This is what I was thinking. Its doable, right? since in ubinize we have all data required for constructing fastmap. From all your discussions with Artem I figure we can expect quite a few changes to the fastmap implementation. Is the layout also going to change? I remember you mentioning such idea in one of the emails. Thanks, Tanya Brokhman -- Qualcomm Israel, on behalf of Qualcomm Innovation Center, Inc.
