Doing PCI config operations via MMIO window by default is a
requirement, if supported by the platform. This means chipset
or CPU code must enable MMCONF operations early in bootblock
already, or before platform-specific romstage entry.
Platforms are allowed to have NO_MMCONF_SUPPORT only in the
case it is actually not implemented in the silicon.

Some PCI-e capability registers are located starting from
0x100, these are not accessible using the conventional
PCI IO config operations at 0xcf8/0xcfc, unless PCI_CFG_EXT_IO
was selected.
Thus any feature that calls pciexp_find_extended_cap()
depends on either MMCONF_SUPPORT_DEFAULT or PCI_CFG_EXT_IO
being enabled on the platform.
In theory there can be system without MMCONF_SUPPORT, but
with complete PCI Express configuration space available
using PCI_CFG_EXT_IO. Do not use explicit PCI MMCONF
operations here, but rely on the default PCI access
method to be able to access all of the configuration space.
While at it, convert to IS_ENABLED() everywhere in the source
and organize Kconfig file better.

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);
}

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
