Thanks for the link! Added to our bullet point about the target spec
file in https://github.com/Rust-for-Linux/linux/issues/2.
Cheers,

They need to be in u

Hmm... So

Since we should try to go away from using `target.json`: what was not
possible to enable via e.g. `-Ctarget-feat
Enable rust for linux by implement generate_rust_target.rs
and select relevant Kconfig options.
We don't use builtin target as there is no sutiable baremetal
target for us that can cover all ISA variants supported by kernel.
