Intel WiFi devices that support wake-on-wifi need to declare a Power
Resource for this wake pin. Typically this has been done with a
static declaration in the DSDT for each mainboard. By adding it to
the existing intel/wifi driver it can be done based on a
configuration register in the devicetree.
Additionally the WiFi regulatory domain can be set in the SSDT
directly instead of needing to use NVS to pass the value to the DSDT.
Also add device IDs for Wilkins Peak 2 and Stone Peak 2 devices that
are found on Chromebooks, and clean up a long line and some comment
formatting.
This was tested by booting on an HP Chromebook 13 device and comparing
that the output in the SSDT matches what used to be in the DSDT. The
WRDD value is read from VPD, if present, not from devicetree.cb.
Additionally the case where CONFIG_DRIVERS_INTEL_WIFI is enabled but
the wifi device is not described in devicetree.cb is tested to ensure
it still generates the AML but does not include the _PRW wake pin.
Example:
devicetree.cb:
device pci 1c.0 on
chip drivers/intel/wifi
register "wake" = "GPE0_DW0_16"
device pci 00.0 on end
end
end

Add a universal hybrid graphics driver compatible with
all supported lenovo devices.
Hybrid graphics allows to connect the display panel to
either of one GPUs.
As there are only two GPUs one GPIO needs to be toggled.
In case the discrete GPU is activated the panel is routed to it.
On deactivation the panel is routed to the integrated
GPU.
On lenovo laptops the dGPU is always connected to PEG10 and it is
save to disable the PEG slot on dGPU deactivation.
Use common gpio.c for southbridge I82801IX.
Tested on Lenovo T520 using Nvidia NVS 5200m.
Removed Lenovo T430s from the list of supported devices,
as the T430s only supports "muxless Optimus".

The Nuvoton NAU8825 audio codec is an I2C device that has a number of

This sample configuration in devicetree:

The VBOOT_OPROM_MATTERS configuration option signals to vboot that the
board can skip display initialization in the normal boot path. It's name
is a left-over from a time when this could only happen by avoiding to
load the VGA option ROM on x86 devices, but nowadays we have other
boards that can skip their native display initialization paths too, and
the effect to vboot is the same. (Really, we should rename oprom_matters
and oprom_loaded to display_skippable and display_initialized or
something, but I don't think that's worth the amount of repositories
this would need to touch.)
The only effect this still has in today's vboot is to reboot and
explicitly request display initialization for EC software sync on
VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still,
the vboot flag just declares the capability (for skipping display init),
and it should be set correctly regardless of whether that actually makes
a difference on a given platform (right now). This patch updates all
boards/SoCs that have a conditional path based on
display_init_required() accordingly.

Add a PCI driver for the skylake SD card device and have it generate

This sets up a card detect GPIO configuration that will trigger an

SD controller from D3 state.
The GpioInt() entry is bound to the cd-gpio device property which will

The recent ACPI specification extensions have formally defined a
method for describing device information with a key=value format that
is modeled after the Devicetree/DTS format using a special crafted
object named _DSD with a specific UUID for this format.
There are three defined Device Property types: Integers, Strings, and
References. It is also possible to have arrays of these properties
under one key=value pair. Strings and References are both represented
as character arrays but result in different generated ACPI OpCodes.
Various helpers are provided for writing the Device Property header
(to fill in the object name and UUID) and footer (to fill in the
property count and device length values) as well as for writing the
different Device Property types. A specific helper is provided for
writing the defined GPIO binding Device Property that is used to allow
GPIOs to be referred to by name rather than resource index.
This is all documented in the _DSD Device Properties UUID document:
http://uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf
This will be used by device drivers to provide device properties that
are consumed by the operating system. Devicetree bindings are often
described in the linux kernel at Documentation/devicetree/bindings/
A sample driver here has an input GPIO that it needs to describe to
the kernel driver:
chip.h:
struct drivers_generic_sample_config {
struct acpi_gpio mode_gpio;
};
sample.c:
static void acpi_fill_ssdt_generator(struct device *dev) {
struct drivers_generic_sample_config *config = dev->chip_info;
const char *path = acpi_device_path(dev);
...
acpi_device_write_gpio(&config->mode_gpio);
...
acpi_dp_write_header();
acpi_dp_write_gpio("mode-gpio", path, 0, 0, 0);
acpi_dp_write_footer();
...
}
devicetree.cb:

end

Add definitions to describe GPIOs in generated ACPI objects and a
method to write a GpioIo() or GpioInt() descriptor to the SSDT.
ACPI GPIOs have many possible configuration options and a structure
is created to describe it accurately in ACPI terms. There are many
shared descriptor fields between GpioIo() and GpioInt() so the same
function can write both types.
GpioInt shares many properties with ACPI Interrupts and the same types
are re-used here where possible. One addition is that GpioInt can be
configured to trigger on both low and high edge transitions.
One descriptor can describe multiple GPIO pins (limited to 8 in this
implementation) that all share configuration and controller and are
used by the same device scope.
Accurately referring to the GPIO controller that this pin is connected
to requires the SoC/board to implement a function handler for
acpi_gpio_path(), or for the caller to provide this directly as a
string in the acpi_gpio->reference variable.
This will get used by device drivers to describe their resources in
the SSDT. Here is a sample for a Maxim 98357A I2S codec which has a
GPIO for power and channel selection called "sdmode".
chip.h:
struct drivers_generic_max98357a_config {
struct acpi_gpio sdmode_gpio;
};
max98357a.c:
void acpi_fill_ssdt_generator(struct device *dev) {
struct drivers_generic_max98357a_config *config = dev->chip_info;
...
acpi_device_write_gpio(&config->sdmode_gpio);
...

Add definitions for ACPI device extended interrupts and a method to
write an Interrupt() descriptor to the SSDT output stream.
Interrupts are often tied together with other resources and some
configuration items are shared (though not always compatibly) with
other constructs like GPIOs and GPEs.
These will get used by device drivers to write _CRS sections for
devices into the SSDT. One usage is to include a "struct acpi_irq"
inside a config struct for a device so it can be initialized based
on settings in devicetree.
Example usage:
chip.h:
struct drivers_i2c_generic_config {
struct acpi_irq irq;
};
generic.c:
void acpi_fill_ssdt_generator(struct device *dev) {
struct drivers_i2c_generic_config *config = dev->chip_info;
...
acpi_device_write_interrupt(&config->irq);
...
}
devicetree.cb:
device pci 15.0 on
chip drivers/i2c/generic
register "irq" = "IRQ_EDGE_LOW(GPP_E7_IRQ)"
device i2c 10 on end
end
end

Chrome OS builds always have some inherent differences to "standard"
libpayload configurations: they don't want to use curses or things like
storage drivers, they always use the coreboot framebuffer and USB, etc.
This patch reintroduces CONFIG_LP_CHROMEOS as an option that only
affects Kconfig defaults. This allows Chrome OS builds to select most of
what they need in one go and reduces board-specific .config files to
only the options that are really specific to that board.
Also restricts the 8250_SERIAL_CONSOLE Kconfig to only default to yes on
x86 boards, which probably makes sense for all of libpayload (some but
far from all ARM boards use 8250-compatible UARTs, and we should
probably not default a platform option unless it's going to be correct
with very high probability).

Currently every non-x86 platform supported by libpayload needs to
provide its own timer driver. Most of the ones we have accumulated there
look almost identical: For the frequency, return a preset constant. For
the value, read a 32-bit register, possibly read another 32-bit register
and shift+OR it with the previous one, then return that.
Let's replace this with a single .c file that can easily handle all of
those cases. Menuconfig convenience can still be maintained by providing
several presets that select different defaults for the driver's
configuration options (register address(es) and frequency).
Removes an "enabled" check from Samsung MCT driver since coreboot always
unconditionally enables that timer anyway.
