2020-10-13drivers/wifi/generic: Do not generate SAR tables for non-Intel WiFiFurquan Shaikh
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.

2020-10-13drivers/wifi/generic: Limit scope of ACPI-related functions to generic.cFurquan Shaikh
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()`.

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).

2020-10-11drivers/wifi: Drop maxsleep parameter from chip configFurquan Shaikh
This change drops maxsleep parameter from chip config and instead hardcodes the deepest sleep state from which the WiFi device can wake the system up from to SLP_TYP_S3. This is similar to how other device drivers in coreboot report _PRW property in ACPI. It relieves the users from adding another register attribute to devicetree since all mainboards configure the same value. If this changes in the future, it should be easy to bring the maxsleep config parameter back.

2020-06-19Kconfig: Escape variable to accommodate new Kconfig versionsPatrick Georgi
Kconfig 4.17 started using the $(..) syntax for environment variable expansion while we want to keep expansion to the build system. Older Kconfig versions (like ours) simply drop the escapes, not changing the behavior. While we could let Kconfig expand some of the variables, that only splits the handling in two places, making debugging harder and potentially messing with reproducible builds (e.g. when paths end up in configs), so escape them all.
