Add the I2C devices to skylake with the scan_bus handler for SMBUS
devices so that I2C-based devices can be declared in devicetree.cb
and get initialized properly during ramstage.
This does not yet provide the I2C driver, but it allows for devices
that are declared in devicetree.cb to provide ACPI tables to the OS.

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:

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) {

...
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:

struct acpi_irq irq;
};
generic.c:
void acpi_fill_ssdt_generator(struct device *dev) {
struct drivers_i2c_generic_config *config = dev->chip_info;

On apollolake the boot media layout is different in that the
traditional "BIOS" region contains another data structure with
the boot assets such as CSE firmware, PMC microcode,
CPU microcode, and boot firmware to name a few. There's also a
sort of recovery mechanism where there is a second data structure
with similar contents halfway through the "BIOS" region. This
second structure is referred as the logical boot partition 2 (LBP2),
and it's optionally employed.
Add support for writing the LBP2 to a specified FMAP region to
accommodate platforms which require it.

Add a handler for soc/intel/apollolake to return the ACPI path for
GPIOs. There are 4 GPIO "communities" on apollolake that each have a
different ACPI device so return the appropriate name for the different
communities.

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(); /bin /boot /cdrom /dev /etc /home /initrd.img /initrd.img.old /lib /lib32 /lib64 /libx32 /lost+found /media /mnt /opt /proc /root /run /sbin /srv /sys /tmp /usr /var /vmlinuz /vmlinuz.old device */
acpigen_pop_len(); /bin /boot /cdrom /dev /etc /home /initrd.img /initrd.img.old /lib /lib32 /lib64 /libx32 /lost+found /media /mnt /opt /proc /root /run /sbin /srv /sys /tmp /usr /var /vmlinuz /vmlinuz.old scope */
Will produce this ACPI code:
Scope (_SB.PCI0.I2C4) {
Device (TST0) {
Name (_HID, "TEST0000")
Name (_UID, 0)
}
}
