Why do we need BATL_MEMCOHERENCE on 8641 but not on 8610?
dual core on 8641, single core on 8610.
The 8610 does lots of DMA for audio and video. Don't we need coherence for that? I read the e600 manual, but I couldn't glean whether we need the M bit set to make DMA work.
No, "M" in the core is only for other cores, has nothing to do w/DMAs.
