is there somewhere a list of embedded targets which are (well) supported by rust? i can't find one either on https://github.com/rust-embedded/awesome-embedded-rust or the rust book.

neither of these e.g. reference `cortex-m` / `cortex-m-rt` or `riscv` / `riscv-rt` & co.

just because [rustc has target support](https://doc.rust-lang.org/stable/rustc/platform-support.html) doesn't mean that there's already an RT for it (and HALs & co. at a higher level).

(i again just need something to reference)
