The pxa2xx CPUs are now only useful with user-mode emulation, because we dropped all the machine types that used them in 9.2. (Technically you could alse use "-cpu pxa270" with a board model like versatilepb which doesn't sanity-check the CPU type, but that has never been a supported config.) To use them (or iwMMXt emulation) with QEMU user-mode you would need to explicitly select them with the -cpu option or the QEMU_CPU environment variable. A google search finds no examples of anybody doing this in the last decade; I don't believe the GCC folks are using QEMU to test their iwMMXt codegen either. In fact, GCC is in the process of dropping support for iwMMXT entirely. The iwMMXt emulation is thousands of lines of code in QEMU, and is now the only bit of Arm insn decode which doesn't use decodetree. We have no way to test or validate changes to it. This code is just dead weight that is almost certainly not being used by anybody. Mark it as deprecated.
