Any volunteers? :) It requires huge amount of work,Well, it's actually quite straight forward. With the changes that got merged to 3.7, pxa3xx platforms boot, and I also ported some pxa specific peripheral drivers that should work for both 2xx and 3xx. Adding CPU support for 27x should also just be a matter of some extra lines. So I would clearly say you should give the DT approach a try first and see which bits are missing. And I would vote for not taking any new features for the legacy board support files but just bugfixes.Fair enough, I'll resend series without USB stuff (so it'll contain only bugfixes)
I rather wanted to encourage you to work on the PXA2xx DT stuff :) Please have a quick look at arch/arm/mach-pxa/pxa-dt.c - what it takes for basic 270 support is just copying the logic that is there already for the 3xx models. Some parts like the uart, host-mode usb, mmc, gpio-leds, gpio-keys, i2c etc are already finished and should work instantly. What's missing is the spi controller and the display, but maybe you can help getting these done? Thanks, Daniel
