This is sort of a cross-posted issue from rust-embedded/cortex-m-quickstart#94

I'm getting started with a ATSAML10xxxx series project that uses Cortex M23 (ARM v8 baseline)

Since I'm new to Rust development (but already an experienced embedded developer), I've been following The Embedded Rust Book - Installing the tools. Specifically it suggests adding the following targets with rustup target add

• thumbv6m-none-eabi
• thumbv7m-none-eabi
• thumbv7em-none-eabi
• thumbv7em-none-eabihf

As for ARM v8 baseline, mainline and mainline with extension, the targets are respectively:

• thumbv8m.base-none-eabi (e.g. Cortex M23)
• thumbv8m.main-none-eabi (Not sure which arch uses this instruction set specifically 🤷‍♀️)
• thumbv8m.main-none-eabihf (e.g. Cortex M33, CortexM35P)

Could these be added to src/intro/install.md and also other places I've yet to come across?

Maybe a reference to the Cortex-M comparison table might help with picking out the right instruction set
