From c19c704c02da663d1def525b07228a843b0962a0 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Mon, 30 Mar 2020 21:56:07 -0500 Subject: sb/intel/i82801ix: drop IGD-related NVS variables NDID/DID entries are no longer used by the GMA SSDT generator, so drop them. SSDT generation will be simplified in a subsequent commit. Remove direct setting of gnvs->ndid in qemu-q35 board since build will otherwise break.
