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. BUG=chrome-os-partner:60821 TEST=Enable USE_SAR, boot reef to OS, create the VPD entry, reboot, check the SSDT dump and verify WRDS and EWRD structures.

Keep this enabled by default as most x86 platforms could have PCI-e slots equipped with one of these Intel WiFi adapters. The Kconfig entries under google boards had no function previously, the variable was never referenced.

2016-06-02drivers/intel/wifi: Add support for generating SSDT tableDuncan Laurie
Intel WiFi devices that support wake-on-wifi need to declare a Power Resource for this wake pin. Typically this has been done with a static declaration in the DSDT for each mainboard. By adding it to the existing intel/wifi driver it can be done based on a configuration register in the devicetree. Additionally the WiFi regulatory domain can be set in the SSDT directly instead of needing to use NVS to pass the value to the DSDT. Also add device IDs for Wilkins Peak 2 and Stone Peak 2 devices that are found on Chromebooks, and clean up a long line and some comment formatting. This was tested by booting on an HP Chromebook 13 device and comparing that the output in the SSDT matches what used to be in the DSDT. The WRDD value is read from VPD, if present, not from devicetree.cb. Additionally the case where CONFIG_DRIVERS_INTEL_WIFI is enabled but the wifi device is not described in devicetree.cb is tested to ensure it still generates the AML but does not include the _PRW wake pin. Example: devicetree.cb: device pci 1c.0 on chip drivers/intel/wifi register "wake" = "GPE0_DW0_16" device pci 00.0 on end end end VPD: "region"="us" SSDT.dsl: Scope (\_SB.PCI0.RP01) { Device (WIFI) { Name (_UID, Zero) Name (_DDN, "Intel WiFi") Name (_ADR, 0x00000000) Name (_PRW, Package () { 16, 3 }) Name (WRDD, Package () { Zero, Package () { 0x00000007, 0x00004150 } }) } } Change-Id: I8b5c916f1a04742507dc1ecc9a20c19d3822b18c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/15019 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2016-03-08intel/wifi: Add WRDD ACPI methodDuncan Laurie
Add an ACPI file containing a generic WRDD method that is used by Intel wireless kernel drivers to determine the country code to be used for regulatory domain configuration of the wireless radios. This requires an NVS variable called 'CID1' to provide an ISO-3166-2 alpha-2 country code or it will just return 0 instead. This is implemented as a bare method because this needs to be included directly into the wifi device that is defined by the mainboard as it may have board-specific settings like _PRW that need to be provided as well. BUG=chrome-os-partner:50516 BRANCH=glados TEST=boot on chell with 'region'='us' in VPD and see that it is properly read out by calling WRDD method on the WiFi device.

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
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.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
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. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
