| * 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. |
