Both PCH types are very different, and mixing the code for both together
isn't useful. Make `ISLP` return a constant, so that IASL can fold it.

_DCS, _DGS and _DSS are required by specification. However,
we never implemented them properly, and no OS driver com-
plained yet. So we stub them out and keep the traditional
behavior in case an OS driver checks for their existence.
The old implementations also only returned static values as
there never was any write to their GNVS variables. The TRAP()
that was called in one place is actually implemented by some
ThinkPad's SMI handler as docking event. However, as the call
precedes these SMI handlers in coreboot history, it's most
likely an accident.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

On newer kernels (> 4.9 LTS), the GPIO ACPI device's interrupt
resource causes an interrupt storm which prevents the CPU
from properly idling, significantly increasing power consumption.
This was fixed for soc/broadwell (which also supports lynxpoint-lp)
by removing the interrupt resource, so apply the same fix here.
Original fix: https://chromium-review.googlesource.com/203645
Test: build/boot google/wolf, verify CPU0 idles correctly and
power consumption drop via powertop in kernels 4.16.18 and 5.x.

This reverts commit 01787608670adec26fcea48173e18395e51c790e.
AMD: Dropping the _HID of PCI root bus doesn't work well and people
started to notice the breakage.
Intel: These platforms have a devicetree switch to choose between PCI
and ACPI modes. In the former case we need _ADR, but in the latter _HID
as the PCI devices are hidden.
The conflicting use of _ADR and _HID still needs to be fixed before
we can bump our IASL version.

The existing SATA ACPI code for Lynx Point implements some methods and
devices, but not completely. These methods are optional and only used in
IDE mode. The code was likely copied from bd82x6x, where it has since
been removed.
As a result, many remarks produced by iasl about unreferenced objects
are eliminated.
Tested on an ASRock H81M-HDS and an Acer C720. No issues with SATA

Currently the throttle event handler method THRM is defined as an
extern on the intel bd82x6x and lynxpoint chipsets, then defined
again in the platform with thermal event handling. In newer versions
of IASL, this generates an error, as the method is defined in two
places. Simply removing the extern causes the call to it to fail on
platforms where it isn't actually defined, so add a preprocessor define
where it's implemented, and only call the method on those platforms.
This also requires moving the thermal handler, which now includes
the define to before the gnvs asl file.
TEST=Build before and after, make sure correct code is included.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

The SerialIO DwordIo() definition is fixed up before returning
it in the serialio device _CRS method, so the values that are set
in the raw ASL are not actually used.
However modern versions of IASL do not like that the RangeLength is
set to zero and will fail to compile. Set this value to 1 to make
IASL stop complaining, but the real value is still fixed up in _CRS
so this has no real effect on the end result.

Remove the bit of code that was putting the SerialIO devices into
D3Hot state when they are switched from PCI to ACPI mode. Instead,
add the appropriate ACPI Methods to allow the kernel to control the
power state of the device.
The problem seems to be that if the device is put in D3Hot state
before it is switched from PCI to ACPI mode then it does not properly
export its PCI configuration space and cannot be woken back up.
Adding the ACPI Methods for _PS0/_PS3 allows the kernel to transition
the device into D0 state only when it is necessary to communicate with
the device, then put it back into D3Hot state.

The end of the _PS0 method that is supposed to transition the
XHCI device to D0 state is instead putting it in D3 state.
This triggers a PME_B0 GPE which causes a Notify to the XHCI
ACPI Device in the kernel and that increments the wakeup counter
and causes aborted suspends.
Instead if we just leave the device in D0 where it should be
after executing this function then the PME_B0 is not generated
and the kernel does not see a wakeup on XHCI.
Similarly I changed the _PS3 method to always put the device in
D3 at the end of the method, rather than depending on the state
to be D3 at the start.
Before this change the kernel would see the following sequence
when trying to suspend when the XHCI controller is in D3cold:
kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS0] (Node ffff88017802bf28)
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [XHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802bc30
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [EHCI] (Device) Value 0x02 (Device Wake) Node ffff88017802b8e8
kernel: evmisc-0169 [07] ev_queue_notify_reques: Dispatching Notify on [HDEF] (Device) Value 0x02 (Device Wake) Node ffff88017802b1b8

kernel: PM: Wakeup pending, aborting suspend
kernel: last active wakeup source: 0000:00:14.0
Now it does not get a notification (due to PME_B0) when going to D0
on the way into suspend. XHCI goes from D3cold to D0 (in order to
be able to read mmio) and then back to D3hot before suspend.

The recommended value in docs is D2, but lynxpoint XHCI does not even
support D2 state which causes the kernel to think this device cannot
be used as a wake source:
kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI
kernel: ACPI: Device does not support D2
kernel: xhci_hcd 0000:00:14.0: System wakeup disabled by ACPI
Additionally this means the kernel will never put the device into D3
state by itself. There is SMI code that will put the device into D3
before suspend so advertising D3 here should be correct.
With this change the kernel will put the controller into D3 on suspend
and back to D0 on resume, including executing the ACPI methods
for _PS0/_PS3 that contain chipset specific workarounds.
In addition add a _PSC method to directly return the D state from the
device registers. With ALL USB devices removed the XHCI controller
goes into D3 state and the kernel can have a hard time determining
the state of the device at boot.
A kernel compiled with CONFIG_ACPI_DEBUG=y and module parameters
acpi.debug_layer=0x7f acpi.debug_level=0x2f can be used to see
what ACPI methods are executed:
kernel: xhci_hcd 0000:00:14.0: System wakeup enabled by ACPI
kernel: ACPI: Execute Method [\_SB_.PCI0.XHCI._PS3] (Node ffff8801000a7f50)

In order to report whether coreboot enabled a SerialIO device
in ACPI mode we had been relying on reading NVS in the _STA
method for the SerialIO device.
The ACPI _STA method has restrictions on what it can access
and is unable to access OperationRegions outside its scope
which means it should not be trying to read NVS.
This change adds a new SSDT to the ACPI tables and fills it
with constants that indicate whether or not a device is enabled
in ACPI mode.
The ACPI code is changed to read these variables from the
SSDT and use that instead of trying to query a variable in NVS.
Attempt to use lpt-clk driver to probe the
device clocks for SerialIO devices and see that the kernel
does not complain about accessing the GNVS region.

This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers.
There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.
These devices must be put into "ACPI Mode" in order to take
advantage of S0ix. When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS. When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.
Note that is is not entirely complete yet. We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.
This is hard to test right now because our kernel does not support
any of these devices in ACPI mode. I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree. With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.
I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.
