| Routine Description:

|   Creates and initializes the DebugImageInfo Table.  Also creates the configuration

| 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.

| 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
