/**
* @file post_codes.h
*
* This aims to be a central point for POST codes used throughout coreboot.
* All POST codes should be declared here as macros, and post_code() should
* be used with the macros instead of hardcoded values. This allows us to
* quicly reference POST codes when nothing is working
*
* The format for a POST code macro is
* #define POST_WHAT_WE_COMMUNICATE_IS_HAPPENING_WHEN_THIS_CODE_IS_POSTED
* Lets's keep it at POST_* instead of POST_CODE_*
*
* This file is also included by early assembly files. Only use #define s;
* no function prototypes allowed here
*
* DOCUMENTATION:
* Please document any and all post codes using Doxygen style comments. We
* want to be able to generate a verbose enough documentation that is useful
* during debugging. Failure to do so will result in your patch being rejected
* without any explanation or effort on part of the maintainers.
*
