// Author(s):
// Contributors: gthomas, dmoseley
// Date: 1999-10-20
// Purpose:
// Description: It may be appropriate to relay directly into the stubs
// implementation of read memory, without board specific
// considerations such as checking the allowed ranges of
// addresses. Perhaps there needs to be some consideration
// of address spaces or, masking addresses.
//
// This file implements a default version of reading and writing
// memory when none of this is an issue
//
