By default legacy ISA IRQs use edge triggering. Depending on what
devices are used the IRQ types might need to be changed. We add a
setting to the device tree to allow the mainboard to configure the IRS
IRQs.

Angel Pons ec6e03e4d8 AGESA f14/f15tn/f16kb: Deduplicate RAM settings
On AGESA f14/f15tn, various RAM-related options were defined in an enum.
However, the preprocessor mess can't compare enum values. To make AGESA
build, each board redefined them as macros, shadowing the enum elements.
Clean this up by replacing the enums with macros in AGESA headers, and
delete the now-redundant redefinitions from all the mainboards.

Note that AGESA f16kb already uses macros, but each mainboard still had
commented-out definitions. Remove them as well, as they are unnecessary.

TEST=Use abuild --timeless to check that all AGESA f14/f15tn/f16kb
mainboards result in identical coreboot binaries.

Da Lao 56f5cc7ee3 ec/lenovo/h8: Config the ec hardware ids for newer thinkpads
Currently coreboot is using the ec hardware id IBM0068 for all
thinkpads, but for newer thinkpads the id maybe LEN0068 or LEN0268.
On Windows, the Lenovo Vantage app can't get battery details when using
IBM0068. This patch config this id by motherboard. The hardware IDs for
the following models can be found by searching for disassembled
dsdt.asl on vendor BIOS:

The X230, like its larger cousins, has a docking connector. However,
it lacks the "docking_supported" flag in devicetree, so add it.

Piotr Kleinschmidt af90a1e6af mb/pcengines/apu1/platform_cfg.h: Unset UsbRxMode to avoid platform reset issue
On PC Engines apu1 there were issues with cold reset. Platform hangs
in boot path after performing reset using CF9h.
CB:10549 (amd/sb800: Make UsbRxMode per-board customizable)
mentions a similar issue, and added a configuration macro for it.
That error is also described in AMD SB800 Family Product Errata,
section 15 USB Resets Asynchronously With Port CF9h Hard Reset.

This workaround simply non-execute USB configuration during boot
and hence no reset via CF9h is done.

TEST=perform multiple cold resets and see if platform boots

It also adds $(DEVICETREE_STATIC_C) to the c-deps for each stage so

Duncan Laurie 2d0655008f soc/intel/tigerlake: Provide SoundWire controller properties
The Intel Tigerlake SoundWire controller has 4 master links which
are configured differently depending on the external crystal oscillator
which is connected to the PCH.

This function will read the PCH PMC EPOC register to determine the
frequency and then fill out the master link entries with the correct
table values.

The frequency is also provided directly in a custom "ip-clock" property
which will be added to the link descriptor and passed to the OS driver
so it can know the clock rate of the master.

Duncan Laurie c2891f15fd drivers/intel/soundwire: Add Intel SoundWire controller driver
This driver provides support for Intel SoundWire controllers.  It is
intended to be used by multiple Intel SoCs and relies on retrieving
controller/master information from the SoC itself.  As such it
provides a function that must be implemented by the SoC to fill out
this structure.

The Intel SoundWire driver in the Linux kernel expects firmware to
inform it which master links are unused by adding a custom property
to the link descriptor.  This is done by looking for any children
attached to the device that use each link and disabling the ones
that are unused.

Mainboards will enable this driver and define the controller in
devicetree.cb in order provide the required ACPI tables, but the
mainboard should not need to provide any configuration itself as that
should all come from the SoC directly.

This was tested with the volteer board by adding this controller and a
codec to devicetree.cb and ensuring that the properties are all present,
including the custom properties for the device clock and quirk mask for
disabled links.

The PMC EPOC register indicates which external crystal oscillator is
connected to the PCH.  This frequency is important for determining the
IP clock of internal PCH devices.

Add definitions that allow this register to be read and extract the
crystal frequency, and a helper function to extract and return this
as the defined enum.
