* This is the modern bootblock. It is used by platforms which select
|
|
* C_ENVIRONMENT_BOOTBLOCK, and it prepares the system for C environment runtime
|
|
* setup. The actual setup is done by hardware-specific code.
|
|
*
|
|
* It provides a bootflow similar to other architectures, and thus is considered
|
|
* to be the modern approach.
|
|
*
|
|
* This file is part of the coreboot project.
