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.

BUG=b:65570878
TEST=After enbaling LTR on port 0 on the MB devicetree, No errors reported
     by AER driver for root port 0.

fbf1018805 soc/intel/skylake: Lock sideband access in coreboot and not in FSP
The Sideband Acces locking code is skipped from FSP by setting an
FSP-S UPD called PchSbAccessUnlock. This locking is being done in
coreboot during finalize.c.

This is done because coreboot was failing to disable HECI1 device
using Sideband interface during finalize.c if FSP already locks
the Sideband access mechanism before that.

So, as a solution, coreboot passes an UPD to skip the locking
in FSP, and in finalize.c, after disabling HECI, it removes the
Sideband access.

resume is currently broken for all skylake/kabylake boards. All the
skylake/kabylake boards store external stage cache in TSEG, which is
relocated post MP-init. Thus, if FSP loading and initialization is
done after MP-init, then ramstage is not able to:
1. Save FSP component in external stage cache during normal boot, and
2. Load FSP component from external stage cache during resume

In order to fix this, ensure that FSP loading happens separately from
FSP initialization. Add fsp_load callback for pre_mp_init which ensures
that the required FSP component is loaded/saved from/to external stage
cache.

eedf6d8aa8 soc/intel/skylake: Disable Legacy PME for Root ports
Legacy PME are enabled by default in FSP UPD region.
When Legacy PME is enabled, then an SCI is generated and should be
handled by OS and BIOS/Coreboot in collboration. OS requires some
ACPI methods (eg _L69) which help to determine the wake source and also
to clear some registers. But this infrastructure is not present as of
now in coreboot and also linux handles PMEs natively.

Hence the SCI was never handled by OS and the status bits were never
cleared i.e., PCI_EXP_STS.

For this reason the level triggered SCI will remain active and the
system will wake up as soon as it enters S3.

To fix this, diabled Legacy PME (PmSci for Root ports).

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.
