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

As solution, FSP introduced a new UPD SpiFlashCfgLockDown to skip

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

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.

In order to save more power by shutting down clocks add the
ability to optionally clock gate the 8254 programmable interrupt
timer. When doing this the platforms lose their "PC"-ness which
certain payloads and OSes rely on such as SeaBIOS.

Intel Speed Shift Technology is a new mechanism that replaces
Legacy P-state. ISST allows OS hints about energy/performance

1. Optimization frequency seclection for low residency workloads,
no longer a static knee point.
2. Optimized frequency selection for best energy to performance
trade offs.
3. Kick down frequency (from idle) fpr best responsiveness while

Coreboot's responsiblity is to configure MSR 0x1AA ISST_EN bits
which will reflect in CPUID.06h:EAX[Bit 7] that driver checkes

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.
BRANCH=none

TEST=Build for skylake board with the PmTimerDisabled policy in
devicetree set to 1.
