From 47569cf3a9be5d42a75c932d4148fa20c2d8b475 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Thu, 12 Oct 2017 17:59:02 +0530 Subject: soc/intel/cannonlake: Use EBDA area to store cbmem_top address This patch uses BIOS EBDA area to store relevent details like cbmem top during romstage after MRC init is done. Also provide provision to use the same EBDA data across various stages without reexecuting memory map algorithm. BRANCH=none BUG=b:63974384 TEST=Ensures HW based memmap algorithm is executing once in romstage and store required data into EBDA for other stage to avoid redundant calculation and get cbmem_top start from EBDA area.
