/*
* This is the original bootblock used by coreboot on x86 systems. It contains
* a monolithic code flow, assembled from the following stages:
* - reset16.inc: the reset vector
* - entry16.inc: protected mode setup
* - entry32.inc: segment descriptor setup
* - CONFIG_CHIPSET_BOOTBLOCK_INCLUDE: chipset-specific initialization
* - generated/bootblock.inc: ROMCC part of the bootblock
*
* This is used on platforms which do not select C_ENVIRONMENT_BOOTBLOCK, and it
* tries to do the absolute minimum before walking CBFS and jumping to romstage.
*
* This file assembles the bootblock program by the order of the includes. Thus,
* it's extremely important that one pays very careful attention to the order
* of the includes.
