[PATCH 0/5] target/arm: Remove deprecated pxa CPUs and xscale/iwmmxt code

Posted by Peter Maydell 1 month ago

This patchset removes the pxa* CPU family, which we deprecated for
the 10.0 release and can now drop in 10.2.  The diffstat should
illustrate the motivation for the deprecation: it lets us delete
thousands of lines of xscale/iwmmxt specific emulation code which we
don't think anybody was using, which was unmaintained and which we
had no test coverage for.

thanks
