Let me name those two: - Colibri PXA270 Our customers already had to commit to a last-time-buy and we will phasing out shipments next year. I don't think anybody is doing any new designs with them since quite a while. - HP iPAQ Pocket PC h2200 A consumer device with PXA255 from back in 2002. There has not been any activity on h2200 from its maintainer Lukasz Dalek for almost 5 years now. Without anybody actually owning such hardware stepping up it will be quite impossible to maintain. > Do you want to take over > the MAINTAINER role from Marek for them? While I would love to do so I really don't think that makes too much sense at all. We probably should just drop PXA support entirely, move on and concentrate our resources on newer stuff like e.g. my patch sets for Apalis iMX8 and Colibri iMX8X which did not get any more attention since more resp. almost a month now.
