* Add an rp2040 specific #[entry] macro. This macro extends the one from cortex-m-rt by code to unlock all spinlocks on boot. * Idiomatic pointer arithmetic Apply suggestion by @9names, improving address calculations. (This doesn't change the generated code at opt levels 2 or "z".) Co-authored-by: 9names <60134748+9names@users.noreply.github.com>
