Routine Description:

    This routine returns the initial platform memory map to the EFI core. The
    core maintains this memory map. The memory map returned does not need to
    take into account the firmware image itself or stack, the EFI core will
    reserve those regions automatically.

Arguments:

    Map - Supplies a pointer where the array of memory descriptors constituting
        the initial memory map is returned on success. The EFI core will make
        a copy of these descriptors, so they can be in read-only or
        temporary memory.

    MapSize - Supplies a pointer where the number of elements in the initial
        memory map will be returned on success.

Return Value:

    EFI status code.
