From 2882253237f254d5f78b7531ef3cefb974cd4bbb Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Thu, 10 Oct 2019 15:50:04 +0200 Subject: nb/intel/nehalem: Move to C_ENVIRONMENT_BOOTBLOCK A few notable changes: - Microcode init is done in assembly during the CAR init. - The DCACHE_BSP_STACK_SIZE is set to 0x2000, which is the same size against which the romstage stack guards protected. - The romstage mainboard_lpc_init() hook is removed in favor of the existing bootblock_mainboard_early_init().
