If we had an info device, it would fall into the same category as info 
cpu or info registers.  It duplicates the functionality of the gdbstub 
but it provides a convenience interface for those who don't have gdb 
connected.

Since there isn't really an obvious way to expose the device state via 
gdb without using Rcmd and a new monitor command, the whole debate seems 
academic :-)
