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