From cf5af24a94b614bbc3f3fb531eb5cccf2d8e00c6 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Mon, 4 Nov 2019 21:24:28 +0100 Subject: soc/intel/common/sa: Remove EBDA dependency MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Saving cbmem_top across stages is not needed anymore so EBDA should not be used. The guard to cbmem_top_chipset implementation was inappropriate.
