Summary

After compiling a custom FIQ handler with the latest zynq-rs, master still run the "dummy fiq handler" instead of the custom one.
Also, if a custom FIQ handler is not provided at artiq-zynq, the compiler will complain about the missing FIQ function

However, satman will enter the custom FIQ handler no problem. And not tested on standalone.

Error log

I suspect Rust feature flags need to be passed across crate dependencies. Probably this is currently not done properly and you end up with several versions of zynq-rs (or its constituent crates) with different feature flags.
