Deprecate our Unicore32 target support: * the Linux kernel dropped support for unicore32 in commit 05119217a9bd199c for its 5.9 release (with rationale in the cover letter: https://lkml.org/lkml/2020/8/3/232 ) * there is apparently no upstream toolchain that can create unicore32 binaries * the maintainer doesn't seem to have made any contributions to QEMU since the port first landed in 2012 * nobody else seems to have made changes to the unicore code except for generic cleanups either Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- We last considered this back in 2018, but in the end both QEMU and the kernel gave the port a stay of execution; the maintenance situation doesn't seem to have improved, and now the kernel has dropped support and especially given the lack of a toolchain I think it's time to start the deprecation process here. --- docs/system/deprecated.rst | 8 ++++++++ 1 file changed, 8 insertions(+)
