Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Liblithium: A lightweight and portable cryptography library
I'm latching onto a non-main argument to be pedantic, but I'd like to mention that Rust is fine for _non-embedded_ kernel development too, in my experience.
As you're likely aware, Rust for embedded sucks when there's no HAL, but should be very pleasant otherwise. Have you looked into the cortex-a[1] crate?
Some unnecessary instructions could also be a part of an ongoing optimization effort[2][3].

Rust OS cortex a5
It looks like you can. I have no experience with this but you can also check out the rust channel of the embedded engineers discord for help if you hit a snag.

Use a custom linker script with lld
I advise you to look at how runtimes for embedded systems work (look at this on for example), as they also make heavy usage of linker scripts.
What are some alternatives?
cortex-m-quickstart - Template to develop bare metal applications for Cortex-M microcontrollers
scapegoat - Safe, fallible, embedded-friendly ordered set/map via a scapegoat tree. Validated against BTreeSet/BTreeMap.
cortex-m - Low level access to Cortex-M processors
actix-net - A collection of lower-level libraries for composable network services.
liblithium - A lightweight and portable cryptography library.
te - A parser, runtime and specification for the text expression language to make text processing human readable
syscall.rs - Raw system calls for Rust
bno055 - Device-agnostic Bosch Sensortec BNO055 9-axis Sensor Fusion IMU driver
rtic - Real-Time Interrupt-driven Concurrency (RTIC) framework for ARM Cortex-M microcontrollers
xargo - The sysroot manager that lets you build and customize `std`
