From 8e646e74b3d5e1d4a5e8114f03046f3d7b6ad042 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Tue, 5 Jun 2018 11:19:22 +0200 Subject: cpu/intel/haswell: Use C_ENVIRONMENT_BOOTBLOCK This puts the cache-as-ram init in the bootblock. Before setting up cache as ram the microcode updates are applied. This removes the possibility for a normal/fallback setup although implementing this should be quite easy. Tested on Google peppy (Acer C720). Setting up LPC in the bootblock to output console on SuperIOs is not done in this patch, hence BOOTBLOCK_CONSOLE is not yet enabled by default.
