[<sfo...@us...>]

Update of /cvsroot/xtensa/linux/arch/xtensa/mm
In directory usw-pr-cvs1:/tmp/cvs-serv975/arch/xtensa/mm

Modified Files:
	init.c 
Log Message:
First functional checkin of kgdb.  Reading AR registers does not work yet.  (Reading A registers works.)

Currently uses ttyS1 at 9600 8N1.  Serial port and baud rate to become paramterized.

To use, must have CONFIGURE_KGDB.  Must also pass the parameter "gdb" to the kernel to tell it to stop on boot and wait for a connection from gdb.
