Hi,
Here are two patches for remote debugging. The first one is pretty 
straightforward and just makes use of the last parameter to getpkt().
The second one changes banner printed after successful connection to 
gdbserver from "Remote debugging using :1234" to more informational
"Remote debugging from host whatever.name.com". When debugging via 
serial line, nothing changes.

Index: ChangeLog

	* remote.c: Added WAIT_FOREVER_FLAG and changed all
	calls to getpkt() to respect it.
	* gdbserver/remote-utils.c (remote_open): After successful
	connection the remote host name is printed instead of local
	port number.
