In bootblock, cpu flex ratio is set to non-turbo max.
In FSP UPD, if CpuRatioOverride is zero, then it tries to program cpu
ratio to zero. Since it is different than the non-zero value programmed
in bootblock, FSP gives reset.
To avoid the reset, set FSP UPD for CPU flex ratio override to that
value as set in bootblock.

If prmrr base is non-zero value, then top_of_ram is prmrr base.

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).

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.

1. Re-factor MRC cache driver to properly select RW_MRC_CACHE or
RECOVERY_MRC_CACHE based on the boot mode.
- If normal mode boot, use RW_MRC_CACHE, if available.
- If recovery mode boot:
- Retrain memory if RECOVERY_MRC_CACHE not present, or recovery is
requested explicity with retrain memory request.
- Use RECOVERY_MRC_CACHE otherwise.
2. Protect RW and RECOVERY mrc caches in recovery and non-recovery boot
modes. Check if both are present under one unified region and protect
that region as a whole. Else try protecting individual regions.
3. Update training data in appropriate cache:
- Use RW_MRC_CACHE if normal mode.
- Use RECOVERY_MRC_CACHE if present in recovery mode. Else use
RW_MRC_CACHE.
4. Add proper debug logs to indicate which training data cache is used
at any point.
BUG=chrome-os-partner:59352
BRANCH=None
TEST=Verified that correct cache is used in both normal and recovery
mode on reef.

chip.h has a config array PcieRpClkReqNumber which corresponds
to a FSP UPD parameter, the size is currently set to 20.
However the size of PcieRpClkReqNumber UPD in FSP2.0 is 24,
so memcpy (config buffer to UPD buffer) in chip_fsp20.c will read
beyond the bounds of config array.
Hence set the size of PcieRpClkReqNumber array based on the FSP in use.

This patch updates below info,
[1] Delete the DPTF_CPU_ACTIVE_AC* values because these are not
being used. Hence, removing unnecessary defines.
[2] Add new DPTF_TSR0_ACTIVE_AC* temperature trip points for TSR0
external thermal sensor. These trip points are being used by _ACx
methods to control the fan speed on Skylake-U fan based Lars and
Kunimitsu platforms.
[3] Follow up patches are using DPTF_CPU_ACTIVE_AC* temperature trip
points in board specific acpi/dptf.asl (for lars, kunimitsu, etc) to
control the fan speed as per the CPU temperature trip points.
[4] Newly added _ACx methods for thermal sensor TSR0 in this patch
has nothing to do with DPTF_CPU_ACTIVE_AC*.
We can control fan speed using various different thermal sensors.
In this patch, we have added new _ACx methods for TSR0 thermal sensor.
We run the fan at different speeds to cool down the system at different
TSR0 temperatures.
Similarly, we considered CPU sensor temperature values and ran the fan
at different speeds to cool down the system.

When doing long transcations on an I2C bus at standard speed we saw
that long transactions could go over the 4ms limit while waiting for
it to complete on the bus.
Increase this so we can use standard speed for testing and debug in
firmware. (as there is no way to force standard speed in the kernel)

When reading+clearing a GPE for use as an interrupt we need to
re-read the status register and keep setting the clear bit until
it actually reads back clear. Also add a 1ms timeout in case the
status never clears.
This is needed if a device sends a longer interrupt pulse and it
is still asserted when the "ISR" goes to clear the status.
