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)
}
}

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
generated configs.

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.

The actual use of the parameter max is to keep track of PCI bus
number while recursively scanning PCI bridges or PCI-e rootports.
Neither CPU, SMBus, LPC or other static buses are involved in this
enumeration, but the way bridge operations were originally designed
forced to pass this argument thru unrelated functions.
Follow-up removes these once the function prototype gets fixed.

Use of scan_static_bus() and tree traversals is somewhat convoluted.
Start cleaning this up by assigning each path type with separate
static scan_bus() function.
For ME, SMBus and LPC paths a bus cannot expose bridges, as those would
add to the number of encountered PCI buses.

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.
