Add a function to return the PCI domain device for the specified
device. On multi PCI domain platforms this function allows to
determine which domain and thus which socket the PCI device
belongs to.

Add initial support for multiple PCI segment groups. Instead of
modifying secondary in the bus struct introduce a new segment_group
struct element and keep existing common code.
Since all platforms currently only use 1 segment this is not a
functional change. On platforms that support more than 1 segment the
segment has to be set when creating the PCI domain.

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.

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.

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.

The `IORESOURCE_ABOVE_4G` flag was only explicitly set for our dummy

including real ones. Let's make that explicit, so future changes to the
allocator can't break this rule.

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.

When a chipset or mainboard devicetree doesn't have any LAPIC devices in
its CPU cluster, not only the LAPIC device, but also the link/bus
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 3c0ecd57c174b7391c66d22406effe18ce570cac (soc/intel/common/cpu:
Handle non-zero BSP APIC ID in init_cpus) and
commit ba936ce5db819d5ecb34e83a998b2390ecbdc4b9 (soc/intel/denverton_ns:

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.

is enabled based on given device function number. This
function internally called is_dev_enabled() to check
device state.

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
perform their own separate probing.

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.

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

This CL has changes that allow us to enable a configurable
ramstage, and one change that allows us to minimize PCI
scanning. Minimal scanning is a frequently requested feature.
To enable it, we add two new variables to src/Kconfig
CONFIGURABLE_RAMSTAGE
is the overall variable controlling other options for minimizing the
ramstage.
MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal
PCI scanning.
Some devices must be scanned in all cases, such as 0:0.0.
To indicate which devices we must scan, we add a new mandatory
keyword to sconfig
It is used in place of on, off, or hidden, and indicates
a device is enabled and mandatory. Mandatory
devices are always scanned. When MINIMAL_PCI_SCANNING is enabled,
ONLY mandatory devices are scanned.
We further add support in src/device/pci_device.c to manage
both MINIMAL_PCI_SCANNING and mandatory devices.
Finally, to show how this works in practice, we add mandatory
keywords to 3 devices on the qemu-q35.

This change adds support for allocating resources for PCI express hotplug
bridges when PCIEXP_HOTPLUG is selected. By default, this will add 32 PCI
subordinate numbers (buses), 256 MiB of prefetchable memory, 8 MiB of
non-prefetchable memory, and 8 KiB of I/O space to any device with the
PCI_EXP_SLTCAP_HPC bit set in the PCI_EXP_SLTCAP register, which
indicates hot-plugging capability. The resource allocation is configurable,
please see the PCIEXP_HOTPLUG_* variables in src/device/Kconfig.
In order to support the allocation of hotplugged PCI buses, a new field
is added to struct device called hotplug_buses. This is defaulted to
zero, but when set, it adds the hotplug_buses value to the subordinate
value of the PCI bridge. This allows devices to be plugged in and
unplugged after boot.
This code was tested on the System76 Darter Pro (darp6). Before this
change, there are not enough resources allocated to the Thunderbolt
PCI bridge to allow plugging in new devices after boot. This can be
worked around in the Linux kernel by passing a boot param such as:
pci=assign-busses,hpbussize=32,realloc
This change makes it possible to use Thunderbolt hotplugging without
kernel parameters, and attempts to match closely what our motherboard
manufacturer's firmware does by default.

So, the PCI to PCI bridge specification had a pitfall for us:
Originally, when decoding i/o ports for legacy VGA cycles, bridges
should only consider the 10 least significant bits of the port address.
This means all VGA registers were aliased every 1024 ports!
e.g. 0x3b0 was also decoded as 0x7b0, 0xbb0 etc.
However, it seems, we never reserved the aliased ports, resulting in
silent conflicts we preallocated resources. We neither use much
external VGA nor many i/o ports these days, so nobody noticed.
To avoid this mess, a bridge control bit (VGA16) was introduced in
2003 to enable decoding of 16-bit port addresses. As older systems
seem rather safe and well tested, and newer systems should support
this bit, we'll use it if possible and only warn if not.
With old (AGP era) hardware one will likely encounter a warning like
this:
found VGA at PCI: 06:00.0
A bridge on the path doesn't support 16-bit VGA decoding!
This is not generally fatal, but makes unnoticed resource conflicts
more likely.

from nb/amd/amdfam10 was chosen to be kept, since it contains several

Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.
A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.
The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.
For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:
xHCI
