/* Use of the data cache is disabled because it loses for looking at
and changing hardware I/O ports and the like. Accepting `volatile'
would perhaps be one way to fix it, but a better way which would
win for more cases would be to use the executable file for the text
segment, like the `icache' code below but done cleanly (in some
target-independent place, perhaps in target_xfer_memory, perhaps
based on assigning each target a speed or perhaps by some simpler
mechanism). */
