Please note that as of today Marvell is also still producing them PXAs which are not to go end-of-life before later next year I believe. > IMHO it makes sense to drop only the XScale-specific tuning first and > to treat PXA (and similar CPUs) as a more generic armv5te. I wonder > what to do when GCC drops ARMv5 completely... I believe it was only an issue with early gcc 8 but does work just fine again with later 8.2 or 8.3 versions. However, what is more concerning to me is that in today's convoluted moloch known as U-Boot there may simply not be any space any more for something truly embedded but somewhat limited like PXA based hardware.
