14   PeiDebug.h
15 
16 Abstract:
17 
18   PEI Debug macros. The work needs to be done in library. The Debug
19   macros them selves are standard for all files, including the core.
20 
21   There needs to be code linked in that produces the following macros:
22 
23   PeiDebugAssert(file, linenumber, assertion string) - worker function for
24       ASSERT. filename and line number of where this ASSERT() is located
25       is passed in along with the stringized version of the assertion.
26 
27   PeiDebugPrint - Worker function for debug print
28 
29   _DEBUG_SET_MEM(address, length, value) - Set memory at address to value
30     for legnth bytes. This macro is used to initialzed uninitialized memory
31     or memory that is free'ed, so it will not be used by mistake.
