ec00968f08 device: i2c: Add support for I2C bus operations
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);
  }

d9af3cecae device: Add an ACPI device name and path concept to devices
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)
    }
  }

4650f5baff sconfig: Add a new generic device type
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.

16d953a460 device_romstage: Add a way to move to the next device
When trying to loop through all the devices in romstage, there was
no function to just go from one to the next.

This allows an easy way to go all the way down the chain of devices.

2a58ecde78 Add new finalize functions for devices and chips
Many chipset devices require additional configuration after
device init. It is not uncommmon for a device early in the devicetree
list to need to change a setting after a device later in the tree does
PCI init. A final function call has been added to device ops to handle
this case. It is called prior to coreboot table setup.

Another problem that is often seen is that the chipset or mainboard
need to do some final cleanup just before loading the OS. The chip
finalize has been added for this case. It is call after all coreboot
tables are setup and the payload is ready to be called.

Similar functionality could be implemented with the hardwaremain
states, but those don't fit well in the device tree function pointer
structure and should be used sparingly.

ef84401149 Add directive __SIMPLE_DEVICE__

for detection if dev->ops in the devicetree are not available
and simple device model functions need be used.

If a source file build for ramstage had __PRE_RAM__ inserted
at the beginning, the struct device would no longer match the
allocation the object had taken. This problem is fixed by
replacing such cases with explicit __SIMPLE_DEVICE__.

aad0747216 Redefine pci_bus_default_ops as function
Taking device_t as a parameter, this allows to alter the PCI config
access handlers. This is useful to add tracing of PCI config writes
for devices having problems to initialise correctly.

On older AMD platform PCI MMIO may not be able to fully configure all
PCI devices/nodes, while MMIO_SUPPORT_DEFAULT would be preferred due
to its atomic nature. So those can be forced to IO config instead.

dd4715b6a5 pnp: Implement common handling for PnP config modes
Many super i/o chips only answer to PnP requests if they are in a
configuration state (sometimes also called ext func mode). To cope with
that, the code of many chips implements its own version of our default
PnP functions like pnp_set_resource(), pnp_enable_resource() etc.

To avoid this code duplication, this patch extends our PnP device
interface with optional functions to enter and exit configuration mode.

a75561415e resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]
The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes
on a resource provided hints to the MTRR algorithm. The
IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable
space for the resource. The IORESOURCE_IGNORE_MTRR directed
the MTRR algorithm to ignore this resource as it was used reserving
RAM space.

Now that the optimizing MTRR algorithm is in place there isn't a need
for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the
MTRR code merging resources of the same cacheable type. The users
of the IORESOURCE_UMA_FB will find that the default MTRR type
calculation means there isn't a need for this flag any more.

c965076c3e resources: introduce reserved_ram_resource()
mmio_resource() was previously being used for reserving
RAM from the OS by using IORESOURCE_IGNORE_MTRR atrribute.
Instead, be more explicit for those uses with
reserved_ram_resource(). bad_ram_resource() now calls
reserved_ram_resource(). Those resources are marked as cacheable
but reserved.

The sandybridge and haswell code were relying on the implementation
fo the MTRR algorithm's interaction for reserved regions. Instead
be explicit about what ranges are MMIO reserved and what are RAM
reserved.

24d1d4b472 x86: Unify arch/io.h and arch/romcc_io.h
Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.

Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.
