Martin Roth 8324fe9211 drivers: Add SPDX license headers to Makefiles
To help identify the licenses of the various files contained in the
coreboot source, we've added SPDX headers to the top of all of the
.c and .h files. This extends that practice to Makefiles.

Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.

This patch adds the GPL V2 license identifier to the top of all
makefiles in the drivers directory that don't already have an SPDX
license line at the top.

Reka Norman 93928194c4 drivers/wifi/generic: Revert changes to generate missing SSDT for PCIe
wifi

This reverts commit 5e6fd360de.

On nereid, the SSDT entry for the PCIe wifi device is missing, causing
wake-on-WLAN not to work since the _PRW is missing.

It seems like when commit 5e6fd360de changed the SSDT generation logic
for CNVi and PCIe wifi, it broke the PCIe case. `wifi_pcie_ops` are
never assigned to any device, so
`parent && parent->ops == &wifi_pcie_ops` always returns false, and the
`wifi_cnvi_ops` are used even for PCIe devices.

Undo the changes in that CL. This allows both the CNVi and PCIe cases to
work. That CL was meant to fix an issue with the CNVi _PRW containing
garbage, but I can't reproduce this when the change is undone.

It was also meant to fix the following error on CNVi devices, but I
don't see any errors with this change:
[ERROR]  NONE missing set_resources

BUB=b:233325709
TEST=On both nivviks (CNVi) and nereid (PCIe), check that the SSDT
contains the correct wifi device entries (below), including a _PRW
containing the correct GPE, and check that wake-on-WLAN works.

nivviks:
```

    {
        Name (_PRW, Package (0x02)  // _PRW: Power Resources for Wake
        {

        {

    }
```

coreboot needs to propagate the CnviDdrRfim value info of the feature

Julius Werner e9665959ed treewide: Remove "ERROR: "/"WARN: " prefixes from log messages
Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.

This patch was created by running

  find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'

and doing some cursory review/cleanup on the result. Then doing the same

Angel Pons 6a73b2466f SMBIOS: Allow skipping default SMBIOS generation
The call to the `get_smbios_data` device operation is followed by
calls to unconditional default functions, which lacks flexibility.
Instead, have devices that implement `get_smbios_data` call these
default functions as needed.

Most `get_smbios_data` implementations are in mainboard code, and are
bound to the root device. The default functions only operate with PCI
devices because of the `dev->path.type != DEVICE_PATH_PCI` checks, so
calling these functions for non-PCI devices is unnecessary. QEMU also
implements `get_smbios_data` but binds it to the domain device, which
isn't PCI either.

This patch modifies it to extend support for intel wifi 6 and wifi 6e

Furquan Shaikh 6017abbc2c drivers/wifi/generic: Split wifi_generic_fill_ssdt into two functions
This change splits `wifi_generic_fill_ssdt()` into following two
functions:
1. `wifi_ssdt_write_device()`: This function writes the device, its
address, _UID and _DDN.

2. `wifi_ssdt_write_properties()`: This function writes the properties
for WiFi device like _PRW, regulatory domain and SAR.

This split is done so that the device write can be skipped for
CNVi devices in follow-up CLs. It will allow the SoC controller
representation for CNVi PCI device to be consistent with other
internal PCI devices in the device tree i.e. not requiring a
chip driver for the PCI device.

Because of this change, _PRW and SAR will be seen in a separate
block in SSDT disassembly, but it does not result in any functional
change.

Observed difference:
Before:

Furquan Shaikh 507a98b689 drivers/wifi/generic: Move SMBIOS functions to a separate file
This change reorganizes the WiFi generic driver to move the SMBIOS
functions to a separate file. This change is done to reduce the noise
in generic.c file and improve readability of the file.

This change uses the helper function `acpigen_write_ADR_pci_device()`
to write _ADR object for the WiFi device.

Furquan Shaikh e31506cd51 drivers/wifi/generic: Do not generate SAR tables for non-Intel WiFi
CBFS SAR and SAR tables in ACPI are currently supported only by Intel
WiFi devices. This change adds a check in `emit_sar_acpi_structures()`
to ensure that the PCI vendor for the device is Intel before
generating the SAR tables.

Furquan Shaikh 44f14509ed drivers/wifi/generic: Limit scope of ACPI-related functions to generic.c
This change limits the scope of `wifi_generic_fill_ssdt()` and
`wifi_generic_acpi_name()` to generic.c since they are not used
outside of this file anymore. Also, since there is no need to split
SSDT generator into two separate functions,
`wifi_generic_fill_ssdt_generator()` is dropped and `.acpi_fill_ssdt`
directly points to `wifi_generic_fill_ssdt()`.

Furquan Shaikh 8262a2c718 drivers/{intel/wifi,wifi/generic}: Drop separate Intel WiFi driver
Currently, drivers/intel/wifi is a PCI driver (provides `struct
pci_driver`) as well as a chip driver (provides `struct
chip_operations`). However, there is no need for a separate chip
driver for the WiFi device since drivers/wifi/generic already provides
one.

Having two separate chip drivers makes it difficult to multi-source
WiFi devices and share the same firmware target without having to add
a probe property for each of these devices. This is unnecessary since
the WiFi driver in coreboot is primarily responsible for:
1. PCI resource allocation
2. ACPI SSDT node generation to expose wake property and SAR tables
3. SMBIOS table generation

For the most part, coreboot can perform the above operations without
really caring about the specifics of which WiFi device is being used
by the mainboard. Thus, this change drops the driver for intel/wifi
and moves the PCI driver support required for Intel WiFi chips into
drivers/wifi/generic. The PCI driver is retained for backward
compatibility with boards that never utilized the chip driver to
support Intel WiFi device. For these devices, the PCI driver helps
perform the same operations as above (except exposing the wake
property) by utilizing the same `wifi_generic_ops`.

This change also moves DRIVERS_INTEL_WIFI config to
wifi/generic/Kconfig.
