Ioapic information in the devicetree was only used to set up mptables
but this generic driver was removed (ca5a793 drivers/generic/ioapic:
Drop poor implementation).
This removes the unused remainders from mainboard devicetrees.
Remove ioapic setup from sconfig.

This is all handled at runtime now, so there is no need to have the
ability to statically add lapics to the devicetree.

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.

Currently we only have runtime mechanisms to assign device operations to
a node in our devicetree (with one exception: the root device). The most
common method is to map PCI IDs to the device operations with a `struct
pci_driver`. Another accustomed way is to let a chip driver assign them.
For very common drivers, e.g. those in soc/intel/common/blocks/, the PCI
ID lists grew very large and are incredibly error-prone. Often, IDs are
missing and sometimes IDs are added almost mechanically without checking
the code for compatibility. Maintaining these lists in a central place
also reduces flexibility.
Now, for onboard devices it is actually unnecessary to assign the device
operations at runtime. We already know exactly what operations should be
assigned. And since we are using chipset devicetrees, we have a perfect
place to put that information.
This patch adds a simple mechanism to `sconfig`. It allows us to speci-
fy operations per device, e.g.
device pci 00.0 alias system_agent on
ops system_agent_ops
end
The operations are given as a C identifier. In this example, we simply
assume that a global `struct device_operations system_agent_ops` exists.

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.

Sooner or later, some board was going to need extra FW_CONFIG bits for
a field that was already in production, so this patch adds support for
adding extra (unused) bits to a field.
The extra are appended via a syntax like:
`field FIELD_NAME START0 END0 | START1 END1 | START2 END2 ...`
and the suffixed bits are all treated as if they are contiguous when
defining option values.

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 works for both the baseboard devicetree.cb as well as variant
overridetree.cb.

Rarely, the driver of one device needs to know about another device
that can be anywhere in the device hierarchy. Current applications
boil down to EEPROMs that store information that is consumed by some
code (e.g. MAC address).
The idea is to give device nodes in the `devicetree.cb` an alias that
can later be used to link it to a device driver's `config` structure.
The driver has to declare a field of type `struct device *`, e.g.
struct some_chip_driver_config {
DEVTREE_CONST struct device *needed_eeprom;
};
In the devicetree, the referenced device gets an alias, e.g.
device i2c 0x50 alias my_eeprom on end
The author of the devicetree is free to choose any alias name that
is unique in the devicetree. Later, when configuring the driver the
alias can be used to link the device with the field of a driver's
config:
chip some/chip/driver
use my_eeprom as needed_eeprom
end
Override devices can add an alias if it does not exist, but cannot
change the alias for a device that already exists.
Alias names are checked for conflicts both in the base tree and in the
override tree.
References are resolved after the tree is parsed so aliases and
references do not need to be in a specific order in the tree.

This change adds support to sconfig for generating the firmware
configuration field and option definitions in devicetree.cb.
In addition these fields and options can be used to probe for a device
and have that device be disabled if it is not found at boot time.
New tokens:
fw_config: top level token, table can be defined before chips
field: define field in the mask with the start and end bits
option: define option in a field with the value of the field
probe: indicate that a device should probe by field and option
Example:
fw_config
field FEATURE 0 0
option DISABLE 0
option ENABLE 1
end
end
chip drivers/generic/feature
device generic 0 on
probe FEATURE ENABLE
end
end
Variants can add new fields and add new options to existing fields in
overridetree.cb but cannot redefine an existing option.
Devices can have multiple probe tokens, and the device will be considered
to be found if any of them return true.
The output from defining this field are:
1) the various fields and options will be added as macro constants to
static.h and can be used by fw_config for probing.
2) the probe entries will result in a list of fields/options to probe
that is added to the resulting struct device and handled by coreboot.

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,

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

Add the new field 'smbios_slot_desc', which takes 2 to 4 arguments.
The field is valid for PCI devices and only compiled if SMBIOS table
generation is enabled.
smbios_slot_desc arguments:
1. slot type
2. slot lenth
3. slot designation (optional)
4. slot data width (optional)
Example:
device pci 1c.1 on
smbios_slot_desc "21" "3" "MINI-PCI-FULL" "8"

For devices supporting both Linux and Windows, we may find some ACPI
devices that only need drivers in Linux and should not even be shown in
Windows Device Manager UI.
The new 'hidden' keyword in device tree 'device' statement allows
devices sharing same driver to call acpi_gen_writeSTA with different

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
|
RootHub
| |
USB2[0] USB3[2]

end

end
end
end

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.

Currently you cannot assign a string to a register in devicetree because
the quotes are removed when parsing and the literal is assigned directly.
Add a parse option for two double-quotation marks to indicate a string
and return a quoted literal that can be assigned to a register with a
'const char *' type.
Example:
chip drivers/i2c/generic
register "hid" = ""INT343B""
register "uid" = "1"
device i2c 15 on end

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.

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.

This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.
Syntax in devicetree.cb:
ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>
The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

If the user wants to have this ID inherited to all subdevices/functions,
he can add 'inherit', like in the following example:

subsystemid dead beef inherit
end
If the user don't want to inherit a Subsystem for a single device, he can
