Remove support for "target m32rsdi" and "target mips/pmon/ddb/rockhopper/lsi"

Browse Source 
This removes support for:

 | target            | source                |
 |-------------------+-----------------------|
 | target m32rsdi    | gdb/remote-m32r-sdi.c |
 | target mips       | gdb/remote-mips.c     |
 | target pmon       | gdb/remote-mips.c     |
 | target ddb        | gdb/remote-mips.c     |
 | target rockhopper | gdb/remote-mips.c     |
 | target lsi        | gdb/remote-mips.c     |

That is:

 - Remote M32R debugging over SDI.

 - Debugging boards using the MIPS remote debugging protocol
   over a serial line, PMON, and a few variants.

These are the last non-"target remote" remote targets in the tree, if
you don't count "target sim".

@cindex @acronym{MIPS} boards
@value{GDBN} can use the @acronym{MIPS} remote debugging protocol to talk to a
@acronym{MIPS} board attached to a serial line. This is available when
you configure @value{GDBN} with @samp{--target=mips-elf}.
@need 1000
Use these @value{GDBN} commands to specify the connection to your target board:
@table @code
@item target mips @var{port}
@kindex target mips @var{port}
To run a program on the board, start up @code{@value{GDBP}} with the
name of your program as the argument. To connect to the board, use the
command @samp{target mips @var{port}}, where @var{port} is the name of
the serial port connected to the board. If the program has not already
been downloaded to the board, you may use the @code{load} command to
download it. You can then use all the usual @value{GDBN} commands.
For example, this sequence connects to the target board through a serial
port, and loads and runs a program called @var{prog} through the
debugger:
@smallexample
host$ @value{GDBP} @var{prog}
@value{GDBN} is free software and @dots{}
(@value{GDBP}) target mips /dev/ttyb
(@value{GDBP}) load @var{prog}
(@value{GDBP}) run
@end smallexample
@item target mips @var{hostname}:@var{portnumber}
On some @value{GDBN} host configurations, you can specify a TCP
connection (for instance, to a serial line managed by a terminal
concentrator) instead of a serial port, using the syntax
@samp{@var{hostname}:@var{portnumber}}.
@item target pmon @var{port}
@kindex target pmon @var{port}

You can control the timeout used while waiting for a packet, in the @acronym{MIPS}
remote protocol, with the @code{set timeout @var{seconds}} command. The
default is 5 seconds. Similarly, you can control the timeout used while
waiting for an acknowledgment of a packet with the @code{set
retransmit-timeout @var{seconds}} command. The default is 3 seconds.
You can inspect both values with @code{show timeout} and @code{show
retransmit-timeout}. (These commands are @emph{only} available when
@value{GDBN} is configured for @samp{--target=mips-elf}.)
The timeout set by @code{set timeout} does not apply when @value{GDBN}
is waiting for your program to stop. In that case, @value{GDBN} waits
forever because it has no way of knowing how long the program is going
to run before stopping.
@item set syn-garbage-limit @var{num}

Limit the maximum number of characters @value{GDBN} should ignore when
it tries to synchronize with the remote target. The default is 10
characters. Setting the limit to -1 means there's no limit.
@item show syn-garbage-limit

trying to synchronize with the remote system.

Show the current strings @value{GDBN} expects as the prompt from the
remote monitor.
@item set monitor-warnings
@kindex set monitor-warnings@r{, @acronym{MIPS} remote}
Enable or disable monitor warnings about hardware breakpoints. This
has effect only for the @code{lsi} target. When on, @value{GDBN} will
display warning messages whose codes are returned by the @code{lsi}
PMON monitor for breakpoint commands.
@item show monitor-warnings
@kindex show monitor-warnings@r{, @acronym{MIPS} remote}
Show the current setting of printing monitor warnings.
@item pmon @var{command}

This command allows sending an arbitrary @var{command} string to the
