[RFC] New port: CR16 gdbserver

[Kaushik M Phatak <kphatak at gmail dot com>]

Hi,
Please find attached an updated patch for the gdbserver
port of the CR16 target.
This has been updated from my previous attempts of the same,
http://sourceware.org/ml/gdb-patches/2013-06/msg00490.html

I have tried to incorporate all feedback received from Pedro,
http://sourceware.org/ml/gdb-patches/2013-06/msg00734.html

>> isn't exposing r0_orig to gDB necessary for syscall restarting,
Added this register using separate target description feature.
This is part of the gdb patch posted earlier,
https://sourceware.org/ml/gdb-patches/2013-09/msg00140.html

The target description feature is added as features/cr16-linux.xml.
This will generate the cr16-linux.dat in gdb/regformats which will be
used by the gdbserver.

>> Add empty line between describing comment and function definition.
>> "... is the return ..."
Fixed these in linux-cr16-low.c.

An updated gdb port for the same is also posted for this.
