That is also what I am wondering about. Considering that previous BCM47xx platforms use a MIPS4k core and newer one use MIPS74k or later, you would not be able to build a single kernel for both which takes advantages of compile- time optimizations targetting MIPS74k. If this ist not a big concern, then let's target a single kernel. > Is there really a lot of shared code between SSB and HND/AI? > > It's true that there's currently a lot of device functionality built > into ssb.
