For example, the SRMMU present in v8 CPUs is 100% replaced with a totally different MMU (indeed, totally different instructions, access methods, etc) in v9. Accordingly there is very little code in common between the two ports, and most of that is in device handling; code that is in drivers/sbus and thus shared anyway. Something that made sense for sparc might not make sense for mips. -- Keith M Wesolowski <wesolows@foobazco.org> http://foobazco.org/~wesolows ------(( Project Foobazco Coordinator and Network Administrator ))------ "May Buddha bless all stubborn people!" -- Uliassutai Karakorum Blake
