The patches are likely online somewhere, but I found the relevant ones that I have attached here. These are from the middle of my sun4m/sun4d removal patches, expect parts to be missed out and for sure they do not apply in your tree. I recall they were tested one-by-one via QEMU, but I did not test on real HW. Feel free to claim full authorship on patches where you do anything than trivial edits. I hope you will have fun working on this. Sam
