From 9065f4f8ed2facb60df3f4906b8e1e66e8958379 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Sat, 21 Nov 2020 02:12:54 +0100 Subject: soc/amd: move non-CAR linker scripts to common directory AMD family 17h and newer don't use cache as RAM, since the RAM is already initialized by the PSP when the x86 cores are released from reset. Therefore they use a different linker script as the rest of the x86 chips in coreboot do. Since there will be support for newer generations than Picasso will be added, move those linker scripts from soc/amd/picasso to soc/amd/common/block/cpu/noncar. TEST=Timeless build of amd/mandolin and amd/gardenia result in identical binaries.
