That is also what I am wondering about. Considering that previous BCM47= xx=20 platforms use a MIPS4k core and newer one use MIPS74k or later, you wou= ld not=20 be able to build a single kernel for both which takes advantages of com= pile- time optimizations targetting MIPS74k. If this ist not a big concern, t= hen=20 let's target a single kernel. > Is there really a lot of shared code between SSB and HND/AI? >=20 > It's true that there's currently a lot of device functionality built > into ssb.
