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
loading the VGA option ROM on x86 devices. Now 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.

Support the common Intel LPSS I2C driver for the 6 I2C bus controllers
that are present on the Skylake-LP PCH with a 120 mHz clock. The
required lpss_i2c_base_address() method is implemented separately for
verstage/romstage and ramstage environments.
This provides methods to convert to and from "struct device" and the
I2C controller bus number for that device. These are used to provide
support for the "I2C Bus Operations" that are present in the coreboot
devicetree.
To support the I2C controller before ramstage an early init function
is provided to do minimal initializaiton of the PCI device and assign
a temporary base address for use before memory. The final base
address is assigned during device enumeration and used during ramstage.
Because it is usually not necessary to enable I2C controllers before
ramstage a config register for the devicetree is provided to perform
early initialization of this controller. In addition the bus speed
can be set in the devicetree and that speed will be applied when the
device is initialized. If not provided the default speed is set to
I2C_SPEED_FAST.
This was tested with the google/chell mainboard by reading and writing
from the trackpad and codec devices during both verstage and ramstage.

Add a generic LPSS I2C driver for Intel SOCs that use the Synopsys
DesignWare I2C block and have a similar configuration of that block.
This driver is ported from the Chromium depthcharge project where it
was ported from U-Boot originally, though it looks very different now.
From depthcharge it has been modified to fit into the coreboot I2C
driver model with platform_i2c_transfer() and use coreboot semantics
throughout including the stopwatch API for timeouts.
In order for this shared driver to work the SOC must:
1) Define CONFIG_SOC_INTEL_COMMON_LPSS_I2C_CLOCK_MHZ to set the clock
speed that the I2C controller core is running at.
2) Define the lpss_i2c_base_address() function to return the base
address for the specified bus. This could be either done by looking
up the PCI device or a static table if the controllers are not PCI
devices and just have a static base address.
The driver is usable in verstage/romstage/ramstage, though it does
require early initialization of the controller to set a temporary base
address if it is used outside of ramstage.
This has been tested on Broadwell and Skylake SOCs in both pre-RAM and
ramstage environments by reading and writing both single bytes across
multiple segments as well as large blocks of data at once and with
different configured bus speeds.
While it does need specific configuration for each SOC this driver
should be able to work on all Intel SOCs currently in src/soc/intel.

In order to support doing bus operations on an I2C device that is
described in the devicetree there needs to be some linkage of the
device and the existing opaque I2C controller bus number.
This is provided in a similar fashion to the existing SMBUS operations
but modified to fit within the existing I2C infrastructure.
Variants of the existing I2C helper functions are provided that will
obtain the bus number that corresponds to this device by looking for
the SOC-provided I2C bus operation structure to provide a function
that will make that translation.
For example an SOC using a PCI I2C controller at 0:15.0 could use:
soc/intel/.../i2c.c:
static int i2c_dev_to_bus(struct device *dev)
{
if (dev->path.pci.devfn == PCI_DEVFN(0x15, 0))
return 0;
return -1;
}
static struct i2c_bus_operation i2c_bus_ops = {
.dev_to_bus = &i2c_dev_to_bus
}
static struct device_operations i2c_dev_ops = {
.ops_i2c_bus = &i2c_bus_ops
...
}
With an I2C device on that bus at address 0x1a described in the tree:
devicetree.cb:
device pci 15.0 on # I2C0
chip drivers/i2c/sample
device i2c 1a.0 on end
end
end
That driver can then do I2C transactions with the device object
without needing to know that the SOC-specific bus number that this
I2C device lives on is "0".
For example it could read a version value from register address 0
with a byte transaction:
drivers/i2c/sample/sample.c:
static void i2c_sample_enable(struct device *dev)
{
uint8_t ver;
if (!i2c_dev_readb(dev, 0x00, &ver))
printk(BIOS_INFO, "I2C %s version 0x02x\n", dev_path(dev), ver);
}

Previous FSP implementations in coreboot have included FspUpdVpd.h
directly, along with with efi headers. Instead of taking that
approach in FSP 2.0, we provide a semantic patch that, with minimal
modifications, makes FspUpdVpd.h easier to include in coreboot, and
eliminates reliance on external headers and definitions.

- when jack is inserted it is chosen instead of internal speaker

This patch adds functions to init the display. To set up the display,
initialize the eDP and read the EDID. Based on these, we then
set the clock for VOP, and finally enable VOP and backlight.
For a mainboard, it should set the vop_id, vop_mode and
framebuffer_bits_per_pixel in devicetree.cb.
For VOP_MODE_AUTO_DETECT, it will try eDP first and then
HDMI (which is not supported yet).
EDIT: Updated Makefile to only build in new files if
MAINBOARD_DO_NATIVE_VGA_INIT is enabled. All of these

The Maxim Integrated 98357A codec is an I2S slave device that has no
control channel for configuration and instead provides a GPIO that is
used for channel selection and power down. This means it does not fit
into a bus hierarchy easily and is instead represented as a generic
device and found with a static bus scan using the devicetree.
This driver provides configuration options for passing the "sdmode" GPIO
descriptor as well as a second option for "sdmode delay" which can
configure the timing of the sdmode toggling in relation to the I2S
channel output.
In addition an GPIO can be provided to indicate to the driver whether
this device is present or not. This can be used for board designs that
may have different codec possibilities that are selected by HW strap.
Sample usage for this device driver:
device pci 1f.3 on
chip drivers/generic/max98357a
register "sdmode_gpio" = "ACPI_GPIO_OUTPUT(GPP_C6)"
register "sdmode_delay" = "100"
device generic 0 on end
end
end
Will result in the following code in the SSDT:
Scope (\_SB.PCI0.HDAS) {
Device (MAXM) {
Name (_HID, "MX98357A")

This adds a generic I2C driver that can be described in the devicetree
and used to generate ACPI objects in the SSDT based on the information
provided in the config registers.
The I2C bus can be configured and the device can provide an interrupt and
wake capability to the OS. A configuration option allows for a GPIO to
be provided that will be checked to determine if the device is preset on
the board before including it in the generated SSDT.
The driver is generic enough to be used for basic I2C devices that do
not have special configuration needs such as touchpads, touchscreens,
sensors, some audio codec/amplifiers, etc.
Sample usage for a touchpad device:
device pci 15.1 on
chip drivers/i2c/generic
register "hid" = ""ELAN0000""
register "desc" = "ELAN Touchpad"
register "irq" = "IRQ_EDGE_LOW(GPP_B3_IRQ)"
register "wake" = "GPE0_DW0_05"
device i2c 15.0 on end
end
end
Will result in the following code in the SSDT:
Scope (\_SB.PCI0.I2C1) {
Device (D015) {
Name (_HID, "ELAN0000")
Name (_UID, 0)
Name (_S0W, 4)

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

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

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 {

...
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();
...
}

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;

Add a handler for the Intel Skylake SOC to return the ACPI path for
GPIOs. Since all GPIOs are handled by the same controller they all
have the same ACPI path and this is a simple handler that just returns
a pointer to the GPIO device that is defined in the DSDT.

Add a new function "gpio_acpi_path()" that can be implemented by
SoC/board code to provide a mapping from a "gpio_t" pin to a
controller by returning the ACPI path for the controller that owns
this particular GPIO.
This is implemented separately from the "acpi_name" handler as many
SOCs do not have a specific device that handles GPIOs (or may have
many devices and the only way to know which is the opaque gpio_t)
and the current GPIO library does not have any association with the
device tree.
If not implemented (many SoCs do not implement the GPIO library
abstraction at all in coreboot) then the default handler will return
NULL and the caller knows it cannot determine this reliably.

Add a global ACPI device name handler for the Skylake SOC that will
translate skylake device paths into an ACPI path that matches the
device objects delcared in the DSDT at soc/intel/skylake/acpi/*.
The skylake implementation uses a global acpi_name handler for the
SOC and it is not necessary to add a function to every device.
This function is used by device drivers calling acpi_device_name()
and acpi_device_path() to generate ACPI AML in the SSDT.

Add a function to "struct device_operations" to return the ACPI name
for the device, and helper functions to find this name (either from
the device or its parent) and to build a fully qualified ACPI path
from the root device.
This addition will allow device drivers to generate their ACPI AML in
the SSDT at boot, with customization supplied by devicetree.cb,
instead of needing custom DSDT ASL for every mainboard.
The root device acpi_name is defined as "\\_SB" and is used to start
the path when building a fully qualified name.
This requires SOC support to provide handlers for returning the ACPI
name for devices that it owns, and those names must match the objects
declared in the DSDT. The handler can be done either in each device
driver or with a global handler for the entire SOC.
Simplified example of how this can be used for an i2c device declared
in devicetree.cb with:
chip soc/intel/skylake # "\_SB" (from root device)
device domain 0 on # "PCI0"
device pci 19.2 on # "I2C4"
chip drivers/i2c/test0
device i2c 1a.0 on end # "TST0"
end
end
end
end
And basic SSDT generating code in the device driver:
acpigen_write_scope(acpi_device_scope(dev));
acpigen_write_device(acpi_device_name(dev));
acpigen_write_string("_HID", "TEST0000");
acpigen_write_byte("_UID", 0);
acpigen_pop_len(); /* device */
acpigen_pop_len(); /* scope */
Will produce this ACPI code:
Scope (\_SB.PCI0.I2C4) {
Device (TST0) {
Name (_HID, "TEST0000")
Name (_UID, 0)
}
}

timestamp_cache_get() would call timestamp_cache_init() whenever it
found a timestamp cache in the TIMESTAMP_CACHE_UNINITIALIZED state.
That means that timestamp_cache_get() will never reurn a cache in the
uninitialized state.
However, timestamp_init() checks against the uninitialized state, as
it does not expect timestamp_cache_get() to perform any initialization.
As a result, the conditional branch can never be reached.
Simply remove the timestamp_cache_init() call from timestamp_cache_get().

timestamp.c was not included in bootblock and postcar. This means that
these two stages would use the weak implementation in lib/timestamp.c
instead of the arch-specific implementation based on rdtsc.
This resulted in using timer_monotonic_get() which resets the
timestamps from 0. timer_monotonic_get() only provides per-stage
incrementing semantics on x86 because lapic implementation has
counting down values. A globally incrementing counter like rdtsc
provides the semantics like every other non-x86.
On the test configuration, the weak implementation of timestamp_get()
returned zero, resulting in wrong timestamps coming from the bootblock,
while romstage and ramstage used the arch implementation and returned
correct timestamps.
This is a great example of why weak functions are dangerous, and how
easy it is to miss subtle yet strong interactions between subsystems
and the coreboot buildsystem.

to use a specific resource for temporary memory. As result coreboot
is forced to use CAR layout dictated by default FSP-M configuration.
Change CAR size to 1MiB, link romstage at such CAR address so it
doesn't overlap with FSP-M's default heap/stack.

Add support for a basic generic device in the devicetree to bind to a
device that does not have a specific bus, but may need to be described
in tables for the operating system. For instance some chips may have
various GPIO connections that need described but do not fall under any
other device.
In order to support this export the basic 'scan_static_bus()' that can
be used in a device_operations->scan_bus() method to scan for the generic
devices.
It has been possible to get a semi-generic device by using a fake PNP
device, but that isn't really appropriate for many devices.
Also Re-generate the shipped files for sconfig. Use flex 2.6.0 to avoid
everything being rewritten. Clean up the local paths that leak into the

as one can have FMAP without a CHROMEOS build. As a result, always
search FMAP first before falling back on CBFS for locating the MRC
cache region.
The old logic where CHROMEOS builds would fail when RW_MRC_CACHE was
not found is preserved, such that behavior does not change.
