39 | Creates and initializes the DebugImageInfo Table. Also creates the configuration\r |

48 | Notes:\r |
49 | This function allocates memory, frees it, and then allocates memory at an\r |
50 | address within the initial allocation. Since this function is called early\r |
51 | in DXE core initialization (before drivers are dispatched), this should not\r |
52 | be a problem.\r |

65 | Update the CRC32 in the Debug Table.\r |
