+CoreInitializeDebugImageInfoTable (

+/*++
+
+Routine Description:
+
+  Creates and initializes the DebugImageInfo Table.  Also creates the configuration
+  table and registers it into the system table.
+
+Arguments:
+  None
+
+Returns:
+  NA
+
+Notes:
+  This function allocates memory, frees it, and then allocates memory at an
+  address within the initial allocation. Since this function is called early
+  in DXE core initialization (before drivers are dispatched), this should not
+  be a problem.

+CoreUpdateDebugTableCrc32 (

+/*++
+
+Routine Description:
+
+  Update the CRC32 in the Debug Table.
+  Since the CRC32 service is made available by the Runtime driver, we have to
+  wait for the Runtime Driver to be installed before the CRC32 can be computed.
+  This function is called elsewhere by the core when the runtime architectural
+  protocol is produced.
+
+Arguments:
+  None
+
+Returns:
+  NA

+/*++
+
+Routine Description:
+
+  Adds a new DebugImageInfo structure to the DebugImageInfo Table.  Re-Allocates
+  the table if it's not large enough to accomidate another entry.
+
+Arguments:
+
+  ImageInfoType     - type of debug image information
+  LoadedImage       - pointer to the loaded image protocol for the image being loaded
+  ImageHandle       - image handle for the image being loaded
