Update of /cvsroot/linux-mips/linux/arch/mips/ps2
In directory usw-pr-cvs1:/tmp/cvs-serv9789/arch/mips/ps2

Added Files:
	Makefile reset.c setup.c 
Log Message:
Started on R5900 integration.. as well as some basic PS2 code..



--- NEW FILE: Makefile ---
#
# Makefile for common code of Sony's PlayStation 2
#
# Note! Dependencies are done automagically by 'make dep', which also
# removes any old dependencies. DON'T put your own dependencies here
# unless it's something special (ie not a .c file).
