|
| 42 | Routine Description:
|
| 43 | This service is called from Index == 0 until it returns EFI_UNSUPPORTED.
|
| 44 | It allows discontiguous memory regions to be supported by the emulator.
|
| 45 | It uses gSystemMemory[] and gSystemMemoryCount that were created by
|
| 46 | parsing the Windows environment variable EFI_MEMORY_SIZE.
|
| 47 | The size comes from the varaible and the address comes from the call to
|
| 48 | WinNtOpenFile.
|
| 49 |
|
| 50 | Arguments:
|
| 51 | Index - Which memory region to use
|
| 52 | MemoryBase - Return Base address of memory region
|
| 53 | MemorySize - Return size in bytes of the memory region
|
| 54 |
|
| 55 | Returns:
|
| 56 | EFI_SUCCESS - If memory region was mapped
|
| 57 | EFI_UNSUPPORTED - If Index is not supported
