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

2020-10-13drivers/{wifi/generic,intel/wifi}: Drop dependency on HAVE_ACPI_TABLESFurquan 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).

2018-07-13intel/wifi: Add WGDS ACPI method for Geo Aware SARPratik Prajapati
To comply with all relevant bodies throughout the world, SAR settings take into account the lowest common denominator Tx power settings. This setup may lead to non-optimal performance when the user location is in a country that may allow higher power setting. The purpose of Wireless Geo Delta Settings (WGDS) is to provide offset settings for FCC, Europe, Japan and Rest of the world. These offsets would be added (by Intel wifi driver) to the base SAR Tx Power as defined in WRDS and EWRD BUG=b:65155728 BRANCH=none TEST=WGDS ACPI table gets created as expected.

2017-01-13intel/wifi: Create ACPI objects for wifi SAR configurationRobbie Zhang
To support intel wifi SAR configuration, it is required coreboot to publish two ACPI objects (WRDS and EWRD) to supply SAR limit data sets. VPD entry "wifi_sar" is required to supply the raw SAR limit data.
