	Cleanup to make the file follow the same convention after USE_MTCL was added and the depends structure was requested instead of the if guards.

2024-02-06	drivers/wifi: Add MTCL function to ACPI SSDT	David Ruth
	The MTCL function provides a country list to the Linux kernel via an ACPI function in SSDT for MediaTek WiFi chipsets that are capable of operating on the 6GHz band. The country list is used to selectively disable 6GHz and 5.9GHz operation based on the country the device is operating in. The function needs to read a binary file and send it as a package via the MTCL method in SSDT for PCIe WiFi with MediaTek chipsets. Change Summary: * Add src/drivers/wifi/generic/mtcl.c to abstract functionaltity related to MTCL * Add write_mtcl_aml function to convert the byte data into the format expected by the MTCL functionality in the Linux kernel. * Add validate_mtcl function to validate that the byte data read in from a file is in the expected format. * Add write_mtcl_function function to read a binary file called "wifi_mtcl".bin" from cbfs, then call validate_mtcl to verify that it is in an expected format, and if so write the aml via acpigen * Add config flag DRIVERS_MTK_WIFI to src/drivers/wifi/generic in order to include MediaTek WiFi specific functionality * Add config flag USE_MTCL which depends on DRIVERS_MTK_WIFI and enables including the specific ACPI function defined in SSDT * Add config flag CONFIG_MTCL_CBFS_FILEPATH which depends on DRIVERS_MTK_WIFI which enables configuring the file to add as "wifi_mtcl.bin" * Add a call to write_mtcl_function to src/drivers/wifi/generic/acpi.c to include the MTCL function in SSDT for MTK WiFi devices when USE_MTCL is enabled. * Add MediaTek VID to src/include/device/pci_ids.h.

2021-03-17	drivers/wifi, mb/google: Drop config `WIFI_SAR_CBFS`	Furquan Shaikh
	Now that SAR support in VPD is deprecated in coreboot, there is no need for a separate Kconfig `WIFI_SAR_CBFS` as the SAR table is only supported as a CBFS file. This change drops the config `WIFI_SAR_CBFS` from drivers/wifi/generic/Kconfig and its selection in mb/google/.../Kconfig. wifi_sar_defaults.hex is added to CBFS only if CONFIG_WIFI_SAR_CBFS_FILEPATH is not empty because current mainboards do not provide a default SAR file in coreboot. Thus, CONFIG_WIFI_SAR_CBFS_FILEPATH is updated to have a default value of "".

2020-10-13	drivers/{intel/wifi,wifi/generic}: Drop separate Intel WiFi driver	Furquan Shaikh
	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.

2020-10-13	drivers/{wifi/generic,intel/wifi}: Drop dependency on HAVE_ACPI_TABLES	Furquan Shaikh
	This change drops the dependency of DRIVERS_WIFI_GENERIC on HAVE_ACPI_TABLES as the driver provides operations other than the ACPI support for WiFi devices. Since the dependency is now dropped, ACPI operations in generic.c are guarded by CONFIG(HAVE_ACPI_TABLES).
