ok, we're out of time, so just to wrap up:

* there's the open raw_access PR swapping svd2rust to optionally use direct pointer access, but still using memory mapped structs; it removes volatile_cell but I'm not sure it solves the underlying issues? https://github.com/rust-embedded/svd2rust/pull/841
* there's an open risc-v PR https://github.com/rust-embedded/svd2rust/pull/856 that i've not had time to look at yet really
* if anyone's interested in helping maintain the stm32-rs PACs please let me know
