- - Remote debugging interface for Am290*0 running MiniMON monitor, for GDB.
- This is like remote.c but expects MiniMON to be running on the Am29000
- target hardware.
- - Originally written by Daniel Mann at AMD for gdb 3.91.6.
- - David Wood (wood@lab.ultra.nyu.edu) at New York University adapted this
- file to gdb 3.95. I was unable to get this working on sun3os4
- with termio, only with sgtty. Because we are only attempting to
- use this module to debug our kernel, which is already loaded when
- gdb is started up, I did not code up the file downloading facilities.
- As a result this module has only the stubs to download files.
- You should get tagged at compile time if you need to make any
- changes/additions.
-*- Daniel Mann at AMD took the 3.95 adaptions above and replaced
- MiniMON interface with UDI-p interface.
