@stephanosio Thanks for creating the issue. Will write the updates regarding the tooling for Tricore here.

Adding @go2sh here. IMO it makes sense to include openocd as well from https://github.com/tricore-oss/openocd

Yes. I have added OpenOCD to the list.

A plan would be to use a dedicate repo like for arc for the gcc and binutils similar arc. I doubt that tricore will be mainlined. qemu and openocd might be mainlined, but it will take some time. I'm preparing a recent version of the gcc and binutils toolchain based on our internal efforts.

Initial efforts for QEMU upstream is posted here: https://lore.kernel.org/qemu-devel/20260531-dev-ifx-tricore-upstream-rebase-minimal-v1-0-1c39053e5e95@linumiz.com/T/#u

Followup series will handle interrupt and TC18 handling.
