCKDN Bit during Notify
phase 1, due to which coreboot was unable to protect that range.

As solution, FSP introduced a new UPD SpiFlashCfgLockDown to skip
the lockdown of flash on interest of bootloader. Set that UPD to 0
to skip the lockdown of FAST_SPI flash from FSP.

The same is being done from coreboot after end of Post at finalize.c
file.

BUG=b:63049493
BRANCH=none
TEST=FPR can be set properly to protect the mrc_cache range. The
issue reported in the bug doesn't come when both software and
hardware WP is enabled with this patch.

1fe32d6bb2 soc/intel/skylake: Split AC/DC settings for Deep Sx config
Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled
in both DC and AC states.  However since using Deep S3 disables some
expected features like wake-on-USB it is not always desired to enable the
same state in both modes.

To address this split the setting and add a separate config for Deep Sx in
AC and DC states.

All motherboards that set this config were updated, but there is no actual
change in behavior in this commit.

BUG=b:36723679
BRANCH=none
TEST=This commit has no runtime visible changes, I verified on Eve that the
Deep SX config registers are unchanged, and it compiles for all affected boards.

7de031759b soc/intel/skylake: Add SGX initialization
This patch implements SGX initialization steps in coreboot per Intel SGX
BWG rev 2.0.8 for Kaby Lake SoC. If enabled on a Kabylake device, SoC
capability and PRM (processor reserved memory) of desired size (needs to
be configured through PrmrrSize) are provisioned for later software
stack to use SGX (i.e., run SGX enclaves).

One issue is still puzzling and needs to be addressed: by calling
configure_sgx() in cpu_core_init() which is the per-thread function, SGX
is always failing for thread 0 but is successful for other 3 threads.
I had to call configure_sgx() again from soc_init_cpus() which is the
BSP-only function to make it enable on the BSP.

Another pending work is the implementation for the Owner Epoch update
which shall be added later.

BUG=chrome-os-partner:62438
BRANCH=NONE
TEST=Tested on Eve, verified SGX activation is successful on all threads.

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.
