mb/google/sarien: Enable MAC address passthru support
Enable the support for providing a MAC address for a dock to use based on the VPD values set in the platform. BUG=b:123925776 TEST=tested on sarien by setting VPD values and observing the string returned by the AMAC() method: > vpd -i RO_VPD -s "ethernet_mac0"="AA:AA:AA:AA:AA:AA" > vpd -i RO_VPD -s "dock_mac"="BB:BB:BB:BB:BB:BB" 1) Test with no policy set, returns "dock_mac" ACPI Debug: "VPD region RW did not verify" ACPI Debug: "Found VPD KEY dock_mac = BB:BB:BB:BB:BB:BB" ACPI Debug: "MAC address returned from VPD: BB:BB:BB:BB:BB:BB" ACPI Debug: "AMAC = _AUXMAC_#BBBBBBBBBBBB#" 2) Test with policy set to "builtin", returns nothing > vpd -i RW_VPD -s "dock_passthru"="builtin" ACPI Debug: "Found VPD KEY dock_passthru = builtin" [AMAC returns Zero] 3) Test with policy set to "ethernet_mac0" > vpd -i RW_VPD -s "dock_passthru"="ethernet_mac0" ACPI Debug: "Found VPD KEY dock_passthru = ethernet_mac0" ACPI Debug: "Found VPD KEY ethernet_mac0 = AA:AA:AA:AA:AA:AA" ACPI Debug: "MAC address returned from VPD: AA:AA:AA:AA:AA:AA" ACPI Debug: "AMAC = _AUXMAC_#AAAAAAAAAAAA#" 4) Test with policy set to "dock_mac" > vpd -i RW_VPD -s "dock_passthru"="dock_mac" ACPI Debug: "Found VPD KEY dock_passthru = dock_mac" ACPI Debug: "Found VPD KEY dock_mac = BB:BB:BB:BB:BB:BB" ACPI Debug: "MAC address returned from VPD: BB:BB:BB:BB:BB:BB" ACPI Debug: "AMAC = _AUXMAC_#BBBBBBBBBBBB#" Change-Id: I90474e264cc433c0fd1a4b0dbaf98e5f74180d54 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/31670 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lijian Zhao <lijian.zhao@intel.com>
