  30 Routine Description:
  31
  32   Creates architecture-specific HOBs.
  33
  34   Note: New parameters should NOT be added for any HOBs that are added to this
  35         function.  BspStore is a special case because it is required for the
  36         call to SwitchStacks() in DxeLoad().
  37
  38 Arguments:
  39
  40   BspStore    - The address of the BSP Store for those architectures that need
  41                 it.  Otherwise 0.
  42
  43 Returns:
  44
  45   EFI_SUCCESS   - The HOBs were created successfully.
