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.
|
|
|
|
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

Routine Description:

Return the FD Size and base address. Since the FD is loaded from a

Arguments:
|
|
Index - Which FD, starts at zero.
|
|
FdSize - Size of the FD in bytes
|
|
FdBase - Start address of the FD. Assume it points to an FV Header
|
|
FixUp - Difference between actual FD address and build address
|
|
|
|
Returns:
|
|
EFI_SUCCESS - Return the Base address and size of the FV
|
