From 9fdd557f56064987a78abeefb7773136eb505461 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Fri, 6 May 2022 21:12:14 +0200 Subject: nb/intel/haswell: Introduce option to not use MRC.bin Introduce the `USE_NATIVE_RAMINIT` Kconfig option, which should allow booting coreboot on Haswell mainboards without the need of the closed source MRC.bin. For now, this option does not work at all; the needed magic will be implemented in subsequent commits. Add a config file to make sure the newly-introduced option gets build-tested.
