702365e186 include/device/device: drop unused alignment defines
The resource allocator's setup_resource_ranges will make sure that the
memory resources are 4KiB-aligned. The resource allocator doesn't
enforce any alignment requirements on IO regions.

a9dd3c3fae lib/version: Move board identification strings
These strings are now only expanded in lib/identity.c.

This improves ccache hit rates slightly, as one built object file
lib/version.o is used for all variants of a board. Also one built
object file lib/identity.o can become a ccache hit for successive
builds of a variant, while the commit hash changes.

e111de0752 lib: set up specific purpose memory as LB_MEM_SOFT_RESERVED
CXL (Compute Express Link) [1] is a cache-coherent interconnect
standard for processors, memory expansion and accelerators.

CXL memory is provided through CXL device which is connected
through CXL/PCIe link, while regular system memory is provided
through DIMMs plugged into DIMM slots which are connected to
memory controllers of processor.

With CXL memory, the server's memory capacity is increased.
CXL memory is in its own NUMA domain, with longer latency
and added bandwidth, comparing to regular system memory.

Host firmware may present CXL memory as specific purpose memory.
Linux kernel dax driver provides direct access to such differentiated
memory. In particular, hmem dax driver provides direct access to
specific purpose memory.

Specific purpose memory needs to be represented in e820 table as
soft reserved, as described in [2].

Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory)
resource that needs to be soft reserved.

Add soft_reserved_ram_resource macro to allow soc/mb code to add
memory resource as soft reserved.

20d25779c8 device/pci_device.c: Add way to limit max bus numbers
By default this limits PCI buses to CONFIG_MMCONF_BUS_NUMBER.
Some platforms have multiple PCI root busses (e.g. xeon_sp), where bus
numbers are limited. This provides a basic check. On some platforms it
looks like programming 0xff to the subordinate bus number confuses and
hangs the hardware.

67f63e768d src/device + util/sconfig: Introduce new device 'mdio'
This patch extends the available device paths with a new device 'mdio'.
MDIO is the 'Management Data Input/Output' called interface which is
used to access an Ethernet PHY behind a MAC to change settings. The real
payload data path is not handled by this interface.

To address the PHY correctly on the MDIO bus, there is a 5 bit address
needed, which often can be configured via pins on the mainboard.
Therefore, the new introduced device has an 'addr' field to define its
address. If one wants to use a MDIO device in devicetree, the syntax is
straight forward (example):
	device mdio 0x2 on end

As the MDIO interface is driven by the MAC, most likely this MDIO device
will be hooked in as a child device of the (PCI attached) MAC device.

With the new introduced ops_mdio a new interface is added to provide an
API for read and write access over MDIO.

Files that were written specifically for coreboot and don't have license

Files that were sourced from Linux are similarly GPL-2.0-only.

The cpu/power files were committed with source that was licensed as
GPL-2.0-or-later, so presumably that's the license for that entire
commit.

437da71d0a SMBIOS/SCONFIG: Allow devtree-defined Type 41 entries
Introduce the `smbios_dev_info` devicetree keyword to specify the
instance ID and RefDes (Reference Designation) of onboard devices.

Example syntax:

 device pci 1c.0 on	# PCIe Port #1
 	device pci 00.0 on
 		smbios_dev_info 6
 	end
 end
 device pci 1c.1 on	# PCIe Port #2
 	device pci 00.0 on
 		smbios_dev_info 42 "PCIe-PCI Time Machine"
 	end
 end

The `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` Kconfig option enables using
this syntax to control the generated Type 41 entries. When this option
is enabled, Type 41 entries are only autogenerated for devices with a
defined instance ID. This avoids having to keep track of which instance
IDs have been used for every device class.

Using `smbios_dev_info` when `SMBIOS_TYPE41_PROVIDED_BY_DEVTREE` is not
enabled will result in a build-time error, as the syntax is meaningless
in this case. This is done with preprocessor guards around the Type 41
members in `struct device` and the code which uses the guarded members.
Although the preprocessor usage isn't particularly elegant, adjusting
the devicetree syntax and/or grammar depending on a Kconfig option is
probably even worse.

60e9114c62 include/device: ensure valid link/bus is passed to mp_cpu_bus_init
When a chipset or mainboard devicetree doesn't have any LAPIC devices in

between the CPU cluster device and the LAPIC devices will be missing and
the CPU cluster's dev->link_list will be NULL. This patch handles this
case in the common code like
commit 3c0ecd57c1 (soc/intel/common/cpu:
Handle non-zero BSP APIC ID in init_cpus) and
commit ba936ce5db (soc/intel/denverton_ns:
Ensure CPU device has a valid link) already did in the common Intel SoC
and the Denverton code. With this change all CPUs and SoC that use the
common mp_cpu_bus_init as init function in the CPU cluster's device
operations struct won't require having at least one LAPIC device in the
chipset or mainboard device tree.

7f6ae79280 device: Consider fw_config probing in is_dev_enabled()
With the introduction of fw_config support in coreboot, it is possible
for mainboards to control the state of a device (on/off) in ramstage
using fw_config probe conditions. However, the device tree in
immutable in all other stages and hence `is_dev_enabled()` does not
really reflect the true state as in ramstage.

This change adds a call to `fw_config_probe_dev()` in
`is_dev_enabled()` when device tree is immutable (by checking
DEVTREE_EARLY) to first check if device is disabled because of device
probe conditions. If so, then it reports device as being
disabled. Else, dev->enabled is used to report the device state.

This allows early stages (bootblock, romstage) to use
`is_dev_enabled()` to get the true state of the device by taking probe
conditions into account and eliminates the need for each caller to

This change updates the definition of config_of_soc() to a macro that
expands to __pci_0_00_0_config instead of accessing the config

dbb667ac08 device + util/sconfig: introduce new device gpio
Introduce a new device `gpio` that is going to be used for generic
abstraction of gpio operations in the devicetree.

The general idea behind this is that every chip can have gpios that
shall be accessible in a very generic way by any driver through the
devicetree.

The chip that implements the chip-specific gpio operations has to assign
them to the generic device operations struct, which then gets assigned
to the gpio device during device probing. See CB:48583 for how this gets
done for the SoCs using intelblocks/gpio.

The gpio device then can be added to the devicetree with an alias name
like in the following example:

  chip soc/whateverlake
    device gpio 0 alias soc_gpio on end
    ...
  end

Any driver that requires access to this gpio device needs to have a
device pointer (or multiple) and an option for specifying the gpio to be
used in its chip config like this:

  struct drivers_ipmi_config {
    ...
    DEVTREE_CONST struct device *gpio_dev;
    u16 post_complete_gpio;
    ...
  };

The device `soc_gpio` can then be linked to the chip driver's `gpio_dev`
above by using the syntax `use ... as ...`, which was introduced in
commit 8e1ea52:

  chip drivers/ipmi
    use soc_gpio as gpio_dev
    register "bmc_jumper_gpio" = "GPP_D22"
    ...
  end

The IPMI driver can then use the generic gpio operations without any
knowlege of the chip's specifics:

  unsigned int gpio_val;
  const struct gpio_operations *gpio_ops;
  gpio_ops = dev_get_gpio_ops(conf->gpio_dev);
  gpio_val = gpio_ops->get(conf->bmc_jumper_gpio);

For a full example have a look at CB:48096 and CB:48095.

This change adds the new device type to sconfig and adds generic gpio
operations to the `device_operations` struct. Also, a helper for getting
the gpio operations from a device after checking them for NULL pointers
gets added.

Successfully tested on Supermicro X11SSM-F with CB:48097, X11SSH-TF with
CB:48711 and OCP DeltaLake with CB:48672.

36e6c6f8d2 fw_config: Add firmware configuration interface
This change introduces a new top-level interface for interacting with a
bitmask providing firmware configuration information.

This is motivated by Chromebook mainboards that need to support multiple
different configurations at runtime with the same BIOS.  In these
devices the Embedded Controller provides a bitmask that can be broken
down into different fields and each field can then be broken down into
different options.

The firmware configuration value could also be stored in CBFS and this
interface will look in CBFS first to allow the Embedded Controller value
to be overridden.

The firmware configuration interface is intended to easily integrate
into devicetree.cb and lead to less code duplication for new mainboards
that make use of this feature.

BUG=b:147462631
TEST=this provides a new interface that is tested in subsequent commits
