From 58ec51cc0aa3795d48b6d692a688017855d11baa Mon Sep 17 00:00:00 2001 From: Lean Sheng Tan Date: Wed, 9 Jun 2021 06:51:22 -0700 Subject: soc/intel/elkhartlake: Enable PCH GBE Enable PCH GBE with following changes: 1. Configure PCH GBE related FSP UPD flags 2. Use EHL own GBE ACPI instead of common code version due to different B:D.F from the usual GBE 3. Add kconfig PMC_EPOC to use the PMC XTAL read function Due to EHL GBE comes with time sensitive networking (TSN) capability integrated, EHL FSP is using 'PchTsn' instead of the usual 'PchLan' naming convention across the board.
