drivers/wifi: Support Wi-Fi 7 11be Enablement
Add 802.11be (aka. Wi-Fi 7) enable/disable support based on document 559910 Intel Connectivity Platforms BIOS_Guidelines revision 8.3. There are countries where Wi-Fi 7 should be disabled by default. This adds capability for OEM to enable or disable by updating the board specific Specific Absorption Rate (SAR) binary. BUG=b:348345300 BRANCH=firmware-rex-15709.B TEST=SSDT dump shows that the _DSM method returns the value supplied by the SAR binary for function 12 Change-Id: Ifa1482d7511f48f5138d4c68566f07ce79f37a7a Signed-off-by: Ravi Sarawadi <ravishankar.sarawadi@intel.com> Signed-off-by: Jeremy Compostella <jeremy.compostella@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/82207 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Subrata Banik <subratabanik@google.com> Reviewed-by: Eric Lai <ericllai@google.com> Reviewed-by: YH Lin <yueherngl@google.com>
