47 // Description: It may be appropriate to relay directly into the stubs
48 // implementation of read memory, without board specific
49 // considerations such as checking the allowed ranges of
50 // addresses. Perhaps there needs to be some consideration
51 // of address spaces or, masking addresses.
53 // This file implements a default version of reading and writing
54 // memory when none of this is an issue
