The PXA machines that we support in kernel and qemu are either industrial/embedded machines or upgraded versions of the SA1100 PDAs (sharpsl), not phones. OTOH, these chips came out between 2003 and 2007 so I can also see how people at the time had already moved away from using pure PDAs to Symbian or Blackberry phones, so there might just be fewer PDAs that got sold with PXA than with SA1100 before there were smartphones.
