delete target dbug/picobug/dink32/m32r/mon2000 ?

[Pedro Alves]

All of these targets use gdb/monitor.c, which has bit rotted
years ago (I'd guess around ~6), and nobody seems to
have noticed.

I propose deleting them (along with monitor.c):

| target         | source               |
|----------------+----------------------|
| target dbug    | gdb/dbug-rom.c       |
| target picobug | gdb/microblaze-rom.c |
| target dink32  | gdb/dink32-rom.c     |
| target m32r    | gdb/m32r-rom.c       |
| target mon2000 | gdb/m32r-rom.c       |

Thanks,
Pedro Alves

I agree, that's an infrastructure whose time has come and gone.  (Not
much call for traditional ROM monitors when one can just as easily
boot to a real OS instead!) We would see references to people using
monitor backends from time to time, but I haven't seen any mentions
(with either new or old GDBs) in several years.

DINK32 was/is a free ROM monitor from Motorola
(now Freescale). I am not sure it is is available
or not. I haven't seen it in years personally.

I would expect microblaze-rom.c to be the newest user
of these.

I agree these are very likely dead.

Thanks.

Yeah, seems like it, added in 2009.

TBC, I'm not suggesting to remove any architecture support.
It should still be fine to debug microblaze, m68k/CF, etc.
with "target remote".

Although I added microblaze-rom.c in 2009, it was something
I received from Xilinx and I know nothing about it.  I don't
know if anyone has used it.  Offhand, it looks like cruft --
there are register names which don't exist on the MicroBlaze
processor.

Freescale still has it:

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=DINK32&nodeId=0152109D3F

But I didn't see anything newer than 2010.

(The real truth of the situation is that I added the dink32 support
somewhat hastily in 1997, we were demo'ing PPC hardware at ESC that
year...)
