/*++\r

Routine Description:\r
\r
  Creates and initializes the DebugImageInfo Table.  Also creates the configuration\r
  table and registers it into the system table.\r

Arguments:\r
  None\r
\r
Returns:\r
  NA\r
\r
Notes:\r
  This function allocates memory, frees it, and then allocates memory at an\r
  address within the initial allocation. Since this function is called early\r
  in DXE core initialization (before drivers are dispatched), this should not\r
  be a problem.\r

Routine Description:\r
\r
  Update the CRC32 in the Debug Table.\r
  Since the CRC32 service is made available by the Runtime driver, we have to\r
  wait for the Runtime Driver to be installed before the CRC32 can be computed.\r
  This function is called elsewhere by the core when the runtime architectural\r
  protocol is produced.\r

Routine Description:\r
