From 1eaf64c723588d5fc9854d797d33ef0246b35b43 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Fri, 17 Jul 2020 14:35:26 -0700 Subject: soc/amd/picasso: Drop the inclusion of entry16.ld and reset16.ld This change drops the inclusion of entry16.ld and reset16.ld and instead adds the content of those files directly in memlayout_x86.ld in amd/picasso. This is done to allow the work for top-aligning bootblock to happen independent of Picasso layout. Once that is complete, Picasso layout can be re-evaluated to see if it can make use of the common bootblock linker file includes. TEST=Verified that coreboot.rom generated using --timeless is the same with and without this change for trembyle.
