Routine Description:
|
|
This service is called from Index == 0 until it returns EFI_UNSUPPORTED.
|
|
It allows discontiguous memory regions to be supported by the emulator.
|
|
It uses gSystemMemory[] and gSystemMemoryCount that were created by
|
|
parsing the host environment variable EFI_MEMORY_SIZE.
|
|
The size comes from the varaible and the address comes from the call to
|
|
WinNtOpenFile.
|
|
|
|
Arguments:
|
|
Index - Which memory region to use
|
|
MemoryBase - Return Base address of memory region
|
|
MemorySize - Return size in bytes of the memory region
|
|
|
|
Returns:
|
|
EFI_SUCCESS - If memory region was mapped
|
|
EFI_UNSUPPORTED - If Index is not supported
