Here is one attached, the previously mentioned mioa701 board dts
file
I've been using for years (the date of the patch should be funny
enough). It was first submitted here :
https://lkml.org/lkml/2018/9/15/321
I'm not very sure pxa25x and pxa27x should survive though. Lately,
the
platform which I have left have 64MB of RAM, and cannot cope with
recent
binaries sizes. And to my best knowledge, pxa2xx architecture are
not
built anymore nor supported ...
The drivers might still be useful (the DMA, the SPI for intel CPU,
...).
Cheers.
