This change adds support for allocating resources above the 4G
boundary by making use of memranges for resource windows enabled in
the previous CL.
It adds a new resource flag IORESOURCE_ABOVE_4G which is used in the
following ways:
a) Downstream device resources can set this flag to indicate that they
would like to have their resource allocation above the 4G
boundary. These semantics will have to be enabled in the drivers
managing the devices. It can also be extended to be enabled via
devicetree. This flag is automatically propagated by the resource
allocator from downstream devices to the upstream bridges in pass
1. It is done to ensure that the resource allocator has a global view
of downstream requirements during pass 2 at domain level.
b) Bridges have a single resource window for each of mem and prefmem
resource types. Thus, if any downstream resource of the bridge
requests allocation above 4G boundary, all the other downstream
resources of the same type under the bridge will be allocated above 4G
boundary.
c) During pass 2, resource allocator at domain level splits
IORESOURCE_MEM into two different memory ranges -- one for the window
below 4G and other above 4G. Resource allocation happens separately
for each of these windows.
d) At the bridge level, there is no extra logic required since the
resource will live entirely above or below the 4G boundary. Hence, all
downstream devices of any bridge will fall within the window allocated
to the bridge resource. To handle this case separately from that of
domain, initializing of memranges for a bridge is done differently
than the domain.
Limitation:
Resources of a given type at the bridge or downstream devices
cannot live both above and below 4G boundary. Thus, if a bridge has
some downstream resources requesting allocation for a given type above
4G boundary and other resources of the same type requesting allocation
below 4G boundary, then all these resources of the same type get
allocated above 4G boundary.
BUG=b:149186922
TEST=Verified that resources get allocated above the 4G boundary
correctly on volteer.

This change updates the resource allocator in coreboot to allow using
multiple ranges for resource allocation rather than restricting
available window to a single base/limit pair. This is done in
preparation to allow 64-bit resource allocation.
Following changes are made as part of this:
a) Resource allocator still makes 2 passes at the entire tree. The
first pass is to gather the resource requirements of each device
under each domain. It walks recursively in DFS fashion to gather the
requirements of the leaf devices and propagates this back up to the
downstream bridges of the domain. Domain is special in the sense that
it has fixed resource ranges. Hence, the resource requirements from
the downstream devices have no effect on the domain resource
windows. This results in domain resource limits being unmodified after
the first pass.
b) Once the requirements for all the devices under the domain are
gathered, resource allocator walks a second time to allocate resources
to downstream devices as per the requirements. Here, instead of
maintaining a single window for allocating resources, it creates a
list of memranges starting with the resource window at domain and then
applying constraints to create holes for any fixed resources. This
ensures that there is no overlap with fixed resources under the
domain.
c) Domain does not differentiate between mem and prefmem. Since they
are allocated space from the same resource window at the domain level,
it considers all resource requests from downstream devices of the
domain independent of the prefetch type.
d) Once resource allocation is done at the domain level, resource
allocator walks down the downstream bridges and continues the same
process until it reaches the leaves. Bridges have separate windows for
mem and prefmem. Hence, unlike domain, the resource allocator at
bridge level ensures that downstream requirements are satisfied by
taking prefetch type into consideration.
e) This whole 2-pass process is performed for every domain in the
system under the assumption that domains do not have overlapping
address spaces.
Noticeable differences from previous resource allocator:
a) Changes in print logs observed due to flows being slightly
different.
b) Base, limit and size of domain resources are no longer updated
based on downstream requirements.
c) Memranges are used instead of a single base/limit pair for
determining resource allocation.
d) Previously, if a resource request did not fit in the available
base/limit window, then the resource would be allocated over DRAM or
any other address space defeating the principle of "no overlap". With
this change, any time a resource cannot fit in the available ranges,
it complains and ensures that the resource is effectively disabled by
setting base same as the limit.
e) Resource allocator no longer looks at multiple links to determine
the right bus for a resource. None of the current boards have multiple
buses under any downstream device of the domain. The only device with
multiple links seems to be the cpu cluster device for some AMD
platforms.
BUG=b:149186922
TEST=Verified that resource allocation looks correct based on
addresses assigned on Volteer.

This reverts commit cc805d9dd6.
Advertising certain Windows versions triggers different paths in
the OS. As there may also be device specific quirks in the OS, such
changes need to be tested thoroughly on all affected devices.
There was at least one very subtle regression introduced by this.
When Linux sees "Windows 2012" support advertised, it disables the
`acpi_video` backlight controls, at least on devices with Intel IGD.
Without user-space handling the ACPI events, keyboard backlight
controls stop working.
Moreover, the commit message didn't state any reason for this change.
Why was it merged?

controller (if supported by platforms)
lpc_enable_spi_rom() - Enables SPI ROM
This split is done to allow setting of MMIO base independent of ROM
enable bits. On platforms like Picasso, eSPI base is determined by the
same register and hence eSPI can set the BAR without having to touch

We only write to the IOSAV LFSR registers twice, but we do so between

might as well do the two oddball LFSR register writes after we have
programmed the always-written-to group of four registers. That way,
subsequent changes can reproducibly replace the four writes with a

Transfer sequence used by SPI-Flash application present in CB/DC.
1. Assert CS through GPIO
2. Data transfer through QSPI (involves construction of command
descriptor for multiple read/write transfers)
3. De-assert CS through GPIO.
With above sequence, in DMA mode we dont have the support for read
transfers that are not preceded by write transfer in QSPI controller.
Ex: "write read read read" sequence results in hang during DMA transfer,
where as "write read write read" sequence has no issue.
As we have application controlling CS through GPIO, we are making
fragment bit "set" for all transfers, which keeps CS in asserted
state although the ideal way to operate CS is through QSPI controller.

the need to declare a not-present device off and/or extraneous PNP
device errors about a not-present device.

LTE module Fibocom L850-GL is lost after idle overnight, with this workaround, host will not initiate U3 wakeup at the same time with device, which will avoid the race condition.
Disable XHCI LFPS power management. If the option is set in the devicetree, the bits[7:4] in XHCI MMIO BAR + offset 0x80A4 (PMCTRL_REG) will be updated from default 9 to 0.

TEST=build coreboot with DisableXhciLfpsPM being set to 1 and flash
the image to the device. Run following command to check if
bits[7:4] are set 0:

C-State latency table was exposed by both intel-idle driver and
BIOS/coreboot. And table in Kernel was used before.
After kernel patch (https://patchwork.kernel.org/patch/11290319/),
only BIOS/coreboot exposes C-State latency table through _CST.
As current C-State latency table info is not correct for Tigerlake,
update proper info according to BWG and reference code.
- Update latency: CpuPowerMgmt.h
Use BIOS reference code as values in BWG is not up-to-dated
- Remove MSR program for latency: BWG 4.6.4.3.4

- TGL BWG #611569 Rev 0.7.6
