Detailed Description

A TranslatingPortProxy in FS mode translates a virtual address to a physical address and then calls the read/write functions of the port.

If a thread context is provided the address can alway be translated, If not it can only be translated if it is a simple address masking operation (such as alpha super page accesses).
