The attach is the patch file for MIPS architecture to make the source codes in hal/mips/arch/ directory comply with MIPS I ISA. There are mainly two kinds of modification: 1. Add a delay slot after lw insn. 2. Change non-MIPS I insn. to equiv. MIPS I insn. I hope you in Cygnus could accept this patch. And, any further modification to the hal/mips/arch/ will not use instructions other than MIPS I.
