I have a functional CHERI-RISC-V RTEMS port already. Having a CHERI-AArch64 RTEMS port would be great, and it shouldn't be that much effort given that there's a CHERI-RISC-V port. Unfortunately, I can't work on that in the near future. That said, if anyone would be interested I'd be glad to help. There is also a new Slack channel [1] for anyone who's doing some CHERI work or just has questions. We can probably create a GSoC project idea for that as well.
